Today, I'll cover the announcements related to our IBM System Storage N series disk systems, which ties inwith Valentines Day theme nicely. The phrase we use for "unified storage" is that N series allows you to "share the closet, not necessarily the clothes". Couples recognize the value of a shared closet over having one closet for just the man's clothes, and a separate closet for just the woman's clothes. (For some couples, the man's closet would be terribly under utilized!). By analogy, the N series allows you to share one solution for LUNs that can be accessed via FCP or iSCSI protocols, and NAS file systems that can be accessed via NFS and CIFS protocols. In most data centers, Windows and UNIX applications are about as likely to share files as men and women are to wear each other's clothes, so the analogy is in tact.
Let's take a look at what got announced:
N7700 and N7900
There are actually [eight new high-end N series] models. the N7900 has 4 processors and 32GB of cache. The N7700 has 2 processors and 16GB cache. Each has two appliance models (A11 single node and A21 dual node) and two gateway models (G11 single node and G21 dual node).
The appliance models support both FC and SATA disk. The N7900 A models support a maximum of 1176 drives; the N7700 A models supports 840 drives. The gateway models provide FCP, iSCSI and NAS host access through external disk attachment. The N7900 gateway models support 1176 LUNs on external disk systems; the N7700 gateway models support 840 external LUNs.
N series now supports 1 TB SATA disk
The [EXN1000 expansion drawer] can now have up to fourteen 1TB SATA drives. This is in addition to previousannouncements supporting 500GB and 750GB drive capacities. These drawer support the entire N series line.
With 1 TB drives, the N7900 now supports up to 1176 TB of raw capacity, which is over 1PB of usabledata in 12+2P RAID-DP mode. This is greater than the internal disk capacity limits of current IBM DS8000, EMC DMX andHDS USP-V models.
At the low end, both the N3300 and N3600 now support 500GB, 750GB and 1TB SATA drives in addition to the SASdrives they supported.
SnapManager for Microsoft SharePoint
There is a new SnapManager in town. This one is for Microsoft SharePoint data. See the announcementfor the [N3300 and N3600] for details.
On Jan 24, IBM signed agreements with [Ingram Micro, Tech Data, and Synnex], to distribute the N Series products and work with IBM to recruit new solution providers to the line. These three are all well-respected world-class distribution providers, so weare glad to have increased our partnership with them on this.
Well, I'm back in Tucson, and thought I would close out my coverage of this year's Data Center Conference 2009 with some pictures. These first few are from the Solution Showcase.
There were four stations at the IBM booth. I had the "Information Infrastructure" station, you can see here I had my blook (blog-based book) on display "Inside System Storage: Volume I", a solid-state drive (in clear plexiglas to show all the chips inside), and the GUI panel for XIV.
What really stole the show was the IBM Portable Mobile Data Center (PMDC), which is a shipping crate with a fully running data center inside. In the one shown here, we had iDataPlex servers connected to an IBM XIV Storage System. Here is David Bricker striking a pose.
Inside, Monica Martinez shows off the iDataPlex servers. These are 1U servers that are only half as deep as regular servers, so you can pack 84 servers in the floorspace of 42 traditional 1U servers.
Two of these fit into a 2U chassis to share a common power supply and fan set. The trouble with traditional 1U servers is that fans do not have enough radius, so putting wider 2U fans for two servers gives you much better airflow.
Monica Martinez, Ruth Weinheimer, and Tamara Rice.
Mark your calendars! If you work in IT and have an interest in storage, then there are two upcoming conferences you might be interested in attending!
Join a network of your peers at
[IBM Pulse2012] who are fundamentally and cost-effectively changing the economics of IT and speeding the delivery of innovative products and services. With four days of top-notch education, Pulse 2012 will help you react with agility in changing competitive landscapes, reduce vulnerability throughout the service lifecycle, and continuously improve the business impact of the technology.
I presented at the very first IBM Pulse back in May 2008, which was a combination event to cover Tivoli Storage, Maximo and Netcool. For a bit of nostalgia, read my 2008 blog posts:
The IBM Pulse conference has certainly evolved over the past few years! The agenda is not yet finalized, so I don't know if I will be there again this year.
The second event has a new name. [IBM Edge2012] is the premier storage event that brings together innovative IBM technologies, world class training, leading industry experts, and compelling client success stories and best practices. Edge2012 is dedicated to helping you design, build and implement efficient storage infrastructure solutions.
We started doing these back in the mid-90s, entitled the "IBM Storage Symposium", then later the "IBM System Storage and Storage Networking Symposium". In 2007, I was there in Las Vegas presenting on a variety of topics. See my blog post [Storage Symposium 2007 recap].
In 2008, we had a version of the Storage Symposium down in Cuernavaca, Mexico. Not only did I present, but it was also a "book signing" event for my first book [Inside System Storage: Volume I]. Here were my blog posts: [Introduction], and [Conclusion]. We also had an event in the United States, as well as Montpelier, France, but since I already went to the one in Mexico, I let my colleagues go to these other ones instead.
In 2009, IBM experimented with combining two conferences under one roof in Chicago, IL. The IBM System Storage and Storage Networking Conference was combined with the IBM System x and BladeCenter Technical Conference. The idea was that server people would probably also be interested in storage, and storage admins might also be interested in x86-based servers. See my blog post
[Storage Symposium 2009 recap].
In 2010, System Storage and System x were once again combined, held in Washington DC, but the conferences were renamed to IBM System Storage Technical University and the IBM System x Technical University to give them a common look and feel. See my blog post [Storage University 2010 review].
In 2011, not satisfied that two data points was inconclusive, IBM continued the experiment, hosting both System Storage and System x conferences in Orlando, Florida. Here were my blog posts:
The results are now in. While I think it is admirable to run multiple conferences at the same time in the same place can help reduce costs and consolidate adminstration, it can have its drawbacks also. In the case of System Storage and System x, we learned a few things:
Having System x and Storage in the same conference gave the appearance that the conference was not focused on either. At smaller companies, there might be people who manage both x86 servers and storage, but at larger companies, servers and storage are managed by separate people, often in separate departments with different travel budgets.
Nearly all of IBM's storage attaches to IBM System x servers. However there are some clients that run AIX, IBM i or System z mainframes that might not have considered attending this conference, thinking that it was focused on storage for System x servers.
Both conferences were considered technical education, and might not have appealed to upper IT executives and directors as something to help make purchase decision from a business perspective, or to nework with peers of other decision makers.
The solution - IBM Edge. This conference is focused 100 percent on storage. There will be "Executive Edge" for decision makers to network with their peers, and "Technical Edge" for the storage admins to get the technical education they are looking for on IBM System Storage and Networking products and solutions. Please note that this conference was held in July or August in previous years, but will be held in June this year.
I am very excited about this new direction, and plan to be there in June 4-8 for this event!
Jamie Thomas, IBM General Manager of Storage and Software Defined Environments
Jamie announced [IBM Elastic Storage], a new offering that is available as a software defined storage solution, based on IBM's General Parallel File System (GPFS) technology already deployed at 45,000 installations.
IBM Elastic Storage provides a global name view across data center locations. It can manage up to a Yotabyte of information, combining Flash, disk and tape resources. It supports OpenStack interfaces, Hadoop and standard POSIX file system conventions.
IBM Elastic Storage provides automated tiering to move data from different storage media types. Infrequently accessed files can be migrated to tape and automatically recalled back to disk when required. Unlike traditional storage, it allows you to smoothly grow or shrink your storage infrastructure without application disruption or outages.
IBM Elastic Storage software can run on a cluster of x86 and/or POWER-based servers, and can be used with internal disk, commodity storage, or advanced storage systems from IBM or other vendors.
IBM partnered with various clients in different industries in a special beta program. Jamie led a client panel to discuss their experiences with IBM Elastic Storage:
Alan Malek, Director of IT, Cypress Semiconductor.
"Total cycle time is key". Over the past 31 years, they bought whatever file storage was available. Now, with IBM Elastic Storage, the performance was very consistent for their engineering workloads with full load balancing.
Russell Schneider, Principal Storage Consultant, Jeskell.
Russell's company works with a lot of federal agencies, "Big Data has become Bigger Data". For example, research on Global Warming and Climate Change requires a large amount of storage across agencies.
In another example, when the tsunami hit Japan a few years ago, an agency here in the USA realized they had 14PB of data stored as a single copy in a data center at sea level less than a mile from the coast. They realized they needed to have a secondary copy, and an option to cache to a third location depending on regional disasters.
Matthew Richards, Products, OwnCloud.
For those not familiar with OwnCloud, it provides a Dropbox-like file sharing service, but in the Enterprise, with on-premise storage. It has been fully tested and certified with IBM Elastic Storage to provide a secure file sharing platform.
With IBM Elastic Storage, they were able to scale linearly up to 20,000 users, and are now testing 100,000 users. The need to have intelligent access to files at scale is what Matthew likes about IBM Elastic Storage.
Dr. Michael Factor, IBM Distinguished Engineer at IBM Research
Michael started out explaining there are three areas for storage: block, file and object. The fastest growing type of data is unstructured fixed content with associated metadata. This is ideal for object storage. Michael has been working with OpenStack Swift, an open source interface defined for object storage. He defined "storlets" as follows:
Storlets extend an object store by moving computation to the data -- filtering, transforming, analyzing -- instead of bringing data to the computation.
