Before dinner, I was able to catch up with my colleagues from across the pond. Here I am pictured with Ola Surowiec, a Power Systems sales specialist from Scotland.
The dinner was set up as self-service buffet style, with choices of European, Asian, and Middle Eastern cuisine. This is largely the heritage of the Ottoman empire to provide a fusion of flavors from its neighbors.
The city of Istanbul is considered the border between Europe and Asia, with one side of the city on the "European" side, and the other side of the Bosphorus strait being the "Asian" side.
With a population of over 14 million, Istanbul forms one of the largest urban agglomerations in Europe, second largest in the Middle East and the third-largest city in the world by population within its city limits.
The entertainment started with two [belly dancers], one male and one female. (IBM is an equal opportunity employer!) For those not familiar with this particular form of performance art, it is improvised folk dances based on torso articulation and abdominal movements.
I have seen dancers before in Egypt, the country that most people associate with the origin of belly dancing, but the Turkish version is considered more energetic and athletic. Certainly both of our dancers were quite flexible.
This was followed by a live cover band that played the latest English-language hits. Several Americans at the table asked "Wait? We come all the way to Turkey and the local band sings the songs in English?"
In the corner, attendees were invited to dress up as their favorite sultan to take photograph. Here for example, are some of the members of the STU event team. Mo McCullough, Don Meyer, Marlin Maddy, Glenn Anderson and Alex Abderrazag pose with two lovely local ladies in full costume.
The word "sultan" derives from the Arabic word meaning "strength", "authority" or "power". Sultans ruled the Turkish empire from 1299 to 1922.
The [Topkapi palace], where I visited earlier in the week, contains clothing on display of the sultans and princes from the second half of the 15th century to the early 20th century.
Last week, I opined that Monday's IDC announcement "IBM #1 in combined disk and tape storage hardwaresales for 2006" was in part because of a resurgence of interest in tape, with four specific examples. There was a lot of reaction and reflection fromboth sides.
On the one side...
EMC blogger Mark Twomey at Storagezilla admits that perhapsTape Isn't Dead after all,is perhaps the best place to put long-term archive data, but not for backup? EMC's "creative marketing types" put out this Fun With Tape video that I found amusing. (It asks for a first name,last name, and e-mail address, which are then embedded into the resulting video itself, and perhaps forwarded to your nearest EMC sales rep, so answer according to your wishes for privacy).
The "mummy wrapped in tape media" seems to be a common theme, and shows up again in LiveVault'svideo with John Cleese, which makes the same argument asthe EMC video above, namely: switch your backups from tape to disk because we are a disk-only vendor.
... and on the other side
JWT over at DrunkenData asks Which is greener, disk or tape?Tape is, of course, by a long shot, and an essential part of IBM's Big Green initiative, a project to invest$1US Billion dollars per year for data centers to be more efficient for power and cooling.
Sun/StorageTek blogger Randy Chalfant questions the Death of Tape, and argues thatdisk-only solutions suffer from atrophy.The results he posts from a survey of 200 customers are similar to those we've seen with customers using IBM TotalStorage Productivity Center, our software to help evaluate data usage, and identify misuse, in your data center.
To my readers in the USA, United Kingdom, Ireland, South Africa, China and Japan, and a few other countries, Happy Father's Day!
Wrapping up this week's theme on Cloud Computing, I finish with an IBM announcement for two new products to help clients build private cloud environments from their existing Service Oriented Architecture (SOA) deployments.
IBM WebSphere CloudBurst Appliance -- a new hardware appliance that provides access to software virtual images and patterns that can be used as is or easily customized, and then securely deployed, managed and maintained in a private cloud.
IBM WebSphere Application Server Hypervisor Edition -- a version of IBM WebSphere Application Server software optimized to run in a virtualized hardware server environments such as VMware, and comes preloaded in WebSphere Cloudburst.
With more than 7,000 customer implementations worldwide, IBM is the SOA market leader. Of course, both of these products above can be used with IBM System Storage solutions, including Cloud-Optimized Storage offerings like Grid Medical Archive Solution (GMAS), Grid Access Manager software, Scale-Out File Services (SoFS), and the IBM XIV disk system.
