Well, it's Tuesday again, and you know what that means! IBM announcements!
Today, I am in New York visiting clients. The weather is a lot nicer than I expected. Here is a picture of the Hudson River through some trees with leaves turning color. Something we don't see in Tucson! Our cactus and pine trees stay green year-round!
The announcements today center around the IBM PureSystems family of expert integrated systems. The PureFlex is based on Flex System components. The Flex System chassis is 10U high that hold 14 bays, consisting of 7 rows by 2 columns. Computer and Storage nodes fit in the front, and switches, fans and power supplies in the back. Here is a quick recap:
IBM Flex System Compute Nodes
The x220 Compute Node is a single-bay low-power 2-socket x86 server. The x440 Compute Node is a powerful double-bay (1 row, 2 columns). The p260 Compute Node is a single-bay server based on the latest POWER7+ CPU processor.
IBM Flex System Expansion Nodes
Do you remember those old movies where a motorcycle would have a sidecar that could hold another passenger, or extra cargo? IBM introduces "Expansion Nodes" for the x200 series single-bay Compute nodes. The idea here is that in a single column, you have one bay for the Compute node, and then on the side in the next bay (same column) you have an Expanions node. There are two choices:
Storage Expansion Node allows you to have eight additional drives
PCIe Expansion Node allows to to have four PCIe cards, which could include the SSD-based PCIe cards from IBM's recent acquisition, Texas Memory Systems.
There are times where one or two internal drives are just not enough storage for a single server, and these expanion nodes could just be the perfect solution for some use cases.
IBM Flex System V7000 Storage Node
I saved the best for last! The Flex System V7000 Storage Node is basically the IBM Storwize V7000 repackaged to fit into the Flex System chassis. This means that in the front of the chassis, the Flex System V7000 takes up four bays (2 rows by 2 columns). In the back of the chassis are the power supplies, fans and switches.
The new Flex System V7000 supports everything the Storwize V7000 does except the upgrade to "Unified" through file modules. For those who want to have Storwize V7000 Unified in their PureFlex systems, IBM will continue to offer the outside-the-chassis original Storwize V7000 that can have two file modules added for NFS, CIFS, HTTPS, FTP and SCP protocol support.
IBM Flex System Converged Network Switch
The Converged Network Switch provide Fibre Channel over Ethernet (FCoE) directly from the chassis. This eliminates the need for a separate "Top-of-Rack" switch, and allows the new Flex System V7000 Storage Node to externally virtualize FCoE-based disk arrays.
Patterns of Expertise for Infrastructure
The original patterns of expertise focused on the PureApplication Systems. Now IBM has added some for the Infrastructure on PureFlex systems.
IBM has sold over 1,000 Flex System and PureFlex systems, across 40 different countries around the world, since their introduction a few months ago in April! These latest enhancements will help solidify IBM's industry leadership,
Well, it's Tuesday again, and you know what that means! IBM Announcements!
Today also happens to be [Election Day] in the United States, and some have questioned IBM's logic of making major storage announcements on Election Day. During the campaigns, a major theme was to help Small and Medium size businesses, because these are the engines of economic growth and improved employment.
Hopefully, you all saw today's Launch Webcast on these announcements, but in case you missed it, waiting in line at the polling station to cast your vote, or caught without electricity or Internet access from [Superstorm Sandy], it is now available [On-Demand].
The 2U control enclosure can have up to four additional 2U expansion enclosures, for a maximum of 120 drives, or 180TB of raw disk capacity. Like the Storwize V7000, the Storwize V3700 supports a [large number of servers and operating systems.]

IBM LTO-6 drives and midrange tape libraries
Last month, IBM's [Tape and Storage Hypervisor Announcements] included LTO-6 for the enterprise-class TS3500 tape library. Today, the LTO-6 support is complete with support for midrange tape drives and libraries.
There are two tape drive models. The TS2260 is based on the half-height drive, intended for occasional 9-to-5 usage. The TS2360 is based on the full-height drive, intended for 24x7 access. These drives can read LTO-4 and LTO-5 tape cartridge media, and can write LTO-5 cartridge media. The new LTO-6 tape cartridge media is expected to be available next month.
In addition to the IBM TS3500 Enterprise Tape Library, LTO-6 is now supported on all of the midrange tape libraries: TS2900, TS3100, TS3200 and TS3310.
IBM Linear Tape File System Library Edition V2.1.2
There are two levels of [Linear Tape File System], or LTFS for short. The first is the Single Drive Edition (LTFS-SDE), which allows you to attach an LTO-5, LTO-6 or TS1140 tape drive to a single workstation, and allow you to mount tape cartridges as easy as mounting USB memory sticks. This presents a full file system view that allows you to read, edit, create, and even drag-and-drop files to other file systems. The LTFS-SDE driver is available for Windows, Linux, and Mac OS.