Storlets have been deployed on a variety of European Union research projects. For example, in partnership with Phillips, a pathology storlet can count the number of cancer cells in an image. By bringing the computation to the data, it eliminates having to transfer large amounts of data over the network.
Storlets can run on-premise and on IBM's SoftLayer IaaS cloud offering.
Bruce Hillsberg, IBM Director of Storage Systems at IBM Research
Bruce led another panel discussion, this time of IBM storage experts:
Vincent Hsu, IBM Fellow and CTO of Storage.
The problem is the isolation of data into "storage silos". Isolation causes problems in managing large amounts of data at scale, and costs more as storage is not fully utilized. IBM Elastic Storage brings everything together, eliminating storage silos.
Michael explained how IBM works with clients all over the world to ensure that storage solutions meet client requirements. For example, storlets can be used to use rich metadata to manage photographs, and display them based on GPS satellite location, or other content that makes it easier to manage these images.
IBM Elastic Storage will support OpenStack Cinder and Swift interfaces. IBM is a platinum sponsor of OpenStack foundation, and is now its second most prolific contributor, with hundreds of full-time employees working on this.
Tom Clark, IBM Distinguished Engineer, Chief Architect, Storage Software, Cloud & Smarter Infrastructure.
Storage Management is a critical piece of Software Defined Storage. This is done in three ways:
The use of analytics to optimize the deployment of storage, based on workload requirements. Storage admins set policies, and then IBM Elastic Storage analytics gather metrics and then optimize data placement and movement based on these policies. IBM Elastic Storage has 70 percent lower TCO that competitive offerings.
The focus on backup services. Backups are not just for data protection, but rather can be used to duplicate or replicate data for testing, for training, and for other purposes. IBM Elastic Storage is fully supported by IBM Tivoli Storage Manager.
Being able to support Hybrid Cloud environments, where some data can be on-premise, and other data off-premise. Storage Management challenges will need to deal with this possibility. IBM Elastic Storage is well positioned for this.
Carl Kraenzel, IBM Distinguished Engineer, Director of Watson Cloud Technology and Support.
Watson is ground-breaking technology, and IBM Elastic Storage technology was at the heart of the Watson that was first introduced in 2011.
To consider IBM Elastic Storage based on lower-cost and higher-scalability is not the full picture. Rather, this is an important platform for Cognitive Computing, which we are just at the tip of the iceberg in exploring. IT systems need to be aware of the context of what we are doing.
While the Grand Challenge demonstration on Jeopardy! was exciting, it is time we stop playing games and apply IBM Elastic Storage to business, to help with health care and medical research, and other problems in society. IBM has already deployed this at Anderson Cancer Center and Memorial Sloan Kettering Cancer Center, for example.
Tom Rosamilia provided closing remarks. IBM Elastic Storage is not just for new workloads in Cloud, Analytics, Mobile and Social (CAMS) but also traditional workloads as well. IBM Elastic Storage provides "data democracy" and allows for "better rested storage administrators" that make fewer mistakes.
Tom opened the floor for questions from the audience:
Q1. Data integrity, not just security but also quality? IBM Elastic Storage has end-to-end data integrity checking built-in.
Q2. How does IT transition from full control to auto-pilot? IBM allows you to tap into existing storage. This is not rip-and-replace. With storage virtualization, IBM hides the complexity that normally requires full control over specific assets.
Q3. Storage admins would rather have a root canal without Novocaine than move their data. What is IBM doing to offer automation to help storage admins move to this new infrastructure? IBM storage virtualization breaks that hard link between applications and specific storage devices. IBM Elastic Storage eliminates application downtime previously associated with data movement.
Tom Rosamilia assured the audience that IBM is fully committed to its storage portfolio. IBM Elastic Storage is not just about the profoundness of what IBM announced today, but also where IBM is investing in the future of storage.
On Tuesday, I covered much of the Feb 26 announcements, but left the IBM System Storage DS8000 for today so that it can haveits own special focus.
Many of the enhancements relate to z/OS Global Mirror, which we formerly called eXtended Remote Copy or "XRC", not to be confused with our "regular" Global Mirror that applies to all data. For those not familiar with z/OS Global Mirror, here is how it works. The production mainframe writes updates to the DS8000, and the DS8000 keeps track of these in cache until a "reader" can pull them over to the secondary location.The "reader" is called System Data Mover (SDM) which runs in its own address space under z/OS operating system. Thanks to some work my team did several years ago, z/OS Global Mirror was able to extend beyond z/OS volumes and include Linux on System z data. Linux on System z can use a "Compatible Disk Layout" (CDL) format (now the default) that meetsall the requirements to be included in the copy session.
IBM has over 300 deployments of z/OS Global Mirror, mostly banks, brokerages and insurance companies. The feature can keep tens of thousands of volumes in one big "consistency group" and asynchronously mirror them to any distance on the planet, with the secondary copy recovery point objective (RPO) only a few seconds behind the primary.
Extended Distance FICON
Extended Distance FICON is an enhancement to the industry-standard FICON architecture (FC-SB-3) that can help avoid degradation of performance at extended distances by implementing a new protocol for "persistent" Information Unit (IU) pacing. This deals with the number of packets in flight between servers and storage separated by long distances, andcan keep a link fully utilized at 4Gpbs FICON up to 50 kilometers. This is particularly important for z/OS GlobalMirror "reader" System Data Mover (SDM). By having many "reads" in flight, this enhancementcan help reduce the need for spoofing or channel-extender equipment, or allow you to choose lower-costchannel extenders based on "frame-forwarding" technology. All of this helps reduce your total cost of ownership (TCO)for a complete end-to-end solution.
This feature will be available in March as a no-charge update to the DS8000 microcode.For more details, see the [IBM Press Release]
z/OS Global Mirror process offload to zIIP processors
To understand this one, you need to understand the different "specialty engines" available on the System z.
On distributed systems where you run a single application on a single piece of server hardware, you mightpay "per server", "per processor" or lately "per core" for dual-core and quad-core processors. Software vendors were looking for a way to charge smaller companies less, and larger companies more. However, you might end up paying the same whether you use 1GHz Intelor 4GHz Intel processor, even though the latter can do four times more work per unit time.
The mainframe has a few processors for hundreds or thousands of business applications.In the beginning, all engines on a mainframe were general-purpose "Central Processor" or CP engines. Based on theircycle rate, IBM was able to publish the number of Million Instructions per Second (MIPS) that a machine witha given number of CP engines can do. With the introduction of side co-processors, this was changed to "Millionsof Service Units" or MSU. Software licensing can charge per MSU, and this allows applications running in aslittle as one percent of a processor to get appropriately charged.
One of the first specialty engines was the IFL, the "Integrated Facility for Linux". This was a CP designatedto only run z/VM and Linux on the mainframe. You could "buy" an IFL on your mainframe much cheaper than a CP,and none of your z/OS application software would count it in the MSU calculations because z/OS can't run on theIFL. This made it very practical to run new Linux workloads.
In 2004, IBM introduced "z Application Assist Processor" (zAAP) engines to run Java, and in 2006, the "z Integrated Information Processor" (zIIP) engines to run database and background data movement activities.By not having these counted in the MSU number for business applications, it greatly reduced the cost for mainframe software.
Tuesday's announcement is that the SDM "reader" will now run in a zIIP engine, reducing the costs for applicationsthat run on that machine. Note that the CP, IFL, zAAP and zIIP engines are all identical cores. The z10 EC hasup to 64 of these (16 quad-core) and you can designate any core as any of these engine types.
Faster z/OS Global Mirror Incremental Resync
One way to set up a 3-site disaster recovery protection is to have your production synchronously mirrored to a second site nearby, and at the same time asynchronously mirrored to a remote location. On the System z,you can have site "A" using synchronous IBM System Storage Metro Mirror over to nearby site "B", and alsohave site "A" sending data over to size "C" using z/OS Global Mirror. This is called "Metro z/OS Global Mirror"or "MzGM" for short.
In the past, if the disk in site A failed, you would switch over to site B, and then send all the data all over again. This is because site B was not tracking what the SDM reader had or had not yet processed.With Tuesday's announcement, IBM has developed an "incremental resync" where site B figures out what theincremental delta is to connect to the z/OS Global Mirror at site "C", and this is 95% faster than sendingall the data over.
IBM Basic HyperSwap for z/OS
What if you are sending all of your data from one location to another, and one disk system fails? Do you declare a disaster and switch over entirely? With HyperSwap, you only switch over the disk systems, but leave therest of the servers alone. In the past, this involved hiring IBM Global Technology Services to implementa Geographically Dispersed Parallel Sysplex (GDPS) with software that monitors the situation and updates thez/OS operating system when a HyperSwap had occurred. All application I/O that were writing to the primary locationare automatically re-routed to the disks at the secondary location. HyperSwap can do this for all the disk systems involved,allowing applications at the primary location to continue running uninterrupted.
HyperSwap is a very popular feature, but not everyone has implemented the advanced GDPS capabilities.To address this, IBM now offers "Basic HyperSwap", which is actually going to be shipped as IBMTotalStorage Productivity Center for Replication Basic Edition for System z. This will run in a z/OSaddress space, and use either the DB2 RDBMS you already have, or provide you Apache Derby database for thosefew out there who don't have DB2 on their mainframe already.