IBM is part of the "Cloud Computing 5" major vendors pushing the envelope (the other four are Google, Microsoft, Amazon and Yahoo). In fact, IBM has a number of initiatives that allow customers to leverage IBM software in a cloud. IBM is working in collaboration with Amazon Web Services (AWS), a subsidiary of Amazon.com, Inc. to make IBM software available in the Amazon Elastic Compute Cloud (Amazon EC2). WebSphere sMash, Informix Dynamic Server, DB2, and WebSphere Portal with Lotus Web Content Management Standard Edition are available today through a "pay as you go" model for both development and production instances. In addition to those products, IBM is also announcing the availability of IBM Mashup Center and Lotus Forms Turbo for development and test use in Amazon EC2, and intends to add WebSphere Application Server and WebSphere eXtreme Scale to these offerings.
For more about IBM's leadership in Cloud Computing, see the IBM [Press Release].
Continuing this week's theme on Storage Area Networks, today I thought I would talkabout the various terms we use for our equipment.
One area of confusion are the adjectives "entry-level", "midrange" and "enterprise-class".What do these mean? Well, as in the case of disk and tape, these three are all relative terms that are a combination of "small, medium, large" as well as "good, better, best".
Entry-level switches are typically only a maximum of 8-16 ports.Ports can connect the switch to a server, a storage device, or another switch.These are sometimes called "edge" switches, as they might be found in the mostremote sections of an office campus, remote branches, or other isolated areasoutside the primary data center.
Midrange switches typically have a maximum of 32-64 ports.More ports on a single switch means fewer switches (and fewer cables) to manage.
These are called "directors" to distinguish them from entry-level and midrange offerings.Directors have a maximum of 140-528 ports, and because so many devices or switches can beconnected to them, they need to be extremely reliable. Directors are designed for 24x7operation, with the ability to make most upgrades and configuration changes while the boxis running (often referred to as "non-disruptive upgrades"). Availability is typically better than "five nines", or 99.999 percent, which means that the box will be up 99.999 percent of the time, or conversely, will be down lessthan 5 minutes per year.
If you are asking yourself "which size is right for my company?" or "is my company big enoughfor a director?" you are asking the wrong questions! Instead, determine a SAN configurationthat meets your workload, and then decide the components for that design.
McData coined a phrase called "core/edge" design that is considered today as "Best Practice" throughout the industry.A good write-up can be found here at SearchStorage.com. Basically, you put your big beefy "core" directors in the center of the room, and then surround it with midrange switches, that then these connect to "edge" switches, that then connect to the servers and storage near them. As you grow, this design can easilyscale to grow with you.
So, if you need help implementing a SAN for the first time, or upgrading the one you have,call IBM, we can help!
Well, it's Tuesday again, and you know what that means! IBM Announcements!
Starting today, April 1, 2014, the IBM Executive Briefing Centers (EBC) are adopting a new self-hosted model. In the past, each briefing was assigned a "Briefing Host", a member of the EBC staff, who acted as [master of ceremonies] for the day (or more) for the clients. At some locations, if there were three rooms, there would be three or more briefing hosts so that concurrent briefings could be held.
However, the method does not scale. Having a person per briefing means that you are limited to the number of total concurrent briefings. Inspired by self-service provisioning and scalability of the Cloud, IBM has adopted a new methodology.
In the new model, the visiting client rep, sales rep, or IBM Business Partner will be handed instructions and a map. This will include the agenda, the schedule, biographies of each speaker, the locations of the nearest restrooms, and so on.
I can take partial credit for the idea. In 2012, I made the analogy that having briefing centers at each development lab made a lot of sense, because it allowed clients to interact directly with the engineers and executives that made development decisions. I also made the analogy that having a fully-staffed EBC was like a fire department, whether you have five briefings per month, or fifty, you need a team that is ready, staying abreast of the latest technological changes.
In my post, [Like animals in the zoo], I argued there are two kinds of zoos, the self-guided kind, where visitors are handed a map, versus the docent-guided kind, where a member of the zoo staff introduces you to each animal.
The EBC briefing hosts in this analogy were the docents, and the animals that people came to visit were the engineers and executives.
As for the fire department, IBM management flipped the analogy around. They argued that many smaller communities had "volunteer fire departments", eliminating the need to keep full-time employees doing nothing but playing cards and sliding down brass poles in between fire fighting sessions. When a fire happens, phones calls are made, and this will help get everyone notified to get involved.
In my past 28 years at IBM, I have to say that you know you have good analogies when they can be used in both directions. The zoo analogy was used to prevent management from consolidating all of the EBC staff to Austin, TX. The fire department analogy helped us keep all of our lab equipment to run demonstrations.
The new self-hosted model will address both scheduling and scalability issues. We often had two-day and three-day briefings, and scheduling the rooms, and the briefing managers, based on their availability, was quite challenging.
