Jim is an IBM Fellow for IBM Systems and Technology Group. There are only 73 IBM Fellows currently working for IBM, and this is the highest honor IBM can bestow on an employee. He has been working with IBM since 1968.
He is tasked with predicting the future of IT, and help drive strategic direction for IBM. Cost pressures, requirements for growth, accelerating innovation and changing business needs help influence this direction.
IBM's approach is to integrate four different "IT building blocks":
Scale-up Systems, like the IBM System Storage DS8000 and TS3500 Tape Library
Resource Pools, such as IBM Storage Pools formed from managed disks by IBM SAN Volume Controller (SVC)
Integrated stacks and appliances, integrated software and hardware stacks, from Storwize V7000 to full rack systems like IBM Smart Analytics Server or CloudBurst.
Mobility of workloads and resources requires unified end-to-end service management. Fortunately, IBM is the #1 leader in IT Service Management solutions.
Jim addressed three myths:
Myth 1: IT Infrastructures will be homogenous.
Jim feels that innovations are happening too rapidly for this to ever happen, and is not a desirable end-goal. Instead, a focus to find the right balance of the IT building blocks might be a better approach.
Myth 2: All of your problems can be solved by replacing everything with product X.
Jim feels that the days of "rip-and-replace" are fading away. As IBM Executive Steve Mills said, "It isn't about the next new thing, but how well new things integrate with established applications and processes."
Myth 3: All IT will move to the Cloud model.
Jim feels a substantial portion of IT will move to the Cloud, but not all of it. There will always be exceptions where the old traditional ways of doing things might be appropriate. Clouds are just one of the many building blocks to choose from.
Jim's focus lately has been finding new ways to take advantage of virtualization concepts. Server, storage and network virtualization are helping address these challenges through four key methods:
Sharing - virtualization that allows a single resource to be used by multiple users. For example, hypervisors allow several guest VM operating systems share common hardware on a single physical server.
Aggregation - virtualization that allows multiple resources to be managed as a single pool. For example, SAN Volume Controller can virtualize the storage of multiple disk arrays and create a single storage pool.
Emulation - virtualization that allows one set of resources to look and feel like a different set of resources. Some hypervisors can emulate different kinds of CPU processors, for example.
Insulation - virtualization that hides the complexity from the end-user application or other higher levels of infrastructure, making it easier to make changes of the underlying managed resources. For example, both SONAS and SAN Volume Controller allow disk capacity to be removed and replaced without disruption to the application.
In today's economy, IT transformation costs must be low enough to yield near-term benefits. The long-term benefits are real, but near-term benefits are needed for projects to get started.
What set's IBM ahead of the pack? Here was Jim's list:
100 Years of Innovation, including being the U.S. Patent leader for the last 18 years in a row
IBM's huge investment in IBM Research, with labs all over the globe
Leadership products in a broad portfolio
Workload-optimized designs with integration from middleware all the way down to underlying hardware
Comprehensive management software for IBM and non-IBM equipment
Clod is an IBM Distinguished Engineer and Chief Technical Strategist for IBM System Storage. His presentation focused on trends and directions in the IT storage industry. Clod started with five workload categories:
To address these unique workload categories, IBM will offer workload-optimized systems. The four drivers on the design for these are performance, efficiency, scalability, and integration. For example, to address performance, companies can adopt Solid-State Drives (SSD). Unfortunately, these are 20 times more expensive dollar-per-GB than spinning disk, and the complexity involved in deciding what data to place on SSD was daunting. IBM solved this with an elegant solution called IBM System Storage Easy Tier, which provides automated data tiering for IBM DS8000, SAN Volume Controller (SVC) and Storwize V7000.
For scalability, IBM has adopted Scale-Out architectures, as seen in the XIV, SVC, and SONAS. SONAS is based on the highly scalable IBM General Parallel File System (GPFS). File systems are like wine, they get better with age. GPFS was introduced 15 years ago, and is more mature than many of the other "scalable file systems" from our competition.
Areal Density advancements on Hard Disk Drives (HDD) are slowing down. During the 1990s, the IT industry enjoyed 60 to 100 percent annual improvement in areal density (bits per square inch). In the 2000s, this dropped to 25 to 40 percent, as engineers are starting to hit various physical limitations.
Storage Efficiency features like compression have been around for a while, but are being deployed in new ways. For example, IBM invented WAN compression needed for Mainframe HASP. WAN compression became industry standard. Then IBM introduced compression on tape, and now compression on tape is an industry standard. ProtecTIER and Information Archive are able to combine compression with data deduplication to store backups and archive copies. Lastly, IBM now offers compression on primary data, through the IBM Real-Time Compression appliance.
For the rest of this decade, IBM predicts that tape will continue to enjoy (at least) 10 times lower dollar-per-GB than the least expensive spinning disk. Disk and Tape share common technologies, so all of the R&D investment for these products apply to both types of storage media.
For integration, IBM is leading the effort to help companies converge their SAN and LAN networks. By 2015, Clod predicts that there will be more FCoE purchased than FCP. IBM is also driving integration between hypervisors and storage virtualization. For example, IBM already supports VMware API for Array Integration (VAAI) in various storage products, including XIV, SVC and Storwize V7000.
Lastly, Clod could not finish a presentation without mentioning Cloud Computing. Cloud storage is expected to grow 32 percent CAGR from year 2010 to 2015. Roughly 10 percent of all servers and storage will be in some type of cloud by 2015.
As is often the case, I am torn between getting short posts out in a timely manner versus spending some more time to improve the length and quality of information, but posted much later. I will spread out the blog posts in consumable amounts throughout the next week or two, to achieve this balance.
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.
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.
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.
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].
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.
"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.
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.