Update: There has been some confusion on this last point, so let me explain the keydifferences between the different levels of service:
Basic HyperSwap: single-site high availability for the disk systems only
GDPS/PPRC HyperSwap Manager: single- or multi-site high availability for the disk systems, plus some entry-level disaster recovery capability
GDPS/PPRC: highly automated end-to-end disaster recovery solution for servers, storage and networks
I apologize to all my colleagues who thought I implied that Basic HyperSwap was a full replacement for the morefull-function GDPS service offerings.
Extended Address Volumes (EAV)
Up until now, the largest volume you could have was only 54 GB in size, and many customers still are using 3 GB and 9 GB volume sizes. Now, IBM will introduce 223 GB volumes. You can have any kind of data set on these volumes,but only VSAM data sets can reside on cylinders beyond the first 65,280. That is because many applications still thinkthat 65,280 is the largest cylinder number you can have.
This is important because a mainframe, or a set of mainframes clustered together, can only have about 60,000disk volumes total. The 60,000 is actually the Unit Control Block (UCB) limit, and besides disk volumes, youcan have "virtual" PAVs that serve as an alias to existing volumes to provide concurrent access.
Aside from the first item, the Extended Distance FICON, the other enhancements are "preview announcements" which means that IBM has not yet worked out the final details of price, packaging or delivery date. In many cases, the work is done, has been tested in our labs, or running beta in select client locations, but for completeness I am required to make the following disclaimer:
All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice. Availability, prices, ordering information, and terms and conditions will be provided when the product is announced for general availability.
Normally, IBM has its announcements on Tuesdays, but this week it was on Monday!
I am here in New York City, at the Kaufmann Theater of the American Museum of Natural History, for the
[IBM Storage Innovation Executive Summit]. We have about 250 clients here, as well as many bloggers and storage analysts.
My day started out being interviewed by Lynda from Stratecast, a division of [Frost & Sullivan]. This interview will be part of a video series that Stratecast is doing about the storage industry.
(About the venue: American Museum of Natural History was built in 1869. It was featured in the film "Night at the Museum". In keeping with IBM's focus on scalability and preservation, the museum here boasts skeletons of the largest dinosaurs. The five-story building takes up several city blocks, and the Kaufmann theater is buried deep in the bottom level, well shielded from cell phone or Wi-Fi signals allowing me to focus on taking notes the traditional way, with pen and paper.)
Deon Newman, IBM VP of Marketing for Northa America, was our Master of Ceremonies. Today would be filled with market insight, best practices, thought leadership, and testimonials of powerful results.
This is my first in a series of blog posts on this event.
Information Explosion on a Smarter Planet
Bridget van Kralingen, IBM General Manager for North America, indicated that storage is finally having its day in the sun, moving from the "back office" to the "front office". According to Google's Eric Schmidt, we now create, capture and replicate more date in two days than all of the information recorded from the dawn of time to the year 2003.
1928: IBM's innovative 80-column punch card stored nearly twice as much as its 50-column predecessor.
1947: Bing Crosby decided to do his radio show by recording it at his convenience on magnetic tape, rather than doing it live. This was the motivation for IBM researches to investigate tape media, delivering the first commercial tape drive in 1952. One tape reel could hold the equivalent of 30,000 punch cards.
1956: the IBM RAMAC mainframe was the first computer to access data randomly with an externally-attached disk system, the "350 Disk Unit", which stored 5 million 7-bit characters (about 5MB) and weighed over 500 pounds. Compare that today's cell phone that can store several GB of data in a handheld device.
1978: IBM invented Redundant Array of Independent Disks (RAID) through a collaboration with University of Berkeley.
1993: IBM introduces the [IBM 9337 Disk Storage Array], the first external disk storage system for distributed operating systems. This was based on the Serial Storage Architecture [SSA] protocol.
1995: IBM launches products that support Storage Area Networks (SAN), based on the Fibre Channel Protocol. IBM's internal codenames for disk products were all names of sharks, and so our internal mantra was that a healthy storage diet was comprised of "Plenty of Fish and Fibre".
2010: IBM ships Easy Tier, the world's easiest-to-use sub-LUN automated tiering capability, for the IBM System Storage DS8700 disk system.
Storage is growing (in capacity) at 40 percent per year, but IT budgets are only growing (in dollars) by a measly 1 to 5 percent. She cited the success at [Sprint], presented at the October 2010 launch. By combining IBM SAN Volume Controller with a three-tier storage architecture, Sprint lowered their raw capacity from 10PB to 8.4PB, increasing utilization from 35 to 78 percent. This involved shrinking from six storage vendors to three, and reducing total number of disk arrays from 166 down to 96. The resulting system has only 38 percent of their data on their most expensive Tier-1 storage, the rest is now living on less expensive Tier-2 and Tier-3 storage.
Companies are entering the era of Big Data with an insatiable appetite for collecting and analyzing data for marketplace insights. IBM [InfoSphere BigInsights], based on the Apache Hadoop, has helped customers make sense of it all. Innovative technology, expertise and marketplace insight will provide the competitive path forward in the coming decade.
Storage Challenges and Opportunities in 2011 and Beyond
I always enjoy hearing Stan Zaffos, Gartner Research VP, present at the annual [Data Center Conference] in Las Vegas every December. His analysis and research focuses on storage systems and emerging storage technologies.
Stan provided his perspective on the storage industry. He suggested a top-down approach, based on the market trends that Gartner is closely monitoring. He suggests focusing heavily on managing data growth, using SLAs to improve efficiency, and to follow Gartner's recommended actions. His statement, "If something is not sustainable, then it is unsustainable." resonated well with the audience. His key three points:
Design to meet but not exceed Service Level Agreements (SLAs)
Re-evaluate your ratio of SAN versus NAS based on growth of unstructured data content,
Explore the variety of Cloud options available.
Those of us who have been in this business a long time recognize that the problems haven't changed, just the dimensions. When in the past three decades were IT budgets generous and plentiful? When was there more than enough IT staff to handle all the requests in a timely manner? When hasn't there been a period of information growth? Gartner's analysis external control block (RAID protected disk systems) is growing revenue at 8.7 percent. Raw TBs of disk capacity is growing at 55 percent, and expected to be 100 Exabytes by 2015.
SAN has four times more revenue than NAS today, but NAS is growing faster. NAS was only 9 percent marketshare in 2010, but is projected to grow to 32 percent by 2015. SAN can offer higher price/performance for traditional OLTP and database workloads, but NAS is better suited for unstructured data, backups and archives, assisted by storage efficiency features like real-time compression and data deduplication. Which industries create the most unstructured data? The ones involved in filling out forms! This includes government, insurance agencies, manufacturing, mining and pharmaceuticals.
The phrase "good enough" should no longer be considered an insult. Too often IT departments design solutions that far exceed negotiated Service Level Agreements (SLAs), and they should instead focus on just meeting them instead. Modular storage systems are often sufficient for most workloads. Slower 7200RPM SATA disks can be one third the price of faster 15K RPM Fibre Channel drives, and often sufficient performance for the tasks required. Unified storage, such as IBM N series, can help simplify capacity planning, as storage can be re-purposed if different workloads grow at different rates. The key is to focus on meeting SLAs based on the price-vs-risk factor. Take a minimalist approach with fewer SLAs, fewer management classes, and fewer storage vendors.
Stan suggests a two-pronged approach: Capacity management through content analytics and classification, and Efficient Utilization through Thin Provisioning, storage virtualization, Quality of Service (QoS), compression and deduplication capabilities. This features will be ubiquitous by 2013. If you are worried that these technologies mean more information packed onto fewer devices, Stan's response was "If it's not there, it can't break." Storing data on fewer disks or tape cartridges means less chance something will fail.
Stan feels IT shops using Thin Provisioning should continue to charge their end-users on what they ask for (the full allocation request) rather than what the thin-provisioned amount actually is on the storage devices themselves. For example, if someone asks for 100GB LUN to be allocated to their system, but this only takes up 30GB of actual data space, chargeback the full 100GB!
It can take five years for new technology to get 50 percent adopted. The Romans took eight years to build the [Colosseum]. His research on "network convergence" found that 42 percent planned to use iSCSI, 32 percent Fibre Channel over Ethernet (FCoE) or other Top-of-Rack(TOR) converged switches, and 16 percent looking for full convergence of servers, switches and storage. Features like IBM Easy Tier automatic sub-LUN tiering were introduced later, and so have not been adopted as widely as other features like Thin Provisioning that have been around since the 1990's IBM RAMAC Virtual Array.
Stan felt that Public and Private clouds were two different approaches. Public clouds offer reservation-less provisioning. Private clouds offer improved agility, but can be more complex to set up, and has the risk of idle capacity similar to traditional IT datacenter deployments. Storage and File virtualization should be considered a pre-req for adopting Cloud technologies.
Storage IT teams need to adopt more than just technical skills. They need to learn about legal and government regulatory compliance issues, financial considerations, and would even benefit doing some "marketing". Why marketing? Because often IT departments need end-users to change their attitudes and behaviours, and this can be accomplished through internal marketing campaigns.
I've blogged about some of these videos already, but since there are probably a few out there buying the brand new Apple iPhone looking for YouTube videos to play on them, these links might provide some exampleentertainment on your new handheld device.
Next week has "Fourth of July" Independence Day holiday in the USA smack in the middle of the week, so I suspect the blogosphereto quiet down a bit. So whether you are working next week or not, in the USA or elsewhere, take some time to enjoy your friends and family.