There are three advantages to the new method:
A coordinator will merely assign rooms, no longer worrying if a briefing host is available for those days. Now, each EBC location can run at full capacity, limited only by real estate and floor space.
Subject matter experts, like myself, that often did double-duty serving as briefing hosts as needed, will have more free time. I personally will be doing more "outbound briefings" to attend conferences and visit clients at their location, eliminating the time I need to be in Tucson to host "inbound" briefings.
The awkward silence that happens when the client rep, sales or IBM Business Partner invites all the clients and presenters, but forgets to invite the briefing host, is completely eliminated.
In his blog, Paul Gillin agrees with Time Magazine's Person of the Year choice of "all of us", those of us who use the World Wide Web to do business or have fun, and to those who contribute to the internet by creating content, such as people who blog or create websites.
So, in continuing my theme this week to recap the best and worst of last year, I list my personal "tech highlights" of 2006.
Programming my Tivo Remotely.
Last September, I realized on a 3-week business trip that I had not programmed my Tivo to record the premieres of each of the new season's television shows. If you miss the first few weeks, it might be difficult to make sense of the rest of the season. Fortunately, I was able to program my Tivo remotely through the internet.
Purchasing TV shows on iTunes
Despite this, I had a repeat episode of "House" record instead of a new episode of
Still unable to make sense of what was going on in the TV show "Heroes", I was able to read the "wiki" which explained all the subtle imagery and background implied.
Using Linux to rescue lost Windows data
My disk drive failed on my laptop, and although I had most of my data backed up with Tivoli Storage Manager prior to my business trip, I had some files that I acquired or updated during the business trip. Thankfully, there are Linux "LiveCD" images that allow you to access your Windows files. You boot these LiveCD images from your CD drive, so there is no installation of Linux on the hard drive itself. If you travel as much as I do, consider bringing along some Linux CDs to get you out of trouble.
Connecting my home entertainment system to my Mac
I now have an 802.1g (54Mb) wireless hub which allows my Tivo to connect wirelessly to the internet to get daily updates, but also allows me to play all my music stored on my Mac through my home entertainment system, and I can also listen to thousands of radio stations through "Live365.com". My favorite station is "Depeche Mode Inspired" which plays songs by Depeche Mode, as well as cover versions by a variety of others.
Learning to Blog
Believe it or not, there is a right way and a wrong way to blog, and this year has been a good learning experience. IBM has a fairly healthy blogging policy, but nonetheless, say the wrong thing and I could be in serious trouble. Fortunately, that hasn't happened, and I am glad to see a fairly open exchange of ideas among the set of bloggers that discuss storage issues.
Building a Snowman in Second Life
I have been a member of Second Life now since November, but it wasn't until I entered a competition to build avirtual snowman last week that the potential of this new interface became obvious to me. There is still lots to learn, but at least now I see value in spending more time and effort learning more about it.
Getting an all-in-one printer/scanner to work with both my Mac and IBM PC
I didn't think it could be done, but here it is, my all-in-one Printer/Scanner works correctly, seemlessly, from both my Windows PC and my Mac Mini, and I have it on my home network so my laptop can use it also, wirelessly!
Using Google Language Tools to translate materials to Portuguese
I speak several languages, enough to order food in restaurants and to get around through various modes of transportation, but translation for a technical audience is more challenging. A class we normally conduct in pure English was taken to Sao Paulo, Brazil, and although most students know some amount of English, we thought it would be good to translate the test questions to Brazillian Portuguese. I took the questions and ran them through a number of translation services websites, and had local IBMers review the results. The winner was Google language tools, which required hardly any edits to the generated text. The class was a big success.
Digital Cameras and CD Burners
As I travelled from Brazil to Bolivia last August, I met a young back-packer who was on her way to Peru, but was staying in La Paz for a few days. We had a great time together, and I was able to transfer the digital photos from my Canon PowerShot digital camera into my laptop and burn her a CD to take with her to Peru.
Painting my Dining Room table
After Halloween, I accidently left my pumpkin jack-o-lantern on my kitchen table as I left for a trip, and when I got back, it had decomposed and left a terrible stain on the wood surface. After sanding the table, I determined that the best course of action was just to paint the surface. I could have just painted it a solid color, or maybe a faux finish with two colors, but instead, chose to copy a famous painting, "Le Cafe" by Alberto Magnelli. I was able to scan this into my computer, resize it, and then project the image onto my table, to then outline the image and paint. I know I would not have been able to do this free-hand.
I am sure there are other triumphs I had throughout the year, but these are the first the come to mind.
This week I was in Palm Springs in meetings with clients, prospects, business partners and IBM sales reps.
