To avoid overwhelming people with too many features and functions, IBM decided to keep things simple for the first release. Let's take a look:
The base frame (2231-IA3) supports a single collection, from as small as 3.6 TB to as large as 72 TB of usable capacity. You can attach one expansion frame (2231-IS3) that holds two additional collections, 63 TB usable capacity for each collection. Disk capacity is increased in eight-drive (half-drawer) increments of 3.6 TB usable capacity each. A full configured IA system (304 drives, 1 TB raw capacity per drive) provides 198 TB usable capacity.
Of course, that is just the disk side of the solution. Like its predecessor, the IBM System Storage DR550, the IA v1.1 can also attach to external tape storage to store and protect petabytes (PB) of archive data. Hundreds of different IBM and non-IBM tape drives and libraries are supported, so that this can be easily incorporated into existing tape environments.
Each collection can be configured to one of three protection levels: basic, intermediate, and maximum.
Basic protection provides RAID protection of data using standard NFS group/user controls for access to read and write data. This can be useful for databases that need full read/write access. Users can assign expiration dates, but in Basic mode they can delete the data before the expiration date is reached.
Intermediate adds Non-Erasable Non-Rewriteable (NENR) protection against user actions to delete or modify protected data. However, similar to IBM N series "Enterprise SnapLock", intermediate mode allows authorized storage admins to clean up the mess, increase or reduce retention periods, and delete data if it is inadvertently protected. I often refer to this as "training wheels" for those who are trying to work out their workflow procedures before moving on to Maximum mode.
Maximum provides the strictest NENR protection for business, legal, government and industry requirements, comparable to IBM N series "Compliance SnapLock" mode, for data that traditionally were written to WORM optical media. Data cannot be deleted until the retention period ends. Retention periods of individual files and objects can be increased, but not decreased. Retention Hold (often referred to as Litigation Hold) can be used to keep a set of related data even longer in specific circumstances.
You can decide to upgrade your protection after data is written to a collection. Basic mode can be upgraded to Intermediate mode, for example, or Intermediate mode upgraded to Maximum.
To keep things simple, v1.1 of the Information Archive supports only two industry standard protocols: NFS and SSAM API. The NFS option allows standard file commands to read/write data. The System Storage Archive Manager (SSAM) API allows smooth transition from earlier IBM System Storage DR550 deployments. With this announcement, IBM will [discontinue selling the DR550 DR2 models].
As we say here at IBM, "Today is the best day to stop using EMC Centera." For more information, see the
IBM [Announcement Letter].
Continuing my coverage of the 30th annual [Data Center Conference]. here is a recap of Wednesday morning sessions.
A Data Center Perspective on MegaVendors
The morning started with a keynote session. The analyst felt that the eight most strategic or disruptive companies in the past few decades were: IBM, HP, Cisco, SAP, Oracle, Apple and Google. Of these, he focused on the first three, which he termed the "Megavendors", presented in alphabetical order.
Cisco enjoys high-margins and a loyal customer base with Ethernet switch gear. Their new strategy to sell UP and ACROSS the stack moves them into lower-margin business like servers. Their strong agenda with NetApp is not in sync with their partnership with EMC. They recently had senior management turn-over.
HP enjoys a large customer base and is recognized for good design and manufacturing capabilities. Their challenges are mostly organizational, distracted by changes at the top and an untested and ever-changing vision, shifting gears and messages too often. Concerns over the Itanium have not helped them lately.
IBM defies simple description. One can easily recognize Cisco as an "Ethernet Switch" company, HP as a "Printer Company", Oracle as a "Database Company', but you can't say that IBM is an "XYZ" company, as it has re-invented itself successfully over its past 100 years, with a strong focus on client relationships. IBM enjoys high margins, sustainable cost structure, huge resources, a proficient sales team, and is recognized for its innovation with a strong IBM Research division. Their "Smarter Planet" vision has been effective in supporting their individual brands and unlock new opportuties. IBM's focus on growth markets takes advantage of their global reach.
His final advice was to look for "good enough" solutions that are "built for change" rather than "built to last".
Chris works in the Data Center Management and Optimization Services team. IBM owns and/or manages over 425 data centers, representing over 8 million square feet of floorspace. This includes managing 13 million desktops, and 325,000 x86 and UNIX server images, and 1,235 mainframes. IBM is able to pool resources and segment the complexity for flexible resource balancing.
Chris gave an example of a company that selected a Cloud Compute service provided on the East coast a Cloud Storage provider on the West coast, both for offering low rates, but was disappointed in the latency between the two.
Chris asked "How did 5 percent utilization on x86 servers ever become acceptable?" When IBM is brought in to manage a data center, it takes a "No Server Left Behind" approach to reduce risk and allow for a strong focus on end-user transition. Each server is evaluated for its current utilization:
Amazingly, many servers are unused. These are recycled properly.
1 to 19 percent
Workload is virtualized and moved to a new server.
20 to 39 percent
Use IBM's Active Energy Manager to monitor the server.
40 to 59 percent
Add more VMs to this virtualized server.
over 60 percent
Manage the workload balance on this server.
This approach allows IBM to achieve a 60 to 70 percent utilization average on x86 machines, with an ROI payback period of 6 to 18 months, and 2x-3x increase of servers-managed-per-FTE.
Storage is classified using Information Lifecycle Management (ILM) best practices, using automation with pre-defined data placement and movement policies. This allows only 5 percent of data to be on Tier-1, 15 percent on Tier-2, 15 percent on Tier-3, and 65 percent on Tier-4 storage.
Chris recommends adopting IT Service Management, and to shift away from one-off builds, stand-alone apps, and siloed cost management structures, and over to standardization and shared resources.
You may have heard of "Follow-the-sun" but have you heard of "Follow-the-moon"? Global companies often establish "follow-the-sun" for customer service, re-directing phone calls to be handled by people in countries during their respective daytime hours. In the same manner, server and storage virtualization allows workloads to be moved to data centers during night-time hours, following the moon, to take advantage of "free cooling" using outside air instead of computer room air conditioning (CRAC).
Since 2007, IBM has been able to double computer processing capability without increasing energy consumption or carbon gas emissions.
It's Wednesday, Day 3, and I can tell already that the attendees are suffering from "information overload'.
Friday - We landed in Paris, France. I have been to Paris many times, but this was a first for Mo. A croissant cost only 2 Euro, but the young woman behind the counter gave me a look of disgust when I asked for a knife and butter to put on the croissant. If you ever get the chance to have a real French croissant, you will realize you don't need any more butter. If you do attempt to put anything on the croissant, it will disintegrate into a million tiny pieces!
2. Visit Ronda
Saturday - We rented a car and drove to the mountain village of [Ronda, Spain], which is in the heart of the region of Spain called Andalucia. Why Ronda? This was where Mo's uncle was stationed during the war. The town is built on two mountains, connected by a set of bridges. The tallest is "Puente Nuevo", built in the 1700s, which is nearly 400 feet tall. Ronda is also home of Spain's oldest Bull Fighting ring. Bars and restaurants built along the cliff offer some spectacular views. Mo and I shared a "Paella Mixta" for lunch, consisting of yellow rice with bits of chicken and seafood.
3. Soak in European Mineral Waters
Sunday - Most things in Europe are closed on Sunday, so we decided to have a "Spa Day" at the [Gran Hotel Benahavis], in Benahavis, Spain. This lovely hotel is built over a natural mineral waters hot spring, and an underground spa allowed us to relax in the warmth. The spa also had a dry sauna, steam sauna, and ice cold water bath to complete the experience.
4. Climb to the Top of the Rock of Gibraltar
Monday - Technically, Gibraltar is a separate country, but they use British money (Pound Sterling). To get to the top of the rock, we drove across their airport runway, saw the mosque at Point Europa, parked in large parking lot and took the cable car to the top. From there, we climbed a few more steps to see the grand views of Spain and North Africa, while keeping our distance from the infamous monkeys. These [Barbary Macaque] are cute, but can bite or scratch you if you get too close. Afterwards, we had lunch in a pub called the Angry Friar.
5. See Snake Charmers in Morocco
Tuesday - We took a guided tour over to the Kingdom of Morocco. This included a ferry boat ride from Tarifa, Spain to Tangier, Morocco. A bus then took us to the "Kasbah" (the fort), where we got to see snake charmers perform their act. We had an interesting lunch, followed by obligatory "shopping opportunities" for rugs and spices. Back on the bus, we went to a place to go ride camels, see the King's palace, and visit the the Grotto of Hercules. The last stop was to sit back and relax for a nice cup of hot Menthol Tea at Cap Spartel, the northernmost point of Morocco.
6. Hang Out at a Mediterranean Beach
Wednesday - Our last full day in Spain, we decided to have lunch on the beach. This region is referred to as Costa Del Sol. We opted for "Playa de la Rada" in Estepona, Spain. The beach was a bit rocky, the sand was hot and uncomfortable to walk on, and the heat and humidity was just slightly less than the steam sauna at the Gran Hotel Benahavis. We stayed in the shade of our beach-side restaurant and had a lunch of grilled sardines and the local Cruzcampo beer.
7. Visit the World of Coca-Cola
Thursday - we drove to Malaga, Spain, and flew back to the United States. Malaga is famous for celebrities like Ernest Hemingway and Pablo Picaso. We could not get all the way back to Tucson, so we stayed overnight in Atlanta.