Lakota Industries made news with the introduction of its [Sarah-Cuda Hunting Bow], named after moose-huntingU.S. Vice President nominee and Governor of Alaska [Sarah Palin]. This has all the same features as their other high-end hunting bows, but is lighter, smaller and available in Pink Camo. This "pink-it-and-shrink-it" move was designed to broaden the market share of hunting bows by reaching out to the needs of women hunters.
Not to be outdone, today, at the Storage Networking World Conference, IBM announced the new IBM System Storage SAN Volume Controller Entry Edition [SVC EE].
The new SVC Entry Edition, available in Flamingo Pink* or traditional Raven Black.
* RPQ required. Default color is Raven Black.
You might be thinking: "Wait! IBM SVC is already the leading storage virtualization product among SMB clients today,why introduce a less expensive model?" With the global economy in the tank, IBM thought it would be nice to help outour smaller SMB clients with this new option.
This new offering is actually a combination of new software (SVC 4.3.1) and new hardware (2145-8A4). Here are thekey differences:
by usable capacity managed, up to 8 PB
by number of disk drives, up to 60 drives
2145-4F2, 8F2, 8F4, 8G4, 8A4
1, 2, 3 or 4 node-pairs, depending on performance requirements
only one node-pair needed
FlashCopy, Metro Mirror and Global Mirror, licensed by subset of capacity used
FlashCopy, Metro Mirror and Global Mirror, but with simplified licensing
The SVC EE is not a "dumbed-down" version of the SVC Classic. It has all the features and functions of theSVC Classic, including thin provisioning with "Space-efficient volumes", Quality of Service (QoS) performance prioritization for more important applications, point-in-time FlashCopy, and both synchronous and asynchronous disk mirroring (Metro and Global Mirror).
While IBM has not yet have SPC-1 benchmarks published, IBM is positioning the SVC EE as roughly 60 percent of the performance, at 60 percent of the list price, compared to a comparable SVC Classic 2145-8G4 configuration. The SVC Classic is already one of the fastest disk systems in the industry. By comparison, the SVC EE is twice as fast as the original SVC 2145-4F2 introduced five years ago.If you outgrow the SVC EE, no problem! The 2145-8A4 can be used in traditional SVC Classic mode, and the SVC EE software can be converted into the SVC Classic software license for upgrade purposes, protecting your originalinvestment!
For those considering an HP EVA 4400 or EMC CX-4 disk system, you might want to look at combining an SVC EE with [IBM System Storage DS3400] disk. The combination offers more features and capabilities, and helps reduce your IT costs at the same time.
And if you are worried you can't afford it right now, IBM Global Financing is offering a ["Why Wait?" world-wide deferral of interest and payments] for 90 days, so you don't have to make your first payment until 2009, applicable to all IBM System Storage products, including the SVC EE, SVC Classic and DS3400 disk systems.
Continuing this week's theme of New Year's Resolutions for the data center, today we'll talk about one that many people make for their own personal lives: staying on a budget.
Often, when faced with a tightening budgets, we try to make more use of what we already have. Tell someone they are only using 10 percent of their brain, and they immediatelybelieve you; but tell them they are only using 30 percent of their storage, and they ask for a whitepaper,magazine article, or clarification on how that percentage is calculated. I actually visiteda customer that was only using6 percent of the storage attached to their Windows servers!
So, to help those of you making data center resolutions to stay on budget, the terms to remember are "Reduce", "Reuse" and "Recycle".
When people come to request storage, are they being reasonable about what they need today, or are they asking for what they might need over the next three years? They might need 50GB, but they ask for 100GB, in case they grow, and a year later, you find they have only 15GB of data on it. On the flipside, the person asks for what they need but some storage admins give out more, just so they don't have to be bothered so often when growth happens. Finally, I have seen this formalized into fixed size LUNs, all the disk is carved into big huge 100GB pieces, so if you need 20GB, here's one big enough with plenty of room to grow.
If you are going to keep on a budget, remember that storage today is 30% more expensive than storage next year. That is the average drop in both disk and tape on a dollar-per-MB basis. If there is any way to postpone giving out storage until it is actually needed, you can save a bundle of money. Timing is everything! In the event of a disaster, getting immediate replacement for disk can be very expensive, but if you can wait just two weeks, you can negotiate a better deal. I thought of this while going to the movie theatre yesterday. A "hot dog" and a bottle of water was $8.00, but if you are able to wait two hours and eat after the movie, you can get a much better meal for less.
A lot of companies buy new storage because their existing storage isn't fast enough, or doesn't have the latest copy services. This can easily be solved with an IBM SAN Volume Controller (SVC). The SVC can virtualize slower, functionless storage, and present to your application hosts virtual disks that are faster, and with all the latest disk-to-disk copy services like FlashCopy, Metro Mirror, and Global Mirror.
Chances are, you have unused disk capacity spread across all your storage today, but perhaps they are formatted into small LUNs. The SVC can combine the capacity, and let you carve up big LUNs at the sizes you need.This is like taking all those tiny pieces of soap in your shower and forming a new bar of soap, or taking all the crumbs at the bottom of your bread box, and making a new slice of bread. And, the virtual LUNs are dynamically expandable,so give out only the amount they need today, as it is simple to expand them to larger sizes later.
Of my 13 patents, the first will always be my favorite, on a function called "RECYCLE" for the Data Facility Storage Management Subsystem Hierarchical Storage Manager (DFSMShsm) product, which is now a component of the IBM z/OS operating system. Basically, tapes could contain hundreds or thousands of files, such as backup versions or archive copies, and these expired on different dates. As a result, a tape would be written100 percent full, and then over time, decrease in valid data to 80, 60, 40, 20 until it hit 0 percent. In some cases, a single filecould hold an entire tape hostage. RECYCLE was able to read the valid data off tapes that were perhaps less than 20 percent full, and consolidate them onto fewer tapes. As a result, a whole bunch of tapes could be returned to the scratch pool, and reused immediately for other workloads. This also helps in moving to newer, higher capacity cartridges, such as the new 700GB cartridge that IBM co-developed with FujiFilm.(This RECYCLE function exists in our IBM Tivoli Storage Manager software, as well as our Virtual Tape Server, but is called "reclamation" instead, to avoid confusion on searches.)
When evaluating your use of tape, determine if you are making best use of the tapes you have now, and perhaps a RECYCLE (or reclamation) scheme may be in order. Fewer tapes can save money in many ways, such as reduced storage costs, and reduced courier costs to send the tapes offsite. Tape media can still be 10-20 times less expensive than disk, based on full capacity.
Just in time for [Cyber Monday], Volume II of my "Inside System Storage" book series is now available. As I mentioned in my post on the [October 7th Launch announcement], I finally got past all the internal restrictions that prevented this volume from being published earlier.
My first book covered my initial 12 months of blogging experience, from September 2006 to August 2007. This book covers the history of my career transition from software engineer developer to marketing strategist.
My second book covers the next 8 months, from September 2007 to April 2008, spanning the acquisitions of XIV and Diligent companies that were part of an overall strategic re-alignment of storage within the broader "Systems and Technology Group" of IBM.
The books come in a variety of formats, including hardcover with dust jacket, paperback, and online eBook (PDF). My publisher, Lulu, now supports ePub format, so I am investigating the time and effort required to build this format from the source files.
Last week, a writer for a magazine contacted us at IBM to confirm a quote that writing a Terabyte (TB) on disk saves 50,000 trees. I explained that this was cited from UC Berkeley's famousHow Much Information? 2003 study.
To be fair, the USA Today article explains that AT&T also offers "summary billing" as well as "on-line billing", but apparently neither of these are the default choice. I can understand that phone companies send out bills on paper because not everyone who has a phone has internet access, but in the case of its iPhone customers, internet access is in the palm of your hands! Since all iPhone customers have internet access, and AT&T knows which customers are using an iPhone, it would make sense for either on-line billing or summary billing to be the default choice, and let only those that hate trees explicitly request the full billing option.
Sending a box of 300 pages of printed paper is expensive, both for the sender and the recipient. This informationcould have been shipped less expensively on computer media, a single floppy diskette or CDrom for example. Forthose who prefer getting this level of detail, a searchable digitized version might be more useful to the consumer.
Which brings me to the concept of Information Lifecycle Management (ILM). You can read my recent posts on ILM byclicking the Lifecycle tab on the right panel, or my now infamous post from last year about ILM for my iPod.
His recollection of the history and evolution of ILM fairly matches mine:
The phrase "Information Lifecycle Management" was originally coined by StorageTek in early 1990s as a way to sell its tape systems into mainframe environments. Automated tape libraries eliminated most if not all of the concerns that disk-only vendors tout as the problem with manual tape. I began my IBM career in a product now called DFSMShsm which specifically moved data from disk to tape when it no longer needed the service level of disk. IBM had been delivering ILM offerings since the 1970s, so while StorageTek can't claim inventing the concept, we give them credit for giving it a catchy phrase.
EMC then started using the phrase four years ago in its marketing to sell its disk systems, including slower less-expensive SATA disk. The ILM concept helped EMC provide context for the many acquisitions of smaller companies that filled gaps in the EMC portfolio. Question: Why did EMC acquire company X? Answer: To be more like IBM and broaden its ILM solution portfolio.
Information Lifecycle Management is comprised of the policies, processes,practices, and tools used to align the business value of information with the mostappropriate and cost effective IT infrastructure from the time information isconceived through its final disposition. Information is aligned with businessrequirements through management policies and service levels associated withapplications, metadata, and data.