Tuesday consisted of "outdoor meetings", but the high winds caused some people to arrive late, and others to land in the various sand traps and water hazards. A "welcome reception" event allowed everyone to socialize and get to know the IBM experts and executives. Two of my colleagues, Mike Stanek and Dave Wyatt, were with me also in Australia last week, and so the three of us were discussing recovery from jet lag.
Wednesday was organized as a main tent event, where everyone met into one large room to hear our strategy,latest set of offerings, and customer testimonials. This was done indoors, of course, which was a good thing as the winds were now gusting up to 50 miles per hour, knocking over windmills and making the local news.
Here's a quick sample from the testimonials:
An insurance company virtualized their IBM DS8000, DS4000, ESS 800 and EMC DMX3 high-end disk with theIBM System Storage SAN Volume Controller and got higher availability and performance. Data migrationefforts that used to take six(6) hours of admin time now took less than one hour, and with no system downtime.They have a total of 350TB virtualized under SVC now, but plan to extend this for a variety of other projects.
A bank presented their success using "Global Mirror" (IBM's asynchronous two-site replication disk mirroring capability).Their previous "business continuity" plan was called 2-20-24 for 2 sites that were 20 miles apart and recovery time objective (RTO) of 24 hours. With the events of Hurricane Katrina, this was considered inadequate, and a new2-200-6 plan was requested, across 200 miles with a recovery time objective of only 6 hours. The chose to deploythis one application at a time, to learn and grow by experience in each phase. They started with Microsoft Exchange e-mail application running under VMware on BladeCenter servers, and wereable to recover remotely within 1 hour. They are now looking to refine and automate the recovery process, perhapswith IBM TotalStorage Productivity Center for Replication and Geographically Dispersed Open Clusters (GDOC).
A healthcare provider presented their success with tiered storage, managing a 475TB mix of IBM DS8000, DS6000,DS4000 and HP EVA disk arrays. The key was having centralized storage management from IBM, which allowedthem to shrink provisioning time from 3 weeks average, to now 96% of their storage provisioning requests are completedin less than 1 week. Moving data between storage tiers was non-disruptive, and the significantcosts savings greatly justified the change in "mindset" that required some training on the new environment.
Thursday we offered a series of "workshops" on specific topics. These were interactive sessions to discuss installation, design and deployment of various solutions. The event ended early enough so that people couldreturn home, or go to the practice range, which reminded me of this inspiring video on How to play golf as well as Tiger Woods.
The event got great reviews, and I look forward to the next one. Until then, enjoy the weekend!
I returned safely from my trip to Tulsa, Oklahoma.
(A special shout-out to Shannon at [In The Raw] sushi restaurant, and my new friends I met at the rooftop of [the Mayo]!)
Last week I was in Auckland, New Zealand teaching Top Gun class. Top Gun teaches IBM Business Partners and sales reps how to sell our products, services, and solutions. I have been teaching Top Gun classes around the world since 1998.
(Why didn't I post sooner? Because IBM's developerWorks was getting an exciting upgrade to IBM Connections 4.0, and bloggers like me have to wait for the conversion to complete!)
While many of my trips in the USA involve traveling alone, that is not the case for Top Gun classes. Our class manager, Joe Ebidia, brought his wife Karen. Our class administrator is Hyein (Hyein is a Korean name that rhymes with rain). In addition to some local instructors, I am joined by my IBM USA colleagues Scott McPeek (Tivoli Storage) and Vic Peltz (Disk/Replication/Competitive Sales).
The rest of the teach team arrived a day or two early to adjust to jet lag. I, on the other hand, got off the plane Monday at 6am, and had a business meeting that same morning with GTS architects from Wellington.
Clockwise from left: Karen is vegetarian, and had some pasta with tomato sauce. Hyein had a lamb burger. Joe had flounder. I had salmon risotto. Yum!
(To those asking why I have only the bellies of Karen and Joe in the picture, I was focused on taking picture of the food.)
After setting up the classroom, we took a ferry over to [Devonport], a charming seaside village just minutes across the bay from Auckland. The ferry boats were close the the Central Business District our [Stamford Plaza hotel] was in, and they run every 30 minutes.
The four of us walked up to the top of Mt. Victoria to see the views of the city. I highly recommend this! Once you get to Devonport, you can walk along the streets to see all the cute shops, or enjoy the parks and natural beauty. I had [done this before], but it is always worth doing again!