Friday - This gave us an opportunity to visit the [World of Coca-Cola], where Mo's cousin had done some recent marketing work in celebration of their 125 year anniversary. This is a museum with a live bottling operation on display, a 4D movie, viewing areas to see commercials from around the world, and free tasting, sampling some of the 105 different soft drink flavors manufactured. I recommend the Tawney Ginger from Tanzania, and the Simba Guarana from Brazil. I did not care for the Apple-and-Carrot soda from Japan.
8. See a Manta Ray Up Close
Our discount combo tickets included a visit to the [Georgia Aquarium] next door. Mo can't scuba-dive, but she got stung by a ray when she was a kid, and wanted to show me a big Manta Ray up close. The aquarium was quite good, divided up into separate exhibits, including interactive touch-the-fish areas for the kids, Beluga whales, Jellyfish, Seahorses, and a moving sidewalk that takes you underneath the sea life.
I would like to thank Delta Air Lines for letting Mo and I take this trip using frequent flyer miles, Hertz Rental Cars for offering a sweet deal on a tiny Hyundai i20 car, the Gran Hotel Benahavis for their hospitality, and the incredibly warm and helpful people of Atlanta. I am glad that my language skills in French, Spanish and Arabic came in quite handy!
In this case, it is not chess pieces, but FUD being slung around like mud between vendors. EMC blogger Chuck Hollis' post [Products vs. Features] correctly pointsout that IBM has invented most nearly everything useful in IT, and sadly a few things we wish we hadn't.Gene Amdahl, who left IBM to start his own company, is credited for coining the phrase describing IBM'sinnovative sales techniques. Wikipedia has a nice write up on the history of[Fear, Uncertainty and Doubt(FUD)].
Nowadays, when you hear "FUD" most storage administrators immediately think of EMC, who have taken this method to anew level of art-form. Take for example two EMC entries from fellow blogger BarryB, on his Storage Anarchist blog:[Not Dead Yet, andPushing Daisies].The first is a reference to a funny scene from a Monty Python movie, and the second one is referring to a terriblenew television program called "Pushing Daisies". (In this show, the main character can bring a dead personback to life for sixty seconds, just long enough to ask a few questions on behalf of his detective friend. He must touch the person again within 60 seconds, or someone else randomly dies instead. I amnot a fan of this concept, and found it a bit morbid and creepy. But I digress.)
It is true I was on vacation the past two weeks, but this was group travel I booked over six months ago before we had the exact dates lined up for our various announcements, and not a last-minute celebration of my recent new job assignment. I got all my assignments for this announcement turned in before leaving for my trip. I never thought of checking with fellow IBM blogger BarryW to make sure that we don't have overlapping vacation schedules, leaving the "blogosphere" unmanned, so to speak, but it is not a bad idea. Fortunately, our IBM PR team was able to make their rebuttal through other means. You can read the recap on Techworld [Marketing Wars by Proxy].
Several astute readers on my blog, however, requested that I add my two cents. Let's take a look at some of BarryB's comments:
...most DS8300's are to this day most frequently bundled as "free" storage with IBM mainframe and server sales.
We just shipped our 15,000th box, so for this absurd statement to be true, more than half would have to be given away as part of a server-and-storage deal?Actually, about a third of our DS8000 sales are sold with servers in the same bundle, and while we do provide discounts from the official list price, that is not the same as "free". The other two thirds are sold into accounts to be used with the existing servers already deployed. So BarryB, your math doesn't work out. (Perhaps you've been taking Hitachi math lessons???)
It is interesting however, that when we do a 4-year TCO comparison, between a normally-discounted DS8000 versus free EMC DMX4 hardware, IBM still has the lower cost, given that most of the price-gouging from EMC happens after the initial sale, through software features, annual Powerpath renewals and MES upgrades. If you are an EMC customer, and you are planning to add more capacity to your DMX, ask EMC to charge you no more than what you originally paid on a dollar-per-GB basis for the initial capacity. That's only fair, right?
...No thin provisioning, or even a commitment to thin provisioning. Just crickets. (Celerra support since Jan 2006...
EMC DMX does not have thin provisioning available today either, so BarryB brings up Celerra, their NAS box? IBM System Storage N series NAS box also has thin provisioning, so if you want thin provisioning you can buy a NAS box from EMC or IBM. Thin provisioning makes sense using NAS protocols, as there are actual commands to "delete a file" that can then free up the related blocks in a thin-provisioned environment. The only way to do this with block-oriented protocols is to get the OS to notify the storage device that blocks can be freed up. As it turns out, IBM's z/OS has such support, which we developed specifically for our thin-provisioning support in our IBM RAMAC Virtual Array disk systems back in the 1990s.For block-oriented devices on most other operating systems, thin provisioning may not be all that it is cracked up to be.
No SATA drives (only DMX-4 supports native SATA-II drives, since Aug’07)
A few people are confused on this. IBM DS8000 has supported FATA for quite some time now, same slower speeds and higher capacities as SATA, but are technically NOT the same as SATA. FATA are designed to provide better protection against vibrational shock, to improve reliability of the drives. IBM felt that if the data was important enough to put on a high-end system, it should get better-than-SATA treatment. If you really want SATA, try our IBM System Storage N series, DS4000 or DS3000 models.
No RAID 6 (DMX-3 has supported multi-dimensional RAID since Q1’07, DMX-4 since Aug'07, ...
IBM N series supports RAID6, but we called it RAID-DP and that confused some people. Same thing, DP stands for Dual Parity, protecting against a double-disk failure. We also just announced RAID6 on our DS4000 series, by the way.
No 4Gb back-end (USP-V since May '07, DMX-4 since Aug’07)
I found this one odd, since BarryB himself in an earlier post explained why 4Gbps back-end made no difference to DMX4 performance in this post [DMX-4 and Oh So Much More], which I will put into a different color so you can tell it is from a different post:
You may have noticed that there weren't any specific performance claims attributed to the new 4Gb FC back-end. This wasn't an oversight, it is in fact intentional. The reality is that when it comes to massive-cache storage architectures, there really isn't that much of a difference between 2Gb/s transfer speeds and 4Gb/s. Transmit times are really only a tiny portion of I/O overhead, and just don't make that much difference when a massively-cached system is pre-fetching reads, buffering/delaying writes and reordering I/O requests to minimize seek times. Not that 4Gb/s won't help some applications, but most people just won't see any noticeable difference.
In this case, BarryB is right. The IBM DS8000's 2Gbps back-end is not a performance bottleneck. The DS8000 with a 2Gbps back-end is faster than DMX4 with a 4Gbps back-end for business application workloads. EMC doesn't publish SPC benchmarks to deny this, so you will just have to take our word on this.
Still only 1024 maximum disk drives (DMX-3 & 4 support up to 2400 drives, USP-V supports 1152)
I would be curious to see how many customers have more than 1024 drives on any high-end disk array.As we learned back in [Day 2 Storage Symposium], the average DS8100 has 17.4 TB, and DS8300 has 41.5 TB capacity. Using 500GB drives,that's only 83 spindles. Even with 73GB drives, that's 568 spindles. Plenty of room for growth, so I am notconvinced that higher theoretical upper architectural limits are worth discussing here.
Still only two HARD LPARs (partitions) ..., and even IBM’s mid-tier products support more than 2 storage partitions (in this same announcement)
IBM's two LPARs are TWICE what EMC DMX offers. I don't even know why anyone from EMC would bring this up? While EMC is enjoying their success with VMware, the lack the experience to carry this over to their storage lines. Until EMC offers MORE THAN TWO of any kind of partitions on their high-end offerings, there just is no credibility here. As for our "storage partitions" on our DS4000 line, that is an unfortunate mis-understanding of the press release. On the DS4000, the term "storage partition" is really "LUN masking", dividing up only which disks can be accessed by which hosts, and not dividing up any processor or cache capacity. So this is not the same as any LPAR concept on any other system. For example, a DS4000 with 64 partitions can be attached to 64 hosts, or 64 host-clusters like a Windows MSCS environment or AIX HACMP.
No native Ethernet replication or iSCSI support (Symmetrix has had since 2002)
Again, I found this one odd. On another EMC post, [Vigorous Debates],Chad Sakac mentions that only 2% of Symmetrix are sold with IP ports, not sure if this is for Ethernet replication, iSCSI attachment, or both (Again, I will use a different color):
On the Symm business (a huge part of EMC’s business – the IP ports are included on 2% of deals. That’s a fact.
Just because engineer can put a feature or function on a box, doesn't mean there is business sense to do so. I would hate for IBM to invest millions of dollars on native iSCSI support, only to have 2% of our DS8000 boxes sold with that feature. Customers who have DS8000 on FC SANs already deployed can easily add iSCSI support either through their SAN switches, or by fronting the DS8000 with an N series gateway. Most customers looking for native iSCSI are the smaller no-SAN-deployed SMB customers, and for them, we have both the DS3300 and the various N series models to choose from.
Well that's my two cents. The DS8000 series remains a strategic part of the IBM System Storage offering matrix, with continued investment in the development, as well as on-going research that we can leverage throughout the IBM company. I would like to read your thoughts on this, post me a comment below.
Wrapping up my week's coverage of the IBM Pulse 2011 conference, I have had several people ask me to explain IBM's latest initiative, Smarter Computing, which IBM launched this week at this conference. Having led the IT industry through the Centralized Computing era and the Distributed Computing era, IBM is now well-positioned to help companies, governments and non-profit organizations to enter the new Smarter Computing era, focused on insight and discovery.