Whitepapers and other materials you might read from IBM, EMC, Sun/StorageTek, HP and others will all pretty much tell you what ILM is, consistent with this SNIA definition, why it is good for most companies, and how it is not just about buying disk and tape hardware. Software, services, and some discipline are needed to complete the implementation.
While the SNIA definition provides a vendor-independent platform to start the conversation, it can be intimidatingto some, and is difficult to memorize word for word.When I am briefing clients, especially high-level executives, they often ask for ILM to be explained in simpler terms. My simplified version is:
Information starts its life captured or entered as an "asset" ...
This asset can sometimes provide competitive advantage, or is just something needed for daily operations. Digital assets vary in business value in much the same way that other physical assets for a company might. Some assets might be declared a "necessary evil" like laptops, but are tracked to the n'th degree to ensure they are not lost, stolen or taken out of the building. Other assetsare declared "strategically important" but are readily discarded, or at least allowed to walk out the door each evening.
... then transitions into becoming just an "expense" ...
After 30-60 days, many of the pieces of information are kept around for a variety of reasons. However, if it isn'tneeded for daily operations, you might save some money moving it to less expensive storage media, throughless expensive SAN or LAN network gear, via less expensive host application servers. If you don't need instantaccess, then perhaps the 30 seconds or so to fetch it from much-less-expensive tape in an automated tape librarycould be a reasonable business trade-off.
... and ends up as a "liability".
Keeping data around too long can be a problem. In some cases, incriminating, and in other cases, just having toomuch data clogs up your datacenter arteries. If not handled properly within privacy guidelines, data potentially exposes sensitive personal or financial information of your employees and clients. Most regulations require certain data to be kept, in a manner protected against unexpected loss, unethical tampering, and unauthorized access, for a specific amount of time, after which it can be destroyed, deleted or shredded.
So ILM is not just a good idea to save a company money, it can keep them out of the court room, as well as help save the environment and not kill so many trees. Now that 100 percent of iPhone customers have internet access, and a goodnumber of non-iPhone customers have internet access at home, work, school or public library, it makes sense for companies to ask people to "opt-in" to getting their statements on paper, rather than forcing them to "opt-out".
This week I am in beautiful Las Vegas for the Data Center 2010 Conference. While the conference officially starts Monday, I arrived on Sunday to help set up the IBM Booth (Booth "Z").
(Note: This is my third year attending this conference. IBM is a platinum sponsor for this event. The analyst company that runs this event has kindly asked me not to mention their name on this blog, display any of their logos, mention the names of any of their employees, include photos of any of their analysts, include slides from their presentations, or quote verbatim any of their speech at this conference. This is all done to protect and respect their intellectual property that their members pay for. This is all documented in a lengthy document in case I forget. So, if the picture of the conference backpack appears lopped off at the top, this was done intentionally to comply with their request. The list of sponsors at this event represents a "who's who" of the IT industry.)
The pre-conference orientation is for people who are first-timers, or for those who have not attended this conference in a while. The conference includes 7 keynote presentations and 68 sessions organized into seven "tracks" plus one "virtual track" which crosses the other seven:
Servers and Operating Systems
Cost Optimization "Virtual Track"
Each session is further classified as foundational versus advanced, business versus technical, and practical versus strategic.
The speaker also presented some unique methodologies that will be used this week, including "Magic Quadrant", "MarketScope", "Hype Cycle" and "IT Market Clock" which provide graphical representation to help attendees better understand the conference materials.
The Welcome Reception was sponsored by VCE, formerly known as Acadia, the coalition comprised of VMware, Intel, Cisco and EMC. I joked that this should be "VICE" so that Intel does not feel left out.
While we enjoyed drinks and snacks, we listened to live music from the all-violin band [Phat Strad].
The CEO of VCE, Michael Capellas, recognized me from across the room and came over to ask me how IBM was doing. We had a nice friendly chat about the IT industry and the economy.
IBM had some big announcements today. The theme for today's announcement was "Protected Information", as there are many reasons to protect your most strategic asset, your information. Let's do a quick run-down of a few of them.
IBM LTO generation 4
LTO 4 provides encryption at the drive level, and supports WORM cartridges similar to LTO 3. It continues the LTO consortium's strategy for higher capacity and faster performance. If you have LTO 1 or LTO 2, now is a good time to consider upgrading your tape technology. The combination of encryption and WORM protects your information against unauthorized access, and unethical tampering of the data. The support is from our largest automated tapelibrary (TS3500),to our smallest drives.
TS7520 Virtualization Engine
The TS7520replaces the TS7510, providing enhanced Virtual Tape Library (VTL) capability. When you hear "storage virtualization" you often think disk, but IBM invented "tape storage virtualization" and this product continues that leadership.
Support for Half-high LTO 3 drives
The TS3100 and TS3200 now support half-high LTO 3 drives, which means you can have twice the number of drives in each unit. LTO 4 drives can read and write to LTO 3 media, so this provides additional investment protection.
IBM System Storage DR550 File System Gateway
This new offering provides much-needed CIFS and NFS access to the DR550, the worlds most flexible compliance-and-retention storage available. Already there is a large body of ISVs that support the DR550 today, and with this new gateway, the list is even longer. The DR550 provides encryption for both disk and tape data, as well as policy-based non-erasable, non-rewriteable enforcement, designed for compliance with government regulations like Sarbanes-Oxley Act, HIPAA, and many others.
IBM System Storage SAN32B-3 switch
This is the first major deliverable from Brocade since their acquisition of McDATA. A powerful switch packs 4 Gbps support in a small 1U form factor. Start with 16 ports, then add in increments of 8 ports to a maximum of 32 ports.
I've provided all the links, so that you can delve deeply into all the data sheets.
I am just one of the speakers. We will have at each location the local IBM team and IBM clients giving testimonials. All the speakers will be available afterward for Q&A. It's shaping up to be an exciting series of events!
Continuing my week's theme on the XO laptop from the One Laptop Per Child [OLPC] foundation, I successfully managedto emulate my XO on another system.
Part of what is attractive of the XO laptop is the hardware, the high-resolution200dpi screen, the clever screen that rotates and folds flat into an eBook reader,and the water-tight, dust-proof keyboard. The other part is the software, howthey managed to pack an entire operating system, with useful applications, intoa 1GB NAND flash drive.
The drawback for developers like me is the risk of changing something that breaks the system. For example, my first attempt to create my own activityresulted in a blank space in my action bar, and my journal went into someinfinite loop, blinking as if it were still loading for minutes on end. I fixed it by deleting out the activity I created and rebooting.
To get around this, I successfully ran the disk-image under Linux's Virtual Machinesoftware called Qemu. This is an open source offering, with a proprietary add-onaccelerator called Kqemu. Here were the steps involved:
Base Operating System
Qemu is now available to run on Linux, Windows and OS X-Intel. I have an Ubuntu 7.04"Feisty Faun" version of Linux installed on my system from a project I did last year, so decided to use that.
Normally, "apt-get install qemu" would be enough, but I wanted to get the latest release, so I downloaded the [0.9.0 version]tarball of compiled binaries. Note that trying to compile Qemu from source requiresa downlevel gcc-3.x compiler, and my attempts to do this failed. The compiled binariesworked fine.
The Kqemu author hasn't packaged this for distribution, so I download the source code anddid my own compiles. You can do the "configure-make-install" using the regular gcc 4.1compiler and it went smoothly.
Getting Kqemu active was bit of a challenge. I had to make sense of Nando Florestan's[Installing Kqumu in Ubuntu] article,and the subsequent comments that followed.
There is a tiny [8MB Linux image]that should be used to verify the Kqemu is activated correctly.
The Disk Image
As with other development efforts, there are the older stable versions, and the bleedingedge development versions. I chose the 650 Build from the [Ship.2 stable versions], whichmatches the version on my XO laptop. The image comes as a *.bz2, which is a highly-compressedfile. Using "Bunzip2", the 221MB file expands to something like 932MB.
I renamed the resulting file to "build650.img"
Once I got all this done, I then made a simple script "launch" in my /home/tpearson/bin directory:
Then "launch build650.img" was all I needed to run the emulation. The full-screen mode helpsemulate the view on XO laptop. I was able to change the jabber server to "xochat.org" and see otherXO laptops online on my neighborhood view.
When running under Qemu, you can't just press Ctrl-Alt-something. For example, Ctrl-Alt-Erase onthe XO reboots the Sugar interface. However, do this on a Linux system, and it reboots your nativeX interface, blowing away everything.Instead, you press Ctrl-Alt-2 to get to the Qemu console, designated by (qemu) prompt,and then type:
Press "Ctrl-Alt-1" followed by "Ctrl-Alt" to get back to the emulated XO screen.
With this emulation, I am more likely to try new things, change files around, edit system files,and so on, without worrying about rendering my actual XO laptop unusable. Once debugged, I canthen work on moving them over to my XO, one at a time.
Well, it's Tuesday again, and you know what that means!
This Thursday is the Thanksgiving holiday here in the United States, so instead of announcing IBM products, I wanted to announce the general availability of my latest book, [Inside System Storage: Volume III].
This book includes blog posts from May 2008 to March 2009, along with the ever popular behind-the-scenes commentary on what was going on during IBM's launch of the Information Infrastructure initiative.
Do you know someone who celebrates Chanukah, Christmas, Kwanza, or the Winter Solstice, and have a hard time finding the right gift?