The class is four days long. I had six presentations. Here were the first three:
Selling IBM Storwize V7000 and V7000 Unified. Scott McPeek had already covered SAN Volume Controller (SVC), so it was easy to explain the Storwize V7000. For the V7000 Unified, I went into more detail of the file-based protocols and features, paving the way for Vic's "Selling SONAS" later in the week.
Selling IBM Storwize V3700. Having covered the SVC and Storwize V7000, my presentation on the Storwize V3700 focuses more on the positioning of when to sell which product for particular workloads.
Understanding IBM's Big Four Initiatives. This was an interesting request. I was asked to cover Social, Mobile, Analytics and Cloud (what we internally call SMAC) from a storage perspective. Social included Social Media, Social Networking and Social Business. Mobile focused on IBM's Mobile First campaign. Analytics included big data, Hadoop, and our various solutions for performing analytics. Cloud included IBM's Cloud Computing Reference Architecture (CCRA), IBM SmartCloud Enterprise storage, our Backup and Archive clouds, and the new SmartCloud Storage portfolio.
I will save the rest of the week for the next post!
Tuesday is always good for announcements. Today, Gartner, Inc. announced that IBM has taken over HP in its climb to the top. I'll quote directly from today's press release:
STAMFORD, Conn., March 6, 2007 — Worldwide external controller-based (ECB) disk storage revenue totaled $15.2 billion in 2006, a 4.1 percent increase over 2005 revenue of $14.6 billion, according to Gartner, Inc.IBM overtook Hewlett-Packard for the No. 2 position in 2006 (see Table 1). IBM’s worldwide ECB market share increased to 15.8 percent, while HP’s market share dropped to 13.1 percent.
IBM beat HP both in 4Q06, as well as 2006 full year.You can read more about it from Gartner Dataquest report “Market Share: Disk Array Storage, All Regions, All Countries, 1Q05-4Q06" on their website. (Note: non-IBMers might need an account with Gartner to access this, not sure)
The focus was on external controller-based disk, not external controller-less SCSI/SAS disk, not disk arrays posing as virtual tape libraries, nor any disk sold inside HP, Sun, IBM or Dell servers. This is to compare with disk-only vendors such as EMC and HDS. The revenues reflect hardware only, including hardware-related parts of financial leases and managed services. Revenues from optional priced software features such as multi-pathing drivers, management software, or advanced copy services were excluded.I discussed these types of analyst reports back in blog post last September: Space Race Heats Up.
These marketshare numbers are based on revenues, not units or terabytes. When a box gets sold, the revenue was counted toward the vendor that sold it, not the manufacturer that built it. In this last report:
When Dell sells an EMC box, it gets counted as Dell. When Fujitsu Siemens sells an EMC box, it gets counted as "Other".
When HP sells an HDS box, it gets counted as HP. When Sun sells the HDS box, it gets counted as Sun.
When IBM sells its System Storage N series (from the OEM agreement with NetApp), it gets counted as IBM. Both IBM and NetApp experienced growth in the NAS/unified storage arena.
It's still cold here in the Washington DC area, but at least good news like this helps warm me up!
A Brief History of SVC and Storwize Family: What, How and Why?
Fellow IBM Master Inventor [and blogger] Barry Whyte gave an excellent session on the past 10 years of development history for IBM SAN Volume Controller and the rest of the Storwize Family based on its binary code. The SAN Volume Controller represents the start of a movement, what is now called "Software-Defined Storage", with a layer of abstraction that completely hides the differences between different back-end devices. The Storwize family is the most successful Software-defined Storage solution in the IT industry!
IBM Cloud Storage Architectures
IBM Clod Barrera presented an updated version of his "Cloud Storage Architecture" pitch from a technical and strategic viewpoint. From 2011 to 2015, external storage spend is increasing 25 percent for public cloud, and 17 percent for private cloud deployments, and that is not including all of the Do-it-yourselfers like Facebook who build their own storage devices from piece parts.
This year, Clod has expanded his "Cloud Storage Taxonomy" to six different categories:
OLTP/transactional, typically block-based
General purpose storage
Ephemeral storage that exists only while a specific virtual machine (VM) is running
Analytics, which tends to be more sequential than random in I/O pattern
IBM is a platinum sponsor of OpenStack, and is proud to have hundreds of contributors assigned to improve this open source initiative.
IBM Linear Tape File System - Enterprise Edition
IBM Ed Childers presented the latest announcement on Linear Tape File System [LTFS]. For a quick recap, IBM first introduced LTFS Standard Drive Edition [LTFS-SDE] in April 2010, which allowed workstations attached to single tape drives to use cartridges much like USB memory sticks. Then, IBM introduced LTFS Library Edition [LTFS-LE] which allows an entire tape library to be mounted as a file system, with each resident tape cartridge listed as a sub-directory.