Thousands of IT professionals
Effiicent, but only the largest companies and governments had them
Millions of office workers
Personal computers (PC)
Innovative, extending the reach to small and medium-sized businesses, but resulted in server sprawl and increased TCO
Billions of people
Smart phones and other handheld devices
Efficient and Innovative, combining the best of centralized and distributed computing
1952 to 1980
1981 to 2010
2011 and beyond
To help clients with this transition, IBM's Smarter Computing initiative has three main components. This is a corporate-wide strategy, with systems, software and services all working together to realize results.
The first component is Big Data. This combines three different sources of data:
Traditional structured data in OLTP databases and OLAP data warehouses, using data management solutions like DB2 and IBM Netezza.
Unstructured data, including text documents, images, audio, and video, processed with massive parallelism using IBM BigInsights and Apache Hadoop.
Real-Time Analytics Processing (RTAP) of incoming data, including video surveillance, social media, RFID chips, smart meters, and traffic control systems, processed with IBM InfoSphere Streams
Of course, Big Data will bring new opportunities on the storage front, which I will save for a future post!
Rather than general purpose IT equipment, we have now the scale and scope to specialize with systems optimized for particular workloads, the second component of the Smarter Computing initiative. Of course, IBM has been delivering integrated stacks of systems, software and services for decades now, but it is important to remind people of this, as IBM now has a spate of competitors all trying to follow IBM's lead in this arena.
As with Big Data, the focus on Optimized Systems has impacted IBM's strategy on storage as well. I'll save that discussion for a future post as well!
I am glad that nearly all of the storage vendors have standardized to a common definition for Cloud, the third component of Smarter Computing, which shows that this concept has matured:
Cloud computing is a pay-per-use model for enabling network access to a pool of computing resources that can be provisioned and released rapidly with minimal management effort or service provider interaction. -- U.S. National Institute of Standards and Technology [nist.gov]
Of course, Cloud is just an evolution of IBM's Service Bureau business of the 1960s and 1970s, renting out time-sharing on mainframe systems, Grid Computing of the 1980s, and Application Service Providers that popped up in the 1990s. While the [butchers, bakers and candlestick makers] that IBM competes against might focus their efforts on just private cloud or just public cloud, IBM recognizes the reality is that different clients will need different solutions. Rather than rip-and-replace, IBM will help clients transition to cloud via inclusive solutions that adopt a hybrid approach:
Traditional enterprise with private cloud deployments, using solutions like IBM CloudBurst, SONAS and Information Archive
Traditional enterprise with public cloud services to handle seasonable peaks, providing offsite resiliency, and solutions for a mobile workforce
Hybrid clouds that blend private and public cloud services, to handle seasonal peak workloads, remote and branch offices
IBM's emphasis on IT Infrastructure Library (ITIL), Tivoli and Maximo products will play well in this space to provide integrated service management across traditional and cloud deployments. This is why IBM decided to launch Smarter Computing initiative at Pulse 2011 conference, the industry's premiere conference on intergrated service management.
The IBM Watson that competed on Jeopardy! is an excellent example of all three components of Smarter Computing at work.
IBM Watson was able to respond to Jeopardy! clues within three seconds, processing a combination of database searches with DB2 and text-mining analytics of unstructured data with IBM BigInsights.
IBM Watson combined servers, software and storage into an integrated supercomputer that was optimized for one particular workload: playing Jeopardy!
IBM Watson used many technologies prevalent in private and public cloud computing systems, storing its data on a modified version of SONAS for storage, using xCat administration tools, networking across 10GbE Ethernet, and massive parallel processing through lots of PowerVM guest images.
Actually, if the title confuses you, it is because it has a double meaning.
Meaning 1: IBM earned almost 100 Billion dollars (USD)
IBM's 2010 [earnings report is now available], for the full year 2010 and the fourth quarter. IBM had $99.9 Billion dollars (USD) in revenue, almost $100 Billion dollars that it had set out as a vision in the 1980s. IBM Storage contributed with 8 percent growth, not bad for a year Dave Barry considers [one of the worst years ever.].
IBM President and CEO Sam Palmisano granted me a chunk of IBM stock in appreciation of my efforts towards the 2010 success! Actually, he gave stock to a whole bunch of IBMers, not just me, and they all deserve it also. Woo hoo!
Meaning 2: IBM is almost 100 years old
That's right, this upcoming June 16, 2011, IBM turns 100 years old. This Centennial date also happens to be my 25th year anniversary working in IBM Storage, which IBM calls joining the Quarter Century Club, or QCC for short. So, I am looking forward to plenty of cake and fireworks on that day!
I am looking forward to a year-long celebration on both counts!
The "Storage Resource Agent" introduced for Linux, AIX and Windows in v4.1 is a lightweight agent, written in native "C" language instead of Java, to avoid all the resources that Java consumes. In this release, it is now supported for HP-UX and Solaris, and adds file level and database level storage resource management (SRM) reporting for all five platforms.
For new customer deployments, this will eliminate all the pain setting up a "Common Agent Manager". The Productivity Center server will send out the agent, the agent collects the data, and can then optionally uninstall itself. In this manner, you always have the latest version of the code collecting the data. For those with Common Agent Manager already installed, you can continue running as is, or slowly transition over to the new lightweight agent methodology.
Full support for IBM XIV Storage System
IBM XIV® Storage System support updated to include provisioning, data path explorer and performance management reporting. Before this release, Productivity Center could only discover and provide rudimentary capacity information for XIV systems. Now you can carve LUNs and monitor XIV disk performance just like you can with most other disk systems.
Storage Area Network (SAN) configuration planning
For those who have both Productivity Center Standard Edition (SE) and Productivity Center for Replication, the SAN Config Planner is now "replication-aware" and will add LUNs to existing copy sessions, or create new copy sessions, and ensure that the devices chosen meet the appropriate criteria.
HyperSwap™ for the IBM AIX® environment
On z/OS mainframes, if you experience an outage on a storage system, Productivity Center for Replication (TPC-R) can automatically swap to the synchronous mirror copy without disruption to the operating system or application. Now, IBM has extended this awesome feature to the AIX platform for high availability in POWER-based server environments.
Detailed Session Reporting for Global Mirror
Before, TPC-R enforced the notion of only one Global Mirror master per storage system. Now, TPC-R v4.2 is capable of supporting multiple Global MIrror sessions, and provide more detailed session reporting for these environments. This can be useful if for some unknown reason the bits are not being shoveled from point A to point B, and you need to do some "problem determination".
SVC Incremental FlashCopy
Productivity Center for Replication now adds support for the "Incremental" feature of SVC FlashCopy. While FlashCopy requests are processed instantaneously, there is background processing required that can consume cycles. Incremental processing keeps track of what changed since the last FlashCopy, and minimizes this behind-the-scenes overhead.
Integrated Distributed Disaster Recovery manager
IBM Tivoli System Automation Application Manager [TSA-AM] can now integrate with TPC-R to provide application-aware disaster recovery capability. This can coordinate between IBM Tivoli System Automation for Multiplatforms [TSA-for-MP], IBM HACMP/PowerHA, as well as other clustering products like Microsoft Cluster Services (MSCS) and Veritas Cluster Services on Solaris. When TSA-AM detects an outage, it can notify Globally Dispersed Parallet Sysplex Distributed Cluster Management (GDPS-DCM) to take action. This integration was actually completed with TPC v4.1 back in April, but got buried deep inside our big storage launch, so I bring it up again as a gentle reminder that IBM offers the best end-to-end management on the planet.
At last month's Storage University, I presented an overview of [Tivoli Storage Productivity Center v4.1]. Many of the questions were along the lines of "When will TPC do xyz?" and all I could answer was "Soon" since I knew they would be delivered with this TPC v4.2 release, but I couldn't provide any more details than that at the time.
EMC Corporation (NYSE:EMC) today announced it has been positioned as a leader in the Forrester Wave™: Enterprise Open Systems Virtual Tape Library (VTL), Q1 2008 by Forrester Research, Inc. (January 31, 2008), an independent market and technology research firm. EMC achieved a position as a leader in the Forrester Wave report on virtual tape libraries based on the largest installed base of the EMC® Disk Library family of systems, its broad ecosystem interoperability. Virtual tape libraries emulate tape drives and work in conjunction with existing backup software applications, enabling fast backup and restoration of data by using high-capacity, low-cost disk drives.
EMC was the first major vendor in the open systems virtual tape library market as it introduced the EMC Disk Library in April 2004 and today is a leading provider of open systems virtual tape solutions, with systems that are designed for businesses and organizations of all sizes.
While the press release implies that "EDL equals VTL", Chuck tries to explain they are in fact very different. Here is an excerpt from his blog post:
Virtual Tape Libraries vs. Disk Libraries
As many of you know, VTLs have been around for a while. They use disk as a cache -- they buffer the incoming backup streams, do some housekeeping and stacking, then turn around and write tape efficiently. When you go to restore, you're usually coming back off of tape, unless the backup image in question is sitting in the disk cache.
Now, there is nothing wrong with the VTL approach, but it was conceived in a time when disks were horribly expensive. It was also pretty clear to many of us that disks were going to be a whole lot cheaper in the near future, and this fundamental assumption wouldn't be valid for much longer.