Do you know a client or IBM Business Partner that would appreciate a nominally-priced gift to thank them for their business?
Do you know someone newly hired into IBM or another IT company that could benefit from behind-the-scenes insight and commentary?
As with the other two volumes, Inside System Storage: Volume III is available in your choice of paperback, hardcover, and eBook (Adobe PDF) format.
In the spirit of Thanksgiving, I would like to thank my editor, Susan Pollard, who put in the extra effort, working evenings and weekends, to get this book done in time for the upcoming holiday season. For those outside the United States, there is an American tradition to shop in brick-and-mortar stores on Black Friday (the day after Thanksgiving) and to shop on-line for books like mine on Cyber Monday (the Monday after Thanksgiving).
I would also like to thank my publisher, Lulu.com, for upgrading me to "Spotlight" level, so now I have a spotlight page titled [Books Written by Tony Pearson], making it easy for you to order any of my books in various formats.
And last, but not least, I would like to thank all my friends and family that were supportive these past few difficult months while I was putting this book together.
Next month, I will be in Las Vegas, Dec 4-8, speaking at Gartner's [Data Center Conference]. If you order a book today, and bring it with you to the IBM booth at the Solution Expo, I can sign it for you!

In 2007, 51 percent of graduating college students could find jobs in their field, and this year it has dropped to only 20 percent. If you find yourself with some time on your hands, either recently graduated or recently unemployed, consider volunteerism.Last year, I chose to donate my time and money to an innovative project called "One Laptop per Child" [OLPC]. It was one of my [New Years Resolutions] for 2008. I was actually "recruited" by folks from the OLPC after they read my [series of blog posts] on things that can be done with their now famous green-and-white XO laptop.
The first half of the year, I spent helping "Open Learning Exchange Nepal" [OLE Nepal], a non-government organization (NGO) to help education in that country. XO laptops were provided to second and sixth graders at several schools, and my assignment was to help with the school "XS" server. This would be the server that all the laptops connect to. My blog posts on this included:
Rather than [Move to Nepal], I was able to help by building an identical XS server in Tucson, and provide support remotely. This included getting the "Mesh Antennas"to be properly recognized, having an internet filter using [DansGuardian] software, and working out backup procedures.
For the second half of the year, I was asked to mentor a college student inHyderabad, India as part of the ["Google Summer of Code"] to develop an[Educational Blogger System]on the XS server. We called it "EduBlog" and based it on the popular [Moodle] educational software platform.This was going to be tested with kids from Uruguay, but sending a serverdown to this country proved politically-challenging, so instead, I [builta server and shipped it] to a co-location facility in Pennsylvania that agreed to donate the cost and expenses needed to run the server there with full internet connection. I acted as "system admin" for the box, was able to connect remotely via SSH, while Tarun, the college student I was mentoring, developed the EduBlog software. Twice the system washacked, but I was able to restore the system remotely thanks to a multi-boot configuration that allowedme to reboot to a read-only operating system image and restore the operating system and data.
The students and teachers in Uruguay were helped locally by [Proyecto Ceibal]. We were able to translate the system into Spanish, and the project was a big success, enough to convince local government to provideXO laptops to their students to further the benefits.
The IBM Storage and Storage Networking Symposium in Las Vegas continues ...
N series and VMware
Jeff Barnett presented how VMware manages disk image files in its VMfs repository, and how N series offersa better alternative. Virtual machines can access N series volumes directly.
Business Continuity with System i
Allison Pate presented the various Business Continuity options for System i. Many customersuse internal storage for System i, but this then hampers Business Continuity efforts. Instead,you can have IBM System Storage DS8000 or DS6000 series disk systems provide disk mirroringbetween clustered systems.
There was a lot of interest in DR550, one of our many compliance storage solutions. Ron Henkhauspresented an overview of our DR550 and DR550 Express offerings. Unlike the competitive disk-onlysolutions, such as the EMC Centera, the DR550 allows you to attach an automated tape library, managing large amounts of fixed content data at a much lower cost point. It also has encryption, for both diskand tape data.
Open Systems Disk Management
Siebo Friesenborg presented the various steps needed to troubleshoot performance problemswith open systems, including the use of "iostat" on AIX systems as an example, and the stepsyou can take to make formal Service Level Agreements (SLA) between the IT department and thevarious lines of business.
IBM Encryption - TS1120 and LTO-4 encryption comparison
Tony Abete presented TS1120 and LTO-4 encryption techniques. Deploying encryption is more thanjust choosing a tape drive. There are a variety of factors involved, such as whether to managethe keys from the application, the operating system, or the library manager. You need policiesto decided when to encrypt tapes and when not to, generating your keys, storing them, and sharingthem with your business partners, suppliers and service providers with which you send tapes.
I can tell that many people are feeling like they are "drinking from a firehose".IBM's success in storage reaches out to so many different aspects of information management,a variety of industries, and disciplines as varied as regulatory compliance and medical imaging.
We are only days away from the big IBM Challenge of Watson computer against two human contestants on the show Jeopardy!
I watched two episodes of Jeopardy! on my Tivo, pausing it to follow the [homework assignment] I suggested in my last post. Here are my own results and observations.
Episode  involved a web programmer, a customer service representative, and a bank teller.
Of the first six categories in Round 1, I guessed four of the six themes for each category. For the category "Diamonds are Forever", I wrote down "All answers are some kind of gem or mineral", but the reality was that all the answers were some physical characteristic of diamonds specifically. For the category "...Fame is not", I wrote down "All answers are TV or Movie celebrities". I was close, but actually it was famous celebrities, rock bands and pop culture of the 1980s. (The movie "Fame" came out in 1980).
In the round, there were 27 of the 30 answers given before they ran out of time. Of these, I was able to get 24 of 27 correct by searching the Internet. That is 88 percent correct. Here were the ones that eluded me:
Answer related to a "multi-chambered mollusk". I could not find anything on the Internet definitively on this, so abstained from wager. The correct question was "What is Nautilus?".
Answer was the Irish variant of "Kathryne". I found Kathleen as a variant, but did not investigate if it had Irish origins. The correct question was "What is Caitlin?"
Answer was this Norse name for "ruler" whether you had red hair or not. I found "Roy" and "Rory" so guessed "What is Rory?" The correct question was "What is Eric?"
The second round, I guesed three of the six themese for the categories. For category "Musical Titles Letter Drop" I wrote down "All the answers are titles of musical songs" but it was actually "Musicals" as in the Broadway shows. For category "Place called Carson", I wrote down "All the answers are places" and was way off on that one, with answers that were people, places and names of corporations. And for "State University Alums", I wrote down "All the answers are college graduates", but instead they were all "State Universities" such as the University of Arizona.
In this second round, only 26 answers were posed. I got 80 percent correct with Internet searching. I missed three on the "Musical Titles", one in "Pope-pourri" and one State University (sorry SMU). The "Musical Titles Letter Drop category" was especially difficult, as for each title of a Musical, you had to remove a single letter out of it to form the correct response.
For the answer "Good luck when you ask the singers "What I Did For Love"; they never tell the truth", you would need to take "Chorus Line" the musical, where the song "What I did for Love" appears, and ask "What is Chorus Lie?" Note that "line" changed to "lie" and the letter "n" was dropped out.
For the answer "Embrace the atoms as Simba and company lose and gain electrons en masse in this production", you would need to recognize that Simba was the main character of "The Lion King" and change it to "What is The Ion King".
I think these play-on-words are the questions that would stump the IBM Watson computer.
In the final round, the category was "Ancient Quotes". I thought the answer would be a famous adage or quotation, but it was instead famous people who uttered those phrases. The answer was "He said, to leave this stream uncrossed will breed manifold distress for me; to cross it, for all mankind". I was able to determine the correct response readily from searching the Internet: The river was the Rubicon, the border of the Gaul region governed by an ambitious general. The correct response "Who was Julius Caesar?"
Total time for the entire exercise: 87 minutes.
The following night, episode  brought back Paul Wampler, the returning champion web programmer, against two new contestants: an actor, and high school principal.
Of the first six categories in Round 1, I guessed five of the six themes for each category. For the category "Nonce Words", I wrote all the answers would be nonsense words. I was close, the clues had words invented for a particular occasion, but the correct responses did not.
I was able to get 29 of 30 correct by searching the Internet. That is 96 percent correct. The one I missed was in the category "Nonce Words" and the answer was "In an arithmocracy, this portion of the population rules, not trigonometry teachers.." My response was "What is Math?" but the correct answer was "What are the majority?" It did not occur for me to even look up [Arithmocracy] as a legitimate word, but it is real.
The second round, I guesed five of the six themese for the categories. For category "Hawk" eyes, the "Hawk" was in quotation marks, so I wrote "All answers would start with the word Hawk or end with the word "eyes". I was close, the correct theme was that the word "hawk" would appear in the front, middle or end of the correct response.
In this second round, I got 28 of 30 correct. I got 93 percent correct with Internet searching. Ironically, it was the category "German Foods" that caught me off guard.
For, the answer was "Pichelsteiner Fleisch, a favorite of Otto von Bismarck, is this one-pot concoction, made with beef & pork". I know that "fleisch" is a German word for meat, so I guessed "What is sausage?" but the correct response was "What is stew?" I should have paid more attention to the "one-pot concoction" part of the answer.