Now, IBM has LTFS Enterprise Edition, which combines disk-based General Parallel File System [GPFS] with LTFS-LE, resulting in a combined hybrid disk-and-tape file system.
To provide a client's perspective, Konstantin Arnold with Biozentrum, the Life Sciences Research department of the University of Basel, Switzerland and SIB Swiss Institute of Bioinformatics presented some shocking information on their data growth. Biozentrum studies 3D protein folding, with information from the Worldwide Protein Data Bank [PDB] and [UniProt], which combines protein information from Swiss-Prot with manually annotations and TrEMBL computationally analyzed and automatically annotated entries.
Combining lab data, proteomics, deep-sequencing, imaging and high-content analysis, their storage requirements has grown exponentially, from less than 50 TB in 2009, to over 350TB in 2013. With the need to have such a large repository of unstructured data, it made sense to use LTFS-EE for this project!
IBMers presented the use of SAN Volume Controller (SVC) in a "stretch cluster" for a production environment at a bank in the Middle East. Before going into the technical details of the solution, they explained the challenges of running a bank under Sharia law. For example, Sharia law does not allow charging interest rates on borrowed money, but banks can charge fees for services. Debit cards are automatically denied at shops that are "black-listed" such as liquor stores, that are not consistent with the precepts of the Islamic religion.
The SVC implementation was rather straight-forward. IBM has offered Stretch Cluster since 2009 with version 5.1, but it only gained popularity years later when VMware pointed out that this can be used for datacenter to datacenter vMotion activity. The IBM team tested this out with a short 500 meter distance locally, before stretching it out to two locations now implemented. They have three SVC nodes managing 60TB of managed disk capacity at each data center, made up from a mix of DS8870, Storwize V7000 and DS3950 disk systems.
To demonstrate the robustness of the solution, the client requested that the IBM team demonstrate various recovery scenarios while running live in production mode! As you would expect, IBM SVC successfully handled every one.
IBM Cloud Storage with OpenStack and IBM System Storage
IBM Michael Factor presented this overview of OpenStack, and how IBM already supports various aspects of the open source initiative with products like SAN Volume Controller, XIV, and Storwize V7000.
This was the best overview of OpenStack I had heard. IBM is a platinum sponsor of this open source initiative, managed by the [OpenStack Foundation]. In traditional open source fashion, bi-annual releases are given alphabetically-ascending names. The last release was named Folsom, the current release is Grizzly, and the next release planned will be named Havana.
OpenStack is designed to manage your data center or cloud across four capabilities: Compute, Network, Storage and Shared Services. For Compute, the "Nova" project focuses on managing running VM instances, and "Glance" manages VM images that can be launched. The "Networking" project focuses on providing network connectivity. This was formerly called "Quantum", but Quantum (the company) felt there might be some confusion, so it was renamed to just "Networking".
For Storage, there are two projects, "Cinder" and "Swift". Cinder refers to persistent, external block storage, accessible via iSCSI or Fibre Channel. IBM's SAN Volume Controller, XIV and Storwize V7000 already support the Cinder API interface. Swift is focused on "object storage", which can provide an alternative way of storing information for cloud-based applications. SNIA's Cloud Data Management Interface (CDMI) is working with OpenStack to bring object storage into the mainstream.
With the Cinder API, applications can create volumes, take snapshots, set quotas, and attach these volumes to VM instances.
I realize there is a big time gap between this post and my last. Where have I been? "Where haven't I been?"... might be the better question! After my week at Edge, I flew from Las Vegas to Sao Paulo, Brazil where various protests delayed my departure, then visited clients in the Midwestern USA, then London to watch a bit of tennis. From there, I flew to Athens, Greece (and yes, more protests!), took some overdue time-off on the beach on various Greek islands, then taught a Storage Top Gun class in Bangalore, India. So, yes, I have been quite busy. I will try to catch up on typing up all my notes from the IBM Edge conference over the next few weeks!
From a technology-oriented to a service-oriented approach to IT management
Companies are challenged with shifting from a technology/resource-oriented to a service-oriented approach to IT management. This involves new processes, a new reportingstructure for the IT staff, new tools and technologies, and new data to be captured.A top-down approach is recommended for large organizations, but a bottom-up approachmight be easier to implement for small and medium sized businesses.