I kept thinking in terms of disk as a direct target for a backup application. No modifications to the backup application. Native speed of sequential disks for both backup and restore. Tape positioned as a backup to the backup. Use the strengths of the underlying array (e.g. CLARiiON) for performance, availability, management, etc.
We ended up calling the concept a "disk library" to differentiate from the VTLs that had come before it. It was a different value proposition and offering, based on the emergence of lower-cost disk media.
... It's nice to see we're at 1,100+ customers, and still going strong.
For those new to the blogosphere, there is a difference between "Press Releases" as formalcorporate communications versus "Blog Posts" which are informal opinions of the individual blogger, whichmay or may not match exactly the views of their respective employer.As we've learned many times before, one should not treat termslike "first" or "leader" in corporate press releases literally! Let's explore each.
Was EDL the first "open systems" Virtual Tape Library?
This is implied by the Forrester report. Chuck mentions the "VTLs that had came before it" in his blog, and many people are aware that IBM and StorageTek had introduced mainframe-attached VTLs in the 1990s. But what about VTL for "open systems"?
(Hold aside for the moment that IBM System zmainframe is an open system itself, with z/OS certified as a bona fide UNIX operating system by the [the Open Group] standards body. Most analysts and research firms usually refer only to the non-mainframe versions of UNIX and Windows. Alternative definitions for "open systems" can be foundin [Web definitions or Wikipedia]. I will assume Forrester meantnon-mainframe servers.)
IBM announced AIX non-mainframe attachment via SCSI connectivity to the IBM 3494 Virtual Tape Server (VTS) on Feb 16, 1999, with general availability in May 28, 1999. That's nearly FIVE YEARS before the April 2004 introduction of EDL. IBM VTS support for Sun Solaris and Microsoft Windows came shortly thereafter in November 2000, and support for HP-UX a bit later in June 2001. One of my 17 patents is for the software inside the IBM 3494 VTS, so like Chuck, I can takesome pride in the success of a successful product.
(I don't remember if StorageTek, which was subsequently acquired by Sun, had ever supported non-mainframe operating systems with their Virtual Storage Manager[VSM] offering, but if they did, I am sure it was also before EMC.)
Last week, another EMC blogger, BarryB (aka [the Storage Anarchist]),took me to task in comments on my post [IBM now supports 1TB SATA drives]. He felt that IBM should not claim support, given that the software inside the IBM System Storage N series is developed by NetApp. He compared this to the situation of HP and Sun re-badging the HDS USP-V disk system. If someone else wrote the software, BarryB opines, IBM should not claim credit for it. I tried to explain how IBM provides added value and has full-time employees dedicated to N series development and support, butdoubt I have changed his mind.
Why do I bring that up? Because the EMC Disk Library runs OEM software from FalconStor. Basically EMC is assembling a hardware/software solution with components provided from OEM suppliers. Hmmm? Sound familiar? Who is calling the kettle black?
If there is a clear winner here, it is FalconStor itself.Perhaps one of the worst kept industry secrets is that FalconStor software is also used in VTL offerings from Sun, Copan, and IBM, the latter embodied as the [IBM TS7520 Virtualization Engine] offering. If you like the concept of an EDL,but prefer instead one-stop shopping from an "information infrastructure" vendor, IBM can offer the TS7520 along with servers, software and services for a complete end-to-end solution.
Can EMC claim to be "a leader" in Virtual Tape Libraries?
During the measured quarter, IBM shipped its 10 millionth LTO-4 tape drive cartridge to Getty Images, the world's leading creator and distributor of still imagery, footage and multi-media products, as well as a recognized provider of other forms of premium digital content, including music. Getty Images is using the LTO-4 drives as part of a tiered infrastructure of IBM disk and tape solutions that help support the backup needs of their digital imagery;
IBM shipped more than 1,500 Petabytes of tape storage in Q3'07 alone;
During Q3'07, IBM shipped the 10,000th IBM System Storage TS3500 Tape Library. The TS3500 is a highly scalable tape library with support from 1 to 192 tape drives and up to 6,400 cartridge slots for open system, mainframe and virtual tape system attachment.
Let's take a look at the numbers. IBM has sold over 5,400 virtual tape libraries. Sun/STK has sold over 4,000 virtual tape libraries. Both are drastically more than the 1,100 mentioned in Chuck's post. Does IDC recognize EMC in third place? No, EMC chooses instead to declare EDL as disk arrays (probably toprop up their IDC "Disk Tracker" numbers), so they don't even earn an honorable mention under the virtual tape librarycategory. This of course includes the number of mainframe-attached models from IBM and Sun/STK. So, if EMC did call these tape systems instead, they might showup in third place, and as such EMC could claim to be "a leader" in much the same way an athlete can claim to be an "Olympic medalist" winning the bronze for third place. (If you limit thecount to just the FalconStor-based models from IBM, EMC, Sun and Copan, then EMC moves up to first or second, but then press release titles like "EMC a Leader in FalconStor-based non-mainframe Virtual Tape Libraries" can get too confusing.)
Chuck, if you are reading this, I feel you have every right to celebrate your involvement with the EDL. Despite having common software and hardware components, both IBM and EMC can rightfully declare their own unique value-add through their respective VTL offerings. Like the IBM N series, the EMC Disk Library is not diminished by the fact the software was written by someone else. BarryB might disagree.
Well, this week I am in Maryland, just outside of Washington DC. It's a bit cold here.
Robin Harris over at StorageMojo put out this Open Letter to Seagate, Hitachi GST, EMC, HP, NetApp, IBM and Sun about the results of two academic papers, one from Google, and another from Carnegie Mellon University (CMU). The papers imply that the disk drive module (DDM) manufacturers have perhaps misrepresented their reliability estimates, and asks major vendors to respond. So far, NetAppand EMC have responded.
I will not bother to re-iterate or repeat what others have said already, but make just a few points. Robin, you are free to consider this "my" official response if you like to post it on your blog, or point to mine, whatever is easier for you. Given that IBM no longer manufacturers the DDMs we use inside our disk systems, there may not be any reason for a more formal response.
Coke and Pepsi buy sugar, Nutrasweet and Splenda from the same sources
Somehow, this doesn't surprise anyone. Coke and Pepsi don't own their own sugar cane fields, and even their bottlers are separate companies. Their job is to assemble the components using super-secret recipes to make something that tastes good.
IBM, EMC and NetApp don't make DDMs that are mentioned in either academic study. Different IBM storage systems uses one or more of the following DDM suppliers:
Seagate (including Maxstor they acquired)
Hitachi Global Storage Technologies, HGST (former IBM division sold off to Hitachi)
In the past, corporations like IBM was very "vertically-integrated", making every component of every system delivered.IBM was the first to bring disk systems to market, and led the major enhancements that exist in nearly all disk drives manufactured today. Today, however, our value-add is to take standard components, and use our super-secret recipe to make something that provides unique value to the marketplace. Not surprisingly, EMC, HP, Sun and NetApp also don't make their own DDMs. Hitachi is perhaps the last major disk systems vendor that also has a DDM manufacturing division.
So, my point is that disk systems are the next layer up. Everyone knows that individual components fail. Unlike CPUs or Memory, disks actually have moving parts, so you would expect them to fail more often compared to just "chips".
If you don't feel the MTBF or AFR estimates posted by these suppliers are valid, go after them, not the disk systems vendors that use their supplies. While IBM does qualify DDM suppliers for each purpose, we are basically purchasing them from the same major vendors as all of our competitors. I suspect you won't get much more than the responses you posted from Seagate and HGST.
American car owners replace their cars every 59 months
According to a frequently cited auto market research firm, the average time before the original owner transfers their vehicle -- purchased or leased -- is currently 59 months.Both studies mention that customers have a different "definition" of failure than manufacturers, and often replace the drives before they are completely kaput. The same is true for cars. Americans give various reasons why they trade in their less-than-five-year cars for newer models. Disk technologies advance at a faster pace, so it makes sense to change drives for other business reasons, for speed and capacity improvements, lower power consumption, and so on.
The CMU study indicated that 43 percent of drives were replaced before they were completely dead.So, if General Motors estimated their cars lasted 9 years, and Toyota estimated 11 years, people still replace them sooner, for other reasons.
At IBM, we remind people that "data outlives the media". True for disk, and true for tape. Neither is "permanent storage", but rather a temporary resting point until the data is transferred to the next media. For this reason, IBM is focused on solutions and disk systems that plan for this inevitable migration process. IBM System Storage SAN Volume Controller is able to move active data from one disk system to another; IBM Tivoli Storage Manager is able to move backup copies from one tape to another; and IBM System Storage DR550 is able to move archive copies from disk and tape to newer disk and tape.
If you had only one car, then having that one and only vehicle die could be quite disrupting. However, companies that have fleet cars, like Hertz Car Rentals, don't wait for their cars to completely stop running either, they replace them well before that happens. For a large company with a large fleet of cars, regularly scheduled replacement is just part of doing business.
This brings us to the subject of RAID. No question that RAID 5 provides better reliability than having just a bunch of disks (JBOD). Certainly, three copies of data across separate disks, a variation of RAID 1, will provide even more protection, but for a price.
Robin mentions the "Auto-correlation" effect. Disk failures bunch up, so one recent failure might mean another DDM, somewhere in the environment, will probably fail soon also. For it to make a difference, it would (a) have to be a DDM in the same RAID 5 rank, and (b) have to occur during the time the first drive is being rebuilt to a spare volume.