For the answer was "Mimi Sheraton says German stuffed hard-boiled eggs are always made with a great deal of this creamy product". I didn't realize that "stuffed eggs" was German for "deviled eggs". Instead, I found Mimi Sheraton's "The German Cookbook" on Google Books, and jumped to the page for "Stuffed Eggs" The ingredients I read included whippedc cream, cognac, and worcestershire sauce. Taking the "creamiest" ingredient of these, I wrote down "What is whipped cream?" However, it turned out I was actually reading the ingredients for "Crabmeat Cocktail" that was coninuing from the previous page. I thought it was gross to put whipped cream with eggs, and should have known better. The correct response was "What is mayonnaise?"
In the final round, the category was "Political Parties". This could either be political organizations like Republicans and Democrats, or festivities like the Whitehouse Correspondents Dinner. The answer was "Only one U.S. president represented this party, and he said, I dread...a division of the republic into two great parties." So, we can figure out the answer refers to political organizations, but both Democrat and Republican are ruled out because each has had multiple presidents. So, looking at a [List of Political Parties of each US President], I found that there were four presidents in the Whig party, four in the Democrat-Republic party, but only one president in the Federalist party (John Adams), and one in the War Union party (Andrew Johnson). Looking at [famous quotes from John Adams] first, I found the quote, it matched, and so I wrote down "What is the Federalist party?". I got it right, as did two of the three contestants. Ironically, the one contestant who got it wrong, the returning champion web programmer, wagered a small amount, so he still had more money after the round and won the game overall.
Total time for the entire exercise: 75 minutes. I was able to do this faster as I skipped searching the internet for the responses I was confident on.

The BP oil spill in the Gulf of Mexico is a good reminder that all organizations should consider practice and execution of their contingency plans. In this most recent case, the [Deepwater Horizon] oil platform had an explosion on April 20, resulting in oil spewing out at an estimated 19,000 barrels per day. While some bloggers have argued that BP failed to plan, and therefore planned to fail, I found that hard to believe. How can a billion-dollar multinational company not have contingency plans?
The truth is, BP did have plans. Karen Dalton Beninato of New Orleans' City Voices discusses BP's Gulf of Mexico Regional Oil Spill Response Plan (OSRP) in her article [BP's Spill Plan: What they knew and when they knew it]. A
[redacted 90-page version of the OSRP] is available on their website.
The plan indicates that it may be 30 days from the time a deep offshore leak reaches the shoreline, giving OSRP participants plenty of time to take action.
(Having former politicians [blame environmentalists] for this crisis does not help much either. At least the deep shore rigs give you 30 days to react to a leak before the oil gets to the shoreline. Having oil rigs closer to shore will just shorten this time to react. Allowing onshore oil rigs does not mean oil companies would discontinue their deep offshore operations. There are thousands of oil rigs in the Gulf of Mexico. Extracting oil in the beautiful Alaska National Wildlife Reserve [ANWR] might be safer, it does not eliminate the threat entirely, and any leak there would be damaging to the local plant and animals in the same manner.)
So perhaps the current crisis was not the result of a lack of planning, but inadequate practice and execution. The same is true for IT Business Continuity / Disaster Recovery (BC/DR) plans. In all cases, there are four critical parts:
The planning team needs to anticipate every possible incident, determine the risks involved and the likelihood of impact, and either accept them, or decide to mitigate them. This can include natural disasters (hurricanes, fires, floods) and technical issues (computer viruses, power outages, network disruption).
Mitigation can involve taking backups, having replicated copies at a remote location, creating bootable media, training all of the appropriate employees, and having written documented procedures. IBM's Unified Recovery Management approach can protect your entire IT operations, from laptops of mobile employees, to remote office/branch office (ROBO) locations, to regional and central data centers.
When was the last time you practiced your Business Continuity / Disaster Recovery plan? I have seen this done at a variety of levels. At the lowest level, it is all done on paper, in a conference room, with all participants talking through their respective actions. These are often called "walk-throughs". At the highest level, you turn off power to your data center --on a holiday weekend to minimize impact to operating revenues-- and have the team bring up applications at the alternate site.
As many as 80 percent of these BC/DR exercises are considered failures, in that if a real disaster would have occurred, the participants are convinced they would not have achieved their target goals of Recovery Time Objective (RTO). However, they are not complete failures if they can help improve the plans, help identify new incidents that were not previously considered, and help train the participants in recovery procedures.
The last part is execution. In my career, I have been onsite for many Disaster Recovery exercises as well as after real disasters have occured. I am not surprised how many people assume that if they have plans in place, have made preparations, and have one to three practice drills per year, that the actual "execution" would directly follow. While the book [Execution] by Bossidy and Charan is not focused on IT BC/DR plans per se, it is a great read on how to manage the actual execution of any kind of business plan. I have read this book and recommend it.
If you have not tested out your IT department's BC/DR plans. Perhaps its time to dust off your copy, review it, and schedule some time for practice.
The Metro Atlanta Chamber (MAC) is focused on bringing businesses and jobs into the Metro Atalanta area, and to help its members connect with other companies that can help them thrive. The MAC cover the Metropolitan region of Atlanta (5.8 million people) and 28 counties in Georgia.
The event was called "Technology Thursday", where the MAC holds a meeting on the third Thursday of every month, to discuss technology issues. The audience was a mix of business owners, sales executives, and managers. The event allowed for people to network with each other, as well as learn something new from a subject matter expert. This was the last one for 2011, to avoid conflicts with upcoming holidays in November and December.
Many thanks to the 186 people who registered for yesterday's webcast "Solving the Storage Capacity Crisis -- Tools and Practices for Effective Management!" We had some excellent questions posed during the live Q&A:
Do you recommend moving to a SAN before implementing the management techniques you described, or will these tactics work just as well on direct-attached storage?
How does data center tiering differ from hierarchical storage management?
How do you recommend decisions about data priority be made when there are multiple stakeholders competing for attention?
You didn't mention deduplication. Does that have much impact on capacity management?
When outsourcing to a storage service provider, do you have any recommendations of the merits of wholesale outsourcing vs. partial outsourcing?
What are the dangers of giving end-users the ability to manage their own storage? What kind of education should be put in place?
The webcast was recorded, so in case you missed it, or just want to hear it again, the recording is now available in the [On24 archives].
Next week, once again, I will be blogging from beautiful Caesars Palace hotel in Las Vegas, Nevada to report on what I see and hear at the 29th annual Data Center Conference. Here are my posts from 12 months ago when I attended this conference in 2009:
Again we will have a Solutions Showcase with a Portable Modular Data Center (PMDC) and various exhibits. I will be manning the booths, stop on by. Plus, on Tuesday, I will be be speaking! My topic will be "Choosing the right storage for your server virtualization environment."
Those of you on twitter can follow me at [@az990tony] and hash tag #LSC29. I will be available for one-on-one consultations sessions. I am arriving Sunday morning, Dec. 5, and staying through Thursday afternoon, December 9.
Mark your calendars! Next month, IBM's Midsize Insider is hosting me as a speaker for a Webcast: [Storage Management with IBM], on August 7th, 12pm EDT. Midsize Insider is a valuable repository of expert content tailored for small-to-midsized business owners and IT decision makers.
The problems that used to keep storage managers awake at night -- power, cooling and physical footprint -- are being successfully addressed by technology, but a more vexing issue still remains: How to get more out of the limited supply of skilled storage management professionals.
Demand for storage capacity continues to grow far faster than the pool of people to manage it. With no end in sight to data growth, businesses need to apply technology and practices that distribute management responsibility to the people who need storage, and multiply the volumes of storage that skilled professionals can handle.
In this presentation, in this session, I will cover best practices and new tools that are enabling leaps in productivity, in three main areas:
Abandon the Craftsman Approach. Storage administrators need to discard some long-help myths about storage management and adopt new ways of thinking that enable them to handle significantly greater capacity.
Adopt software tools. Computers can now provide unprecedented guidance on storage optimization so that people don’t have to. Policy-based management, smart provisioning and automated tiering are among the innovations that are powering leaps in productivity.
Consider self-service portals. Companies are now exploring the self-service capabilities of private and public clouds. However, organizations need to adopt policies and limits in place to create an atmosphere of trust that enables efficient self-provisioning for storage.
A lot of people ask me about IBM branding, as we have recently changed brands. In the past we had two separate brands, one for servers (eServer) and one for storage (TotalStorage). These would be fine if we wanted to promote their independence, but customers today want synergy between servers and storage, they want systems that work well together.
Last year, in response to market feedback, we crated a new brand, "IBM Systems" and put all the server and storage product lines under one roof. Over time, we will transition from TotalStorage to System Storage naming. This will occur with new products, and major versions of existing products.
Two other phrases you will hear in the names of our offerings are "Virtualization Engine" and "Express". These are portfolio identifiers. The Virtualization Engine identifier was created to emphasize our leadership in system virtualization, and we have products that span product lines with this identifier.
The Express identifier was created to emphasize our focus on Small and Medium sized business (SMB). It spans not just servers and storage, but across other offerings from other IBM divisions.
Of course, just renaming products and services isn't enough. Systems don't work together just because they have similar names, are covered in similar "Apple white" plastic, or have similar black bezels. Obviously, thoughtful and collaborative design are needed, with the appropriate amounts of engineering and testing. IBM is aligning its server and storage development so that the IBM Systems brand keeps its promise.
Perhaps the recent financial meltdown is making storage vendors nervous.Both IBM and EMC gained market share in 3Q08, but EMC is acting strangelyat IBM's latest series of plays and announcements. Almost contradictory!