IT service management architecture and autonomic computing
IBM has been promoting the concept of Autonomic Computing since 2001. A self-managed resource can have an autonomic manager with sensor and effector. The sensor is used to monitor status, a knowledge basecan analyze and plan for appropriate modifications, and execute these through theeffector. The Autonomic Computing Reference Architecture (ACRA) aligns with the Information Technology Service Management (ITSM) model well, with the CMDB acting asthe knowledge base for the autonomic managers. See my earlier post[Self tuning guitars and storage].
Evolving standards for IT service management
Changes to the IT infrastructure must be closely managed to avoid disruptions.IT organizations recognize that standards-based solutions enable interoperability,with less risk, to connect internal and external applications. Standards can be formally developed by standards bodies like ISO, IETF, W3C, OASIS, and DMTF; or be de facto standards that become widely used by companies, which can then laterbe adopted by standards bodies. SML and SDD are emerging standards that are incompatible with the current set of Web Services-based protocols, like WSDM, but work isunderway to try to determine a unifying standard to support all of these under ITSM.
Prospects for simplifying ITSM-based management through self-managing resources
An ideal computing system would take over a great deal of its own management.Today's IT systems are brittle, difficult to understand, and dangerous to change.The savings from automating some tasks are dwarfed by the irreducible costs of humandecision making, agreements and approvals built in formal processes. A true self-managing, scalable IT system would consist of a number of nearly-identical boxes,with a web interface to define high-level policies and provide information on utilization and performance. As the system needs to expand, it can automatically place the order. When the new boxes arrive, they are placed and connectedinto the data center, and the system configures and provisions them appropriately.
IT Autopilot: A flexible IT service management and deliver platform for smalland medium business
Using an airplane analogy, the pilot performs manual steps to get the plane safelyoff the ground, then turns it over to the autopilot for normal operations. The ITAutopilot intends to do this for IT service management in small and medium business (SMB)that may not have a large dedicated IT staff, using an SOA approach that isloosely coupled, stateless, and adhering to Web Services standards. The IT Autopilotemploys workflow-based controls, the autonomic computing MAPE model, and customizedpolicies to address SMB requirements. It could be deployed as an appliance, similarto IBM System Storage Productivity Center.
Over 4,000 issues of your favorite magazine now sit, ready for you to search and savor, on an 80GB incredibly lightweight and travel-friendly drive. This high-performance, brushed-aluminum Hard Drive measures only 3x5-inch and can easily fit inside a purse or briefcase so show it off to your tech-savvy friends and co-workers. Plus, there is plenty of extra room on the drive for future updates. Simply install The Complete New Yorker Program (installation CD provided), then connect the drive to a USB port on your Computer and have instant access to every article, poem, short story, and cartoon including every advertisement that has appeared in the magazine since 1925.
System Requirements: Windows 2000 or XP, Mac OS X 10.3 or higher, USB 2.0 port, CD-ROM drive, 750 MB of free hard drive space, 1024 x 768 minimum screen Resolution
The 750MB of disk space required on your system probably contains the indexing/metadata search system to find articles by subject, title or author. Linux is not listed, and if 750MB of disk space are required to run the program, then perhaps this system won't work with Linux at all.
The system claims that there is extra room on the disk to ingest future issues of the magazine. I wonder why they didn't put the indexing/metadata search software on the drive itself, so that it would be self-contained, rather than having a separate installation CD.
I think this is a sign of our times. The New Yorker magazine has taken the archives that they keep anyways, and made them available in bulk, in a handy disk drive delivery system. I know several people who keep boxes and boxes of back issues of all kinds of magazines, and this certainly is an improvement.
Last year in Beijing, China, one of my colleagues told me "When it rains here, cabs dry up". Normally, there are enough taxi cabs to handle normal conditions, but when it rains, people who normally walk now want to take a cab instead, and the demand goes up, resulting in being more difficult to find one when you need one.
I'm wrapping up my week here in Chicago, and it snowed yesterday. Cabs were scarce. I walked. Many others walked too, about half with umbrellas to protect themselves against the snowflakes.
Most systems are designed to handle typical average conditions. Taxi cabs in a city, for example, handle typicalamounts of traffic.
IT is different. In many cases, IT infrastructures are designed for the peaks, not the averages. Peaks can be where you need performance the most, and failure to design for peaks can be disastrous. As with any business decision, this represents a trade-off. Design for the average, and suffer through the peaks, or design for the peak, and be over-allocated and under-utilized most of the time otherwise.
The "corporate bloggers" from the various storage vendors often mention their opinions about IBM products. Sometimes, they say something nice, and other times they poke fun. It's good to read the various opinions. Most are well-thought and well-written.