The human body replaces skin cells every day
So there are individual DDMs, manufactured by the suppliers above; disk systems, manufactured by IBM and others, and then your entire IT infrastructure. Beyond the disk system, you probably have redundant fabrics, clustered servers and multiple data paths, because eventually hardware fails.
People might realize that the human body replaces skin cells every day. Other cells are replaced frequently, within seven days, and others less frequently, taking a year or so to be replaced. I'm over 40 years old, but most of my cells are less than 9 years old. This is possible because information, data in the form of DNA, is moved from old cells to new cells, keeping the infrastructure (my body) alive.
Our clients should approach this in a more holistic view. You will replace disks in less than 3-5 years. While tape cartridges can retain their data for 20 years, most people change their tape drives every 7-9 years, and so tape data needs to be moved from old to new cartridges. Focus on your information, not individual DDMs.
What does this mean for DDM failures. When it happens, the disk system re-routes requests to a spare disk, rebuilding the data from RAID 5 parity, giving storage admins time to replace the failed unit. During the few hours this process takes place, you are either taking a backup, or crossing your fingers.Note: for RAID5 the time to rebuild is proportional to the number of disks in the rank, so smaller ranks can be rebuilt faster than larger ranks. To make matters worse, the slower RPM speeds and higher capacities of ATA disks means that the rebuild process could take longer than smaller capacity, higher speed FC/SCSI disk.
According to the Google study, a large portion of the DDM replacements had no SMART errors to warn that it was going to happen. To protect your infrastructure, you need to make sure you have current backups of all your data. IBM TotalStorage Productivity Center can help identify all the data that is "at risk", those files that have no backup, no copy, and no current backup since the file was most recently changed. A well-run shop keeps their "at risk" files below 3 percent.
So, where does that leave us?
ATA drives are probably as reliable as FC/SCSI disk. Customers should chose which to use based on performance and workload characteristics. FC/SCSI drives are more expensive because they are designed to run at faster speeds, required by some enterprises for some workloads. IBM offers both, and has tools to help estimate which products are the best match to your requirements.
RAID 5 is just one of the many choices of trade-offs between cost and protection of data. For some data, JBOD might be enough. For other data that is more mission critical, you might choose keeping two or three copies. Data protection is more than just using RAID, you need to also consider point-in-time copies, synchronous or asynchronous disk mirroring, continuous data protection (CDP), and backup to tape media. IBM can help show you how.
Disk systems, and IT environments in general, are higher-level concepts to transcend the failures of individual components. DDM components will fail. Cache memory will fail. CPUs will fail. Choose a disk systems vendor that combines technologies in unique and innovative ways that take these possibilities into account, designed for no single point of failure, and no single point of repair.
So, Robin, from IBM's perspective, our hands are clean. Thank you for bringing this to our attention and for giving me the opportunity to highlight IBM's superiority at the systems level.
"With Cisco Systems, EMC, and VMware teaming up to sell integrated IT stacks, Oracle buying Sun Microsystems to create its own integrated stacks, and IBM having sold integrated legacy system stacks and rolling in profits from them for decades, it was only a matter of time before other big IT players paired off."
Once again we are reminded that IBM, as an IT "supermarket", is able to deliver integrated software/server/storage solutions, and our competitors are scrambling to form their own alliances to be "more like IBM." This week, IBM announced new ordering options for storage software with System x servers, including BladeCenter blade servers and IntelliStation workstations. Here's a quick recap:
IBM Tivoli Storage Manager FastBack v6.1 supports both Windows and Linux! FastBack is a data protection solution for ROBO (Remote Office, Branch Office) locations. It can protect Microsoft Exchange, Lotus Domino, DB2, Oracle applications. FastBack can provide full volume-level recovery, as well as individual file recovery, and in some cases Bare Machine Recovery. FastBack v6.1 can be run stand-alone, or integrated with a full IBM Tivoli Storage Manager (TSM) unified recovery management solution.
FlashCopy Manager v2.1
FlashCopy Manager uses point-in-time copy capabilities, such as SnapShot or FlashCopy, to protect application data using an application-aware approach for Microsoft Exchange, Microsoft SQL server, DB2, Oracle, and SAP. It can be used with IBM SAN Volume Controller (SVC), DS8000 series, DS5000 series, DS4000 series, DS3000 series, and XIV storage systems. When applicable, FlashCopy manager coordinates its work with Microsoft's Volume Shadow Copy Services (VSS) interface. FlashCopy Manager can provide data protection using just point-in-time disk-resident copies, or can be integrated with a full IBM Tivoli Storage Manager (TSM) unified recovery management solution to move backup images to external storage pools, such as low-cost, energy-efficient tape cartridges.
General Parallel File System (GPFS) v3.3 Multiplatform
GPFS can support AIX, Linux, and Windows! Version 3.3 adds support for Windows 2008 Server on 64-bit chipset architectures from AMD and Intel. Now you can have a common GPFS cluster with AIX, Linux and Windows servers all sharing and accessing the same files. A GPFS cluster can have up to 256 file systems. Each of these file systems can be up to 1 billion files, up to 1PB of data, and can have up to 256 snapshots. GPFS can be used stand-alone, or integrated with a full IBM Tivoli Storage Manager (TSM) unified recovery management solution with parallel backup streams.
For full details on these new ordering options, see the IBM [Press Release].
Well, it's Tuesday, and so it is "announcement day" again! Actually, for me it is Wednesday morning herein Mumbai, India, but since I was "press embargoed" until 4pm EDT in talking about these enhancements, I had to wait until Wednesday morning here to talk about them.
World's Fastest 1TB tape drive
IBM announced its new enterprise [TS1130 tape drive]and corresponding [TS3500 tape library support]. This one has a funny back-story. Last week while we were preparing the Press Release, we debated on whether we should compare the 1TB per cartridge capacity as double that of Sun's Enterprise T10000 (500GB), or LTO-4 (800GB). The problem changed when Sun announced on Monday they too had a 1TB tape drive, so now instead ofsaying that we had the "World's First 1TB tape drive", we quickly changed this to the "World's Fastest 1TB tape drive" instead. At 160MB/sec top speed, IBM's TS1130 is 33 percent faster than Sun's latest announcement. Sun was rather vague when they will actually ship their new units, so IBM may still end up being first to deliver as well.
While EMC and other disk-only vendors have stopped claiming that "tape is dead", these recent announcements from IBM and Sun indicate that indeed tape is alive and well. IBM is able to borrow technologies from disk, such as the Giant Magneto Resistive (GMR) head over to its tape offerings, which means much of the R&D for disk applies to tape, keeping both forms ofstorage well invested. Tape continues to be the "greenest" storage option, more energy efficient than disk, optical, film, microfiche and even paper.
On the LTO front, IBM enhanced the reporting capabilities of its[TS3310] midrange tape library. This includes identifying the resource utilization of the drives, reporting on media integrity, and improved diagnostics to support library-managed encryption.
IBM System Storage DR550
As a blended disk-and-tape solution, the [IBM System Storage DR550] easily replaces the EMC Centera to meet compliance storagerequirements. IBM announced that we have greatly expanded its scalability, being able to support both 1TBdisk drives, as well as being able to attach to either IBM or Sun's 1TB tape drives.
Massive Array of Idle Disks (MAID)
IBM now offers a "Sleep Mode" in the firmware of the [IBM System Storage DCS9550], which is often called "Massive Array of Idle Disks" (MAID) or spin-down capability. This can reduce the amount of power consumed during idle times.
That's a lot of exciting stuff. I'm off to breakfast now.
For the past three decades, IBM has offered security solutions to protect against unauthorized access. Let's take a look at three different approaches available today for the encryption of data.
Approach 1: Server-based
Server-based encryption has been around for a while. This can be implemented in the operating system itself, such as z/OS on the System z mainframe platform, or with an applicaiton, such as IBM Tivoli Storage Manager for backup and archive.
While this has the advantage that you can selectively encrypt individual files, data sets, or columns in databases, it has several drawbacks. First, you consume server resources to perform the encryption. Secondly, as I mention in the video above, if you only encrypt selected data, the data you forget to, or choose not to, encrypt may result in data exposure. Third, you have to manage your encryption keys on a server-by-server basis. Fourth, you need encryption capability in the operating system or application. And fifth, encrypting the data first will undermine any storage or network compression capability down-line.
Approach 2: Network-based
Network-based solutions perform the encryption between the server and the storage device. Last year, when I was in Auckland, New Zealand, I covered the IBM SAN32B-E4 switch in my presentation [Understanding IBM's Storage Encryption Options]. This switch receives data from the server, encrypts it, and sends it on down to the storage device.
This has several advantages over the server-based approach. First, we offload the server resources to the switch. Second, you can encrypt all the files on the volume. You can select which volumes get encrypted, so there is still the risk that you encrypt only some volumes, and not others, and accidently expose your data. Third, the SAN32B-E4 can centralized the encryption key management to the IBM Tivoli Key Lifecycle Manager (TKLM). This is also operating system and application agnostic. However, network-based encryption has the same problem of undermining any storage device compression capability, and often has a limit on the amount of data bandwidth it can process. The SAN32B-E4 can handle 48 GB/sec, with a turbo-mode option to double this to 96 GB/sec.