Benchmarks bad, rely on your own in-house evaluations instead
Let's start with fellow blogger Barry Burke from EMC, who offers his latest post[Benchmarketing Badly] with commentaryabout Enterprise Strategy Group's [DS5300 Lab Validation Report]. The IBM System Storage DS5300 is one of IBM's latest midrange disk systems recently announced. Take for example this excerpt from BarryB's blog post:
"I was pleasantly surprised to learn that both IBM and ESG agree with me about the relevance and importance of the Storage Performance Council benchmarks.
That is, SPC's are a meaningless tool by which to measure or compare enterprise storage arrays."
Nowhere in the ESG report says this, nor have I found any public statements from either IBM nor ESG that makes this claim. Instead, the ESG report explains that traditional benchmarks from the Storage Performance Council [SPC] focus on a single, specific workload, and ESG has chosen to complement this with a variety of other benchmarks to perform their product validation, including VMware's "VMmark", Oracle's Orion Utility, and Microsoft's JetStress.
Benchmarks provide prospective clients additional information to make purchasedecisions. IBM understands this, ESG understands this, and other well-respected companies like VMware, Oracle and Microsoft understand this. EMC is afraid that benchmarks mightencourage a client to "mistakenly" purchase a faster IBM product than a slower EMC product. Sunshine makes a great disinfectant, but EMC (and vampires) prefer their respective "prospects" remain in the dark.
Perhaps stranger still is BarryB's postscript. Here's an excerpt:
"... a customer here asked me if EMC would be willing to participate in an initiative to get multiple storage vendors to collaborate on truly representative real-world "enterprise-class" benchmarks, and I reassured him that I would personally sponsor active and objective participation in such an effort - IF he could get the others to join in with similar intent."
As I understand it, EMC was once part of the Storage Performance Council a long time ago, then chose to drop out of it. Why re-invent the wheel by creating yet another storage industry benchmark group? EMC is welcome to come back to SPC anytime! In addition to the SCP-1 and SPC-2 workloads, there is work underway for an SPC-3 benchmark. Each SPC workload provides additional insight for product comparisons to help with purchase decisions. If EMC can suggest an SPC-4 benchmark that it feels is more representative of real-world conditions, they are welcome to join the SPC party and make that a reality.
The old adage applies: ["It's better to light a candle than curse the darkness"]. EMC has been cursing the lack of what it considers to be acceptable benchmarks but has yet to offer anything more realistic or representative than SPC.What does EMC suggest you do instead? Get an evaluation box and run your own workloads and see for yourself! EMC has in the past offered evaluation units specifically for this purpose.
In-house evaluations bad, it's a trap!
Certainly, if you have the time and staff to run your own evaluation, with your own applications in your own environment, then I agree with EMC that this can provide better insight for your particular situation than standardized benchmarks.
In fact, that is exactly what IBM is doing for IBM XIV storage units, which are designed for Web 2.0 and Digital Archive workloads that current SPC benchmarks don't focus on. Fellow blogger Chuck Hollis from EMC opines in his post[Get yer free XIV!]. Here's an excerpt:
"Now that I think about it, this could get ugly. Imagine a customer who puts one on the floor to evaluate it, and -- in a moment of desperation or inattention -- puts production data on the device.
Nobody was paying attention, and there you are. Now IBM comes calling for their box back, and you've got a choice as to whether to go ahead and sign the P.O., or migrate all your data off the thing. Maybe they'll sell you an SVC to do this?
Yuck. I bet that happens more than once. And I can't believe that IBM (or the folks at XIV) aren't aware of this potentially happening."
Perhaps Chuck is speaking from experience here, as this may have happened with customers with EMC evaluation boxes, and is afraid this could happen with IBM XIV. I don't see anything unique about IBM XIV in the above concern. Typical evaluations involve copying test data onto the box, test it out with some particular application or workload, and then delete the data no longer required. Repeat as needed. Moving data off an IBM XIV is aseasy as moving data off an EMC DMX, EMC CLARiiON or EMC Celerra, and I am sure IBM wouldgladly demonstrate this on any EMC gear you now have.
Thanks to its clever RAID-X implementation, losing data on an IBM XIV is less likely thanlosing data on any RAID-5 based disk array from any storage vendor. Of course, there will always be skeptics about new technology that will want to try the box out for themselves.
If EMC thought the IBM XIV had nothing unique to offer, that its performance was just "OK",and is not as easy to manage as IBM says it is, then you would think EMC would gladly encourage such evaluations and comparisons, right?
No, I think EMC is afraid that companies will discover what they already know, that IBM has quality products that would stand a fair chance of side-by-side comparisons with their own offerings.We have enough fear, uncertainty and doubt from our current meltdown of the global financial markets, don't let EMC add any more.
Have a safe and fun Halloween! If you need to add some light to your otherwise dark surroundings, consider some of these ideas for [Jack-O-Lanterns]!
Well, it was Tuesday again, and we had quite a lot of announcements here at IBM this week!
Over 1,800 clients attended the [Live February 5 webcast]! The announcements were all part of IBM's SmartCloud Storage portfolio. Here are the highlights:
STN7800 Real-time Compression Appliance
Back in October 2010, IBM announced the acquisition of Storwize, Inc., renaming its NAS-compression units to the IBM Real-time Compression appliances. Some folks were confused, so I had a blog post [IBM Storwize Product Name Decoder Ring].
IBM initially offered two models:
The [STN6500 model] had 16 Ethernet ports 1GbE (16x1GbE) and a pair of four-core processors.
The [STN6800 model] had either eight 10GbE ports (8x10GbE), or four 10GbE plus eight 1GbE ports (4x10GbE+8x1GbE). It has a pair of six-core processors.
Now, IBM offers the [STN7800 model], which can replace either of the ones above, offering 16x1GbE, 8x10GbE, and 4x10GbE+8x1GBE port configurations. It has a pair of eight-core processors to handle more robust Cloud Storage environments. See [Announcement Letter 113-012] for more details.
New XIV Gen3 model 214
With its awesome support for VMware, the XIV is often chosen for Cloud storage. The new XIV model 214 now offers up to a dozen 10GbE ports, or you can stay with the 22 1GbE ports available on previous models. These can be used for iSCSI host attachment and/or IP-based replication.
IBM strives to make each new model of every storage device more energy efficient than the last.
The new XIV model is no exception. The original XIV, introduced in 2008, consumed 8.4 kVA fully loaded. The XIV Gen 3 model 114 consumed 7.0 kVA. This new model 214 consumes only 5.9 kVA!
It has been almost three years since my now infamous post [Double Drive Failure Debunked: XIV Two Years Later]. Back then, the XIV offered only 1TB and 2TB drives, with rebuild time for 1TB drive of less than 30 minutes, and for 2TB less than 60 minutes.
The new XIV Gen3 software 11.2 release, available for both the 114 and 214 models, can now rebuild a 2TB drive in less than 26 minutes, and a 3TB drive in less than 39 minutes. There is also support specific to Windows Server 2012 including thin provisioning, MSCS, VSS, and Hyper-V. See [Announcement Letter 113-013] for more details.
SmartCloud Storage Access
IBM is the first major storage vendor to offer a product of this kind, so understanding it may be a bit difficult.
The concept is simple. Rather than having end-users having to ask IT every time they need some storage space, IBM created a self-service portal that frees up the IT department to work on more important transformational projects.
This is basically what people can do with "Public Cloud" storage service providers, so basically IBM is now giving you the capability with your "Private Cloud" storage deployment.
Here is the sequence of events. End users point their favorite web browser to the self-service portal, and login using their credentials stored in your Active Directory or LDAP server database.
Once validated, the end-user now can request new storage space, expanding their existing space, or returning the space to the IT department. For new storage requests, users can have a choice of storage classes, -- such as Gold, Silver and Bronze-- defined in the Tivoli Storage Productivity Center (TPC), either stand-alone or in the SmartCloud Virtual Storage Center.
But wait! Do you want to give every end-user a blank check to provision their own storage? Most IT staff are horrified at the thought.
Knowing this, IBM has included an option to put in an approval process, based on the end-user and the amount of capacity requested. The approver can be the cloud administrator, or someone delegated for approvals, known as an environment owner.
For some users, policies may restrict the storage classes as well. For example, Fred can only have Silver or Bronze, but not Gold.
Once the approval is obtained, TPC then issues the appropriate commands to the appropriate SONAS or Storwize V7000 Unified device. SmartCloud Storage Access can do this for thousands of storage devices across dozens of geographically dispersed locations.
Before, the Cloud Admin had to configure storage pools of managed disks, define file systems, dole out file sets to hundreds or thousands of users with hard quotas, and then configure shares based on the protocols required, like CIFS, NFS, HTTPS, etc.
With SmartCloud Storage Access, the Cloud admin still defines the pools and file systems, but then lets the self-service capability of the software to create the file sets, set the quotas and configure shares with the appropriate protocols. This greatly reduces the work on the IT staff, and greatly improves the turn-around time for end-user requests to get exactly what they want, when they need it.
The next time you withdraw money from an ATM machine, fill up your gas tank at the self-service gas station, then serve your own salad at the salad bar and fill up your own soft drink at the fast food restaurant, you will realize and appreciate that SmartCloud Storage Access is a brilliant move for the IT staff.
Cloud administrators, environment owners, and end-users can all use SmartCloud Storage Access to monitor and report on storage usage.