EMC blogger Chuck Hollis has a post about the various categories that industry analyst IDC used for external controller-based disk in their most recentQ4 Storage Scorecard.I agree with Chuck that it is good to have independent analysts that take an objective look across all storage vendors to provide the facts on various makes and models. Both IBM and EMC took marketshare in 4Q, so we cancongratulate ourselves and each other for the efforts needed to make this happen.
Chuck mentions that while EMC and HDS high-end boxes are similar, perhaps IBM's "DS" series is different enough to question putting it in the same "high-end" category. It's not clear if Chuck is poking fun at the fact that theIBM DS family spans multiple categories; or an admission thatthe IBM DS8300 Turbo is faster than the EMC DMX-3 and HDS USP offerings. Perhaps we need a new categorycalled "super high-end"?
IDC doesn't publish their data by price band, but we can infer from the products in each how they decidedwhich products were grouped into which categories. Let's examine the entire IBM DS family in the various categories.
Our newest offering is the IBM System Storage DS3000 series. Some analysts call this category "low end", but IBM prefers using "entry level". These have an attractivelow acquisition price, very easy to set up, and are intended for the Intel and AMD servers, such as IBMBladeCenter, System x, as well as servers from HP and Dell. Disk arrays in this category typically have listprices below $50,000 USD.
Our midrange offering is the IBM System Storage DS4000 series. These are designed for Linux, UNIX and Windows based workloads.Some call these server platforms "open systems", or sometimes "distributed systems". The DS4000 systems are rack-optimized modularunits, providing plenty of options and trade-offs between price and performance for price-sensitive customers.The "high end" model of the DS4000 series is the DS4800, and has very impressive performance characteristics.Disk arrays in this category typically have list prices in the $50,000 to $299,000 USD range.
IBM System Storage DS6000 seriesis one of our enterprise class offerings. DS6000 offers mainframe attachment comparable to what EMC DMX or HDS USP offer for their "enterprise class" or "high end" models, but uses substantially less power and in a much more compact modular rack-optimized packaging. Disk arrays in this category typically have list prices at $300,000 USD and above.
Super High End
Perhaps IBM and EMC can work together to petition IDC to adopt this as a new category, based on performance,rather than list price. Is the storage marketplace ready for a fourth category?As Chuck mentioned on his blog, IBM is #1 for mainframe disk storage, and perhaps it is because the IBM System Storage DS8000 Turbo series does so well on most mainframe workloads. No offering from EMC or HDS meet or beat the SPC benchmarks for the DS8000 Turbo. You can see the results in the Executive Summary or read the Full Report.
Thanks to IBM's innovative Adaptive ReplacementCache algorithm, IBM DS8000 performance shines best handling read-intensive random-access workloads that mainframes do most often. These types of workload are modeled by the SPC-1 benchmark. In cases of write-intensive, sequential processing, the differences are less substantial, as disk arrays from all manufacturers drop down to the native performance capabilities of the 10K and 15K RPM drives.
I'll give you a real example. Not long ago, I waspart of a team to help resolve a performance bottleneck on-site at the customer location. The customer had an interesting "composite application" where data was processed on AIX platform (IBM System p), which passed the data to a Linux partition running on the IBM System z mainframe,which in turn used Java SQL to post updates to a DB2 database on z/OS partition, which then wrote out through FICON adapters to an HDS USP device. IBM and HDS worked together to help the customer figure out why they weregetting disappointing throughput and response times. IBM brought in experts on AIX, TCP/IP, Java, Linux, z/OS and FICON. HDS had their experts too, and tried to improve performance by quadrupling the storage capacity, and spreading the data out across more spindles. That didn't work. As it turns out, HDS disk just couldn't deliver the performance required. The software and mainframe were all well tuned. They replaced the HDS withan IBM DS8000 array, and it met all the service level requirements. Problem solved.
The problem with having this new "super high end" category, of course, is that only IBM plays in it, so it wouldn'toffer the marketplace much of a comparison. For now, we'll just have to settle for being the fastest in the samecategory as EMC DMX and HDS USP.
Storage is a competitive marketplace.Both EMC and HDS are reputable companies that make quality products that attach to IBM System z mainframe servers. Not all workloads are mission-critical or performance-sensitive. For less critical workloads, perhaps you may find EMC or HDS performance is "good enough".
But if performance is important to you, you should consider IBM on your list of vendors for your next purchase decision. Let IBM help you prove it to yourself, running your specific workloads side by side with your existing equipment.