Approach 3: Device-based
Device-based solutions perform the encryption at the storage device itself. Back in 2006, IBM was the first to introduce this method on its [TS1120 tape drive]. Later, it was offered on Linear Tape Open (LTO-4) drives. IBM was also first to introduce Full Disk Encryption (FDE) on its IBM System Storage DS8000. See my blog post [1Q09 Disk Announcements] for details.
As with the network-based approach, the device-based method offloads server resources, allows you to encrypt all the files on each volume, can centrally manage all of your keys with TKLM, and is agnostic to operating system and application used. The device can compress the data first, then encrypt, resulting in fewer tape cartridges or less disk capacity consumed. IBM's device-based approach scales nicely. IBM has an encryption chip is placed in each tape drive or disk drive. No matter how many drives you have, you will have all the encryption horsepower you need to scale up.
Not all device-based solutions use an encryption chip per drive. Some of our competitors encrypt in the controller instead, which operates much like the network-based approach. As more and more disk drives are added to your storage system, the controller may get overwhelmed to perform the encryption.
The need for security grows every year. Enterprise Systems are Security-ready to protect your most mission critical application data.
Well, it's Tuesday again, and that means more announcements from IBM!
In conjunction with IBM's new [System z10 Business Class (BC)] mainframe designed for Small and Medium-sized Businesses (SMB), IBM also announced related storage productenhancements.
Yes, it's alive! Contrary to the FUD you might have read from our competitors, IBM continues to sell thousands and thousands of IBM System Storage DS6800 disk systems, and now enhances them with the optionfor 450GB 15K RPM drives. What is nice about these 450GB drives is that they are as fast or faster* than 300GBdrives, so the typical trade-off between performance and capacity do not apply.
(* I compared Seagate 15.6K (450GB) with 15.5K (300GB) models.
Avg Seek time (Read)
Avg Seek time (Write)
Full Seek time (Read)
Full Seek time (Write)
This may or may not result in application performance improvements, depending on workload pattern. Your mileage may vary.)
Our clients report back that these are incredibly stable systems that they don't have toworry about. This enhancement applies to both the [511/EX1 models] and [522/EX2 models].
Understanding that clients want complete solutions from single vendors, IBM offers synergy between System z and the IBM System Storage DS8000 disk systems. The latest R4.1 microcode upgrade offers two key features onthe various models [2107,
zHPF - High Performance FICON for System z. IBM was able to increase the throughput on 4 Gbps links. For OLTP workloads randomly accessing 4KB blocks, IBM internal tests showed zHPF doubled performance from 13,000 IOPSto 26,000 IOPS per channel. For sequential workloads, such as batch processing, zHPF increased performance 50 percent, from 350 MB/sec to 525 MB/sec.
In February, IBM previewed[IncrementalResync] for z/OS Metro Global Mirror. However, some concepts are better explained with pictures.
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 also have site "A" sending data over to site "C" asynchronously using z/OS Global Mirror. This is called "z/OS Metro Global Mirror".
In the past, if the disk system in site A failed, you would switch over to site B, which would have to resend send all the data again to site C to be resynchronized. This is because site B was not tracking what the System Data Mover (SDM) reader had or had not yet processed.
With DS8000 4.1, the "incremental resync" function that, along with using IBM HyperSwap, requires site B to only send and resync the data that was in-flight when the outage occurred. When you compare the difference in sending this limited amount of in-flight data with the traditional complete volume of data, you can see how "Incremental Resync" can resynchronize the data 95% faster, and also greatly decrease your bandwidth requirements. This reduces the risk in case a subsequent outage occurs.
Introduced originally in 1997 as the IBM Virtual Tape Server (VTS), the [IBMSystem Storage TS7700] series supports Grid capabilityto replicate tape image data across locations. Here's a quick recap of today's announcement:
Existing TS7740 can be upgraded up to 9TB of disk cache. New models can have up to 13TB of disk cache.
A new "tape-less" TS7720 that has up to 70TB of disk cache.
Integrate Library Management support. I discussed[IntegratedRemovable Media Manager (IRMM)] before, and this is basically IRMM inside. For those with TS3500 tape libraries,this support eliminates the need for a separate IBM 3953 L05 Library Manager.
TS1130 back-end tape drive support. These are the fastest 1TB drives in the industry, with support of built-in encryption, and now can be used asthe physical tape back-end for the virtual tape TS7740 repository.
While our competitors might be boarding up their windows in preparation for the economic downturn in the USAeconomy, IBM remains generating solid results. San Jose Mercury News has an article that discusses this titled[IBM's 3Q profit strong on global sales].There has never been a better time to buy from, or invest in, IBM!
There is still time to enroll for [IBM Edge], a conference focused on storage, to be held June 4-8 in Orlando, Florida. There is an early-bird discount until May 6!
I will be there all week! Here are the seven sessions I will be presenting at the Technical Edge side of the event:
Understanding Your Options for Storing Archive Data to Meet Compliance Challenges
This session will cover the IBM software and hardware solutions that your organization can use to store archive data, including features like immutability, Write-Once-Read-Many (WORM) technology and Non-Erasable, Non-Rewriteable (NENR) enforcement. The discussion will include high-level concepts like chronological and event-based retention, litigation hold and release, as well as an overview of the products and solutions from IBM that you can deploy today.
IBM Watson: How it Works and What it Means for Society Beyond Winning Jeopardy!
In 2011, the IBM Watson computer was able to beat the top-earning human winners on the trivia game-show “Jeopardy!” As I was the author of [How to Build Your Own Watson Junior in Your Basement], I have been asked to explain how the IBM Watson system was put together, how it works, and what examples of text mining and big data analytics means for society as we apply technology to meet tomorrow's challenges.
Using Social Media for IBM System Storage - Birds of a Feather
I will be moderating this Birds of a Feather, or BOF, session that will bring together a Q&A panel of experts on how social media can be leveraged to help you do your job, get the information you need to solve problems, and share your knowledge with others.
Data Footprint Reduction: Understanding IBM Storage Efficiency Options
Data Footprint Reduction is the catch-all term for a variety of technologies designed to help reduce storage costs. In this session, I will cover thin provisioning, space-efficient copies, deduplication and compression technologies, and describe the IBM storage products that provide these capabilities.
IBM's Storage Strategy in the Smarter Computing Era
Confused about IBM's new initiatives for Big Data analytics, Workload Optimized Systems, and Cloud Computing? This session will explain it all, and how IBM's strategy for its various storage products and solutions fit into these overall themes.
IBM SONAS and the IBM Cloud Storage Taxonomy
Confused over the different types of cloud storage? IBM's scale-out Network Attached Storage (SONAS) can be used in a variety of use cases. This session will provide an overview of IBM's SONAS solution, provide an update on the latest features and functions recently announced, and explain how it can be deployed in various private, public and hybrid cloud environments.
IBM Tivoli Storage Productivity Center Overview and Update
IBM has enhanced its premier storage infrastructure management tool: IBM Tivoli Storage Productivity Center. This session will provide both an overview of the product, and explain the latest features and functions recently announced.
Continuing my coverage of the 30th annual [Data Center Conference]. Here is a recap of some of the Tuesday afternoon sessions:
Brocade: Maximizing Your Cloud: How Data Centers Must Evolve
This was a session sponsored by Brocade to promote their concept of the "Ethernet Fabric". The first speaker, John McHugh, was from Brocade, and the second speaker was a client testimonial, Jamie Shepard, EVP for International Computerware, Inc.
John had an interesting take on today's network challenges. He feels that most LANs are organized for "North-South" traffic, referring to upload/downloads between clients and servers. However, the networks of tomorrow will need to focus on "East-West" traffic, referring to servers talking to other servers.
John was also opposed to integrated stacks that combine servers, storage and networking into a single appliance, as this prevents independent scaling of resources.
The Future of Backup is Not Backup
Primary data is growing at 40 to 60 percent compound annual growth rate (CAGR), but backup data is growing faster. Why? Because data that was not backed up before are now being backed up, including test data, development data, and mobile application data.
Backup costs are 19x more expensive than production software costs. There is an enormous gap in data protection because companies fail to factor this into their budgets. It is not uncommon for IT departments to use multiple backup tools, for example one tool for VMs, and another tool for servers, and a third product for desktops.
part of the problem is identifying who "buys" the backup software. The server team might focus on the operating systems supported. The storage team focuses on the disk and tape media supported. The application owners focus on the features and capabilities for backup that minimize impact to their application.
The analyst organized these issues into three "C's" of backup concerns: Cost, Capability and Complexity. Cost is not just the software license fee for the backup software, but the cost of backup media, courier fees, and transmisison bandwidth. Capability refers to the features and functions, and IT folks are tired of having to augment their backup solution with additional tools and scripts to compensate for lack of capability. Complexity refers to the challenges trying to get existing backup software to tackle new sources like Virtual Machines, Mobile apps, and so on.
Has everyone moved to a tape-less backup system? Polling results found that people are shifting back to tape, either in a tape-only environment, or to supplement their disk or disk-based virtual tape library (VTL). Here are the polling results:
The poll also showed the top three backup software vendors were Symantec, IBM and Commvault, which is consistent with marketshare. However, the analyst feels that by 2014, an estimated 30 percent of companies will change their backup softwar vendor out of frustration over cost, capability and/or complexity.
There are a lot new backup software products specific to dealing with Virtual Machines. Some are focused exclusively on VMware. When asked what tool people used to backup their VMs, the polling results showed the following. NOte that 20 percent for Other includes products from major vendors, like IBM Tivoli Storage Manager for Virtual Environments, as the analyst was more interested in the uptake of backup software from startups.
Some companies are considering Cloud Computing for backup. This is one area where having the cloud service provider at a distance is an actual advantage for added protection. A poll asking whether some or most data is backed up to the Cloud, either already today, or plans for the near future within the next 12 or 24 months, showed the following:
In addition to backup service providers, there are now several startups that offer file sharing, and some are adding "versioning" to this that can serve as an alternative to backup. These include DropBox, SugarSync, iCloud, SpiderOak and ShareFile.
The final topic was Snapshot and Disk Replication. These tend to be hardware-based, so they may not have options for versioning, scheduling, or application-aware capabilities normally associated with backup software. Space-efficient snapshots, which point unchanged data back to the original source, may not provide full data protection that disparate backup copies would provide. Here were polling results on whether snapshot/replication was used to augment or replace some or most of their backups:
Some of his observations and recommendations:
Maintenance is more expensive than acquisition cost. Don't focus on the tip of the iceberg. Some backup software is more efficient for bandwidth and media which will save tons of money in the long run.
Try to optimize what you have. He calls this the "Starbuck's effect". If you just need one coffee, then paying $4.50 for a cup makes sense. But if you need 100 coffees, you might be better off buying the beans.
Design backups to meet service level agreements (SLAs). In the past, backup was treated as one-size-fits-all, but today you can now focus on a workload by workload basis.
Be conservative in adopting new technologies until you have your backup procedures in place to handle data protection.
Backup is for operational recovery, not long-term retention of data. A poll showed two-thirds of the audience kept backup versions for longer than 60 days! Re-evaluate how long you keep backups, and how many versions you keep. If you need long-term retention, use archive process instead.
Recovery testing is a dying art. Practice recovery procedures so that you can do it safely and correctly when it matters most.
The analyst had a series of awesome pictures of large structures, the pyramids of Giza, the Chrysler building, and so on, and how they would look without their foundations in place. Backup is a foundation and should be treated as such in all IT planning purposes.
IT is evolving, but some basic needs like networking and backup procedures don't change. As companies re-evaluate their IT operations for Big Data, Cloud Computing and other new technologies, it is best to remember that some basic needs must be met as part of those evaluations.
The marketshare data for external disk systems has been released by IDC for 4Q09. Overall, the market dropped 0.7 percent, comparing 4Q09 versus 4Q08. While EMC was quick to remind everyone that they were able to [maintain their #1 position] in the storage subset of "external disk systems", with the same 23.7 percent marketshare they had back in 4Q08 and revenues that were essentially flat, the real story concerns the shifts in the marketplace for the other major players. IBM grew revenue 9 percent, putting it nearly 5 points of marketshare ahead of HP. HP revenues dropped 7 percent, moving it further behind. Not mentioned in the [IBM Press Release] were NetApp and Dell, neck and neck for fourth place, with NetApp gaining 16.8 percent in revenues, while Dell dropped 13.5 percent. Both NetApp and Dell now have about 8 percent marketshare each. These top five storage vendors represent nearly 70 percent of the marketshare.
Given that HP is IBM's number one competitor, not just in storage but all things IT, this was a major win. Bob Evans from InformationWeek interviews my fifth-line manager, IBM executive Rod Adkins [IBM Claims Hardware Supremacy] where he shares his views and opinions about HP, Oracle-Sun, Cisco and Dell.
I'll add my two cents on what's going on:
Shift in Servers causes Shift in Storage
Hundreds of customers are moving away from HP and Sun over to IBM servers, and with it, are chosing IBM's storage offerings as well. IBM's rock-solid strategy (which I outlined in my post [Foundations and Flavorings]) has helped explain the different products and how they are positioned. HP's use of Itanium processors, and Sun's aging SPARC line, are both reasons enough to switch to IBM's lastest POWER7 processors, running AIX, IBM i (formerly i5/OS) and Linux operating systems.
Thunder in the Clouds
Some analysts predict that by 2013, one out of five companies won't even have their own IT assets. IBM supports all flavors of private, public and hybrid cloud computing models. IBM has its own strong set of offerings, is also the number one reseller of VMware, and has cloud partnerships with both Google and Amazon. HP and Microsoft have recently formed an alliance, but they have different takes on cloud computing. HP wants to be the "infrastructure" company, but Microsoft wants to focus on its ["three screens and a public cloud"] strategy. Microsoft has decided not to make its Azure Cloud operating system available for private cloud deployments. By contrast, IBM can start you with a private cloud, then help you transition to a hybrid cloud, and finally to a public cloud.
In the latest eX5 announcement, IBM's x86-based servers can run 78 percent more virtual machines per VMware license dollar. This will give IBM an advantage as HP shifts from Itanium to an all x86-based server line.
Network Attached Storage
There seems to be a shift away from FC and iSCSI towards NAS and FCoE storage networking protocols. This bodes bad for HP's acquisition of LeftHand, and Dell's acquisition of EqualLogic. IBM's SONAS for large deployments, and N series for smaller deployments, will compete nicely against HP's StorageWorks X9000 system.
Storage on Paper no longer Eco-friendly
HP beats IBM when you include consumer products like printers, which some might consider "Storage on Paper". At IBM, we often joke that 96 percent of HP's profits come from over-priced ink cartridges. With the latest focus on the environment, people are printing less. I have been printing less myself, setting my default printer to generate a PDF file instead. There are several tools available for this, including [CutePDF] and [BullZip]. As IBM employees switch from Microsoft Office to IBM's [Lotus Symphony], it has built-in "export-to-PDF" capability as well. People are also going to their local OfficeMax or CartridgeWorld to get their cartridges refilled, rather than purchase new ones. That has to be hurting HP's bottom line.
Don't Forget About Storage Management
The leading storage management suites today are IBM's Tivoli Storage Productivity Center and EMC's Control Center. HP's Storage Essentials doesn't quite beat either of these, and management software is growing in importance to more and more customers.
He feels I was unfair to accuse EMC of "proprietary interfaces" without spelling out what I was referring to. Here arejust two, along with the whines we hear from customers that relate to them.
EMC Powerpath multipathing driver
Typical whine: "I just paid a gazillion dollars to renew my annual EMC Powerpath license, so you will have to come back in 12 months with your SVC proposal. I just can't see explaining to my boss that an SVC eliminates the need for EMC Powerpath, throwing away all the good money we just spent on it, or to explain that EMC chooses not to support SVC as one of Powerpath's many supported devices."
EMC SRDF command line interface
Typical whine: "My storage admins have written tons of scripts that all invoke EMC SRDF command line interfacesto manage my disk mirroring environment, and I would hate for them to re-write this to use IBM's (also proprietary) command line interfaces instead."
Certainly BarryB is correct that IBM still has a few remaining "proprietary" items of its own. IBM has been in business over 80 years, but it was only the last 10-15 years that IBM made a strategic shift away from proprietary and over to open standards and interfaces. The transformation to "openness" is not yet complete, but we have made great progress. Take these examples:
The System z mainframe - IBM had opened the interfaces so that both Amdahl and Fujitsu made compatible machines.Unlike Apple which forbids cloning of this nature, IBM is now the single source for mainframes because the other twocompetitors could not keep up with IBM's progress and advancements in technology.
Update: Due to legal reasons, the statements referring to Hercules and other S/390 emulators havebeen removed.
The z/OS operating system - While it is possible to run Linux on the mainframe, most people associate the z/OSoperating system with the mainframe. This was opened up with UNIX System Services to satisfy requests from variousgovernments. It is now a full-fledged UNIX operating system, recognized by the [Open Group] that certifies it as such.
As BarryB alludes, the unique interfaces for disk attachment to System z known as Count-Key-Data (CKD) was published so that both EMC and HDS can offer disk systems to compete with IBM's high-end disk offerings. Linux on System zsupports standard Fibre Channel, allowing you to attach an IBM SVC and anyone's storage. Both z/OS and Linux on System z support NAS storage, so IBM N series, NetApp, even EMC Celerra could be used in that case.
The System i itself is still proprietary, but recently IBM announced that it will now support standard block size (512 bytes) instead of the awkward 528 byte blocks that only IBM and EMC support today. That means that any storage vendor will be ableto sell disk to the System i environment.
Advanced copy services, like FlashCopy and Metro Mirror, are as proprietary as the similar offerings from EMCand HDS, with the exception that IBM has licensed them to both EMC and HDS. Thanks to cross-licensing, you can do [FlashCopy on EMC] equipment. Getting all the storage vendors to agree to open standards for these copy services is still workin progress under [SNIA], but at least people who have coded z/OS JCL batchjobs that invoke FlashCopy utilities can work the same between IBM and EMC equipment.
So for those out there who thought that my comment about EMC's proprietary interfaces in any way implied thatIBM did not have any of its own, the proverbial ["pot calling the kettle black"] so to speak, I apologize.
BarryB shows off his [PhotoShop skills] with the graphic below. I take it as a compliment to be compared to anAll-American icon of business success.
TonyP and Monopoly's Mr. Pennybags Separated at Birth?
However, BarryB meant it as a reference back to long time ago when IBMwas a monopoly of the IT industry, which according to [IBM's History], ended in 1973. In other words, IBMstopped being a monopoly before EMC ever existed as a company, and long before I started working for IBM myself.
The anti-trust lawsuit that BarryB mentions happened in 1969, which forced IBM to separate some of the software from its hardware offerings, and prevented IBM from making various acquisitions for years to follow, forcing IBM instead into technology partnerships. I'm glad that's all behind us now!
The Tucson Executive Briefing Center hosted 20 dignitaries from local companies and academia.
This is a historic competition, an exhibition match pitting a computer against the top two celebrated Jeopardy champions:
Brad Rutter, won $3.2 million USD on Jeopardy!, winning 5 days on the show, and then three later tournamets.
Ken Jennings, winning $2.5 million in a 74-day winning streak on Jeopardy!
One of the members of the audience had never seen an episode of Jeopardy! in his life.
(Note: there are NO SPOILERS in this blog post. If you have not yet watched the show, you are safe to continue reading the rest of this post. I will not
disclose the correct responses to any of the clues nor how well each contestant scored.)
Calline Sanchez, IBM Director, Systems Storage Development for Data Protection and Retention, kicked off today's ceremonies.
The IBM Watson computer, named after IBM founder Thomas J. Watson, has been developed over the past 4 years by a team of IBM scientists who set out to accomplish a grand challenge - build a computing system that rivals a human's ability to answer questions posed in natural language with speed, accuracy and confidence. IBM Research labs in the United States, Japan, China and Israel [collaborated with Artificial Intelligence (AI) experts at eight universities], including Massachusetts Institute of Technology (MIT), University of Texas (UT) at Austin, University of Southern California (USC), Rensselaer Polytechnic Institute (RPI), University at Albany (UAlbany), University of Trento (Italy), University of Massachusetts Amherst, and Carnegie Mellon University.
(Disclaimer: I attended the University of Texas at Austin. My father attended Carnegie Mellon University.)
Last week, NOVA on PBS had a special episode on the making of IBM Watson, you can [watch it online] on their website. Delaney Turner, IBM Social Media Communications Manager for Business Analytics Software, has posted [his observations of Nova].
Since IBM Watson is the size of 10 refrigerators and weighs over 14,000 pounds, it was easier to design the Jeopardy! set at the TJ Watson Research lab in Yorktown Heights, NY, than to ship it over to California where the show is normally recorded. Two of the visual designers that worked on this set, as well as on the visual appearance of Watson, live in Tucson and were part of our audience today.
The IBM Challenge consists of a two-game tournament, where the scores of both games will be added to determine winner rankings. The producers of Jeopardy! will give $1 million dollars USD to first place, $300,000 to second place, and $200,000 to third place. Regardless of outcome, [IBM will donate all of its winings to charity]. The two human contestants plan to donate half of their earnings to their favorite charities as well.
Jeopardy! The IBM Challenge
Alex Trebek introduces IBM Watson, explaining that it can neither hear nor see. It will receive all information electronically. Categories and clues will be sent as text files via TCP/IP over Ethernet at the same time the two human contestants see them so that all have the same time to think about the right answer.
Watson has two rows of five racks, back to back. This was done so that cold air could rise up from holes in the tile floors around the unit, and all the hot air would be forced into the center and up to the ceiling return. This technique is known as "hot aisle/cold aisle" design. Alex Trebek opens one of the rack doors to show a series of 4U-high IBM Power 750 servers.
The avatar is a representation of Watson, as the machine itself is too big to fit behind the podium. The avatar is IBM's "Smarter Planet" logo with orbiting streaks and circles. It shows "Green" when it has high confidence, and orange when it gets an answer wrong. When busy thinking, the streaks and circles speed up, the closest we will see to "watching a computer sweat."
During the show, an "Answer panel" shows Watson's top three candidate responses, with confidence level compared to its current "buzz threshold".
Watson knows what it knows, and knows what it doesn't know. Here is an [Interactive Watson Game] on New York Times website to give you an idea of how the answer panel works. I was impressed with how close all three candidate answers were. In a question about Olympic swimmers, all three candidates are Olympic swimmers. In a question about the novel "Les Miserables", all three candidates were characters of that novel.
Well, IBM Watson did well, but missed answered some questions incorrectly. This [parody Slate video] pokes fun at this. Here were some discussions we had after the show ended:
IBM did not do well in categories that required [abductive reasoning]. For example, to identify two or three things that happened in different years, and then postulate that what they all have in common is a specific decade (such as the 1950s) is difficult.
Watson does not hear the wrong answers from the two human contestants. For one question, Ken buzzes in first, guesses wrong, then Watson buzzes in with the same exact response. Alex Trebek rebukes Watson with "No, Ken just said that!" Brad would learn from their mistakes and guess correctly for the score.
Watson is provided the correct answer after a contestant guesses it correctly, or if nobody does, when Alex provides the correct response. This is sent as a text message to Watson immediately, so that it can use this information to adjust its algorithms and machine-learning for future clues in that same category. This was evident in the "Answer panel" on the fourth and fifth attempts on the category of "Decades".
With this demonstration, IBM Research has advanced science by leaps and bounds for the Articial Intelligence community. IBM is a leader in Business Analytics, and this technology will find uses in a variety of industries. The average knowledge worker spends 30 percent of her time looking for information on corporate data repositories. By demonstrating a computer that can provide answers quickly, employees will be more productive, make stronger business decisions, and have greater insight.
Day 1 was only able to cover the first round of Game 1. This allowed more time to talk about the history and technology of IBM Watson. Tomorrow, the contestants will finish Game 1 and head into Game 2.
Well, I'm back from my adventure. For those who did not follow my tweets, here is a quick recap. Not counting the day we flew from Tucson to Minneapolis, or the day we flew from Memphis back to Tucson, Mo and I spent nine days on the road, covering 1549 miles, or roughly two thirds of the Mississippi River.
Celebrated Fourth of July at the [Wide River Winery] just north of Clinton, IA. Saw "The Last Airbender" at the local cinema.
Buffalo Bill Cody museum was closed on Monday, ate my first loose-meat sandwich lunch at Maid-Rite in Moline, IL, the button museum, aka [Muscatine History and Industry Center] was also closed on Monday, took pictures in the corn fields at Oquawka, IA, ate smoked Carp from [Quality Fisheries, in Niota, IA], ate raisin pie at the Maid-Rite in Quincey, IL. Stayed in a hotel in Hannibal, MO - home of Mark Twain.

Tour of [Graceland Mansion], home of Elvis Presley, and [Mud Island], ate dinner at Gus' World Famous Hot & Spicy Chicken, all in Memphis, TN.
Well, it's Tuesday, and that means IBM announcements! Today is bigger, as there are a lot of Dynamic Infrastructure announcements throughout the company with a common theme, cloud computing and smart business systems that support the new way of doing things. Today, IBM announced its new "IBM Smart Archive" strategy that integrates software, storage, servers and services into solutions that help meet the challenges of today and tomorrow. IBM has been spending the past few years working across its various divisions and acquisitions to ensure that our clients have complete end-to-end solutions.
IBM is introducing new "Smart Business Systems" that can be used on-premises for private-cloud configurations, as well as by cloud-computing companies to offer IT as a service.
IBM [Information Archive] is the first to be unveiled, a disk-only or blended disk-and-tape Information Infrastructure solution that offers a "unified storage" approach with amazing flexibility for dealing with various archive requirements:
For those with applications using the IBM Tivoli Storage Manager (TSM) or IBM System Storage Archive Manager (SSAM) API of the IBM System Storage DR550 data retention solution, the Information Archive will provide a direct migration, supporting this API for existing applications.
For those with IBM N series using SnapLock or the File System Gateway of the DR550, the Information Archive will support various NAS protocols, deployed in stages, including NFS, CIFS, HTTP and FTP access, with Non-Erasable, Non-Rewriteable (NENR) enforcement that are compatible with current IBM N series SnapLock usage.
For those using NAS devices with PACS applications to store X-rays and other medical images, the Information Archive will provide similar NAS protocol interfaces. Information Archive will support both read-only data such as X-rays, as well as read/write data such as Electronic Medical Records.
Information Archive is not just for compliance data that was previously sent to WORM optical media. Instead, it can handle all kinds of data, rewriteable data, read-only data, and data that needs to be locked down for tamper protection. It can handle structured databases, emails, videos and unstructured files, as well as objects stored through the SSAM API.
The Information Archive has all the server, storage and software integrated together into a single machine type/model number. It is based on IBM's General Parallel File System (GPFS) to provide incredible scalability, the same clustered file system used by many of the top 500 supercomputers. Initially, Information Archive will support up to 304TB raw capacity of disk and Petabytes of tape. You can read the [Spec Sheet] for other technical details.
For those who prefer a more "customized" approach, similar to IBM Scale-Out File Services (SoFS), IBM has [Smart Business Storage Cloud]. IBM Global Services can customize a solution that is best for you, using many of the same technologies. In fact, IBM Global Services announced a variety of new cloud-computing services to help enterprises determine the best approach.
In a related announcement, IBM announced [LotusLive iNotes], which you can think of as a "business-ready" version of Google's GoogleApps, Gmail and GoogleCalendar. IBM is focused on security and reliability but leaves out the advertising and data mining that people have been forced to tolerate from consumer-oriented Web 2.0-based solutions. IBM's clients that are already familiar with on-premises version of Lotus Notes will have no trouble using LotusLive iNotes.
There was actually a lot more announced today, which I will try to get to in later posts.