The second is the Library Edition (LTFS-LE), which allows you to mount the entire tape library as a file system. Each tape cartridge in the library is presented as a subdirectory folder, that you can access like any file system on disk. This was only available for Linux systems, which could then export the files through NFS, FTP or HTTP protocols to other clients. Now, with release v2.1.2, LTFS-LE supports Windows servers, so that you can share the files with other clients through CIFS as well.
A lot was announced yesterday, so I decided to break it up into several separate posts. This is part 2 in my 3-part series, focusing on: Storwize V7000 Unified, LTO-6 tape, and the SmartCloud Virtual Storage Center.
The Storwize V7000 Unified is a product that consists of a 2U-high Storwize V7000 control enclosure that provides block-based access, combined with two 2U-high File Modules that provide file-based NAS protocols: CIFS, NFS, HTTPS, SCP and FTP. The problem was that when it was introduced, it was based on Storwize V7000 v6.3, so when the Storwize V7000 v6.4 features were announced last June, they did not apply to the Storwize V7000 Unified.
That is all fixed now, so the Storwize V7000 Unified now supports the full v6.4 features, including Real-time Compression for both file and block-based access to primary data, and Fibre Channel over Ethernet (FCoE) for block access.
The two File Modules are no longer limited to a single Storwize V7000 control enclosure, you can now connect to up to four control enclosures clustered together. Combined with up to nine expansion enclosures for additional disk raises the total maximum to 960 drives.
If you don't already have an Active Directory or LDAP server, the Storwize V7000 Unified now offers an embedded LDAP server, for smaller deployments that want to reduce the number of servers they need to purchase for a complete solution.
Like the [IBM XIV Gen3 storage system], both the Storwize V7000 and V7000 Unified now also support the OpenStack Nova-volume interface.
Lastly, if you have a Storwize V7000 v6.4, you can upgrade it to a Storwize V7000 Unified by simply adding the two File Modules. This can be done in the field.
IBM LTO-6 for tape libraries and drives
IBM introduces the sixth generation of Linear Tape Open (LTO-6) drives, which can be used as stand-alone IBM TS1060 drives, or in IBM tape libraries. As with previous models of LTO, the LTO-6 can read two older generations (LTO-4 and LTO-5) tape media, and can write to previous generation (LTO-5) tape media. You can buy the LTO-6 drives now, and use the older media until LTO-6 tape cartridges are available (hopefully later this year!)
My friend, Brad Johns, from Brad Johns Consulting, has a great post on this [LTO-6 Announcement]. While you expect the new drives to be faster with a denser tape media format, the key advantage to the LTO-6 is that it improves the compression algorithm, from the previous 2:1 to the new 2.5:1 compression ratio:
Thus, with the improved compression, the LTO-6 is 40 percent faster, with double the tape cartridge density. This can reduce backup times by 30 percent, increase the amount of data that sits in your automated tape libraries, and reduce the courier costs sending tapes off-site.
IBM SmartCloud Virtual Storage Center v5.1
Last year, IBM coined the phrase "Storage Hypervisor" to refer to the underlying technology in the IBM SAN Volume Controller (SVC) and Storwize V7000 disk systems.
At the IBM Edge conference last June, my colleague Mike Griese presented [SmartCloud Virtual Storage Center]. Back then, it was a pilot program (beta test), and this week, IBM announces that it will be formally available as a product.
The idea was simple: take the basic storage hypervisor, and add the necessary software to make it a complete solution.
If all of your disk is currently virtualized behind IBM SAN Volume Controller (SVC), or you want to put all of your data behind SVC, then SmartCloud Virtual Storage Center is for you. Basically, for one per-TB price, you get all of the following:
The software features of SAN Volume Controller v6.4, including FlashCopy, Metro Mirror and Global Mirror.
The full advanced features of IBM Tivoli Storage Productivity Center v5.1, including the Storage Analytics Engine that does "Right-Tiering", recommending which LUNs should be moved entirely from one disk system to another, based on policies and access patterns.
IBM Tivoli Storage FlashCopy Manager v3.2 which manages FlashCopy with full coordination with applications, including Microsoft Exchange, SQL Server, DB2, Oracle, SAP, and VMware. This ensures that the FlashCopy destination copies are clean, eliminating the need to run backout or redo logs to correct any incomplete units of work.
If this combination sounds familiar, it was based on IBM's previous attempt called [Rapid Application Storage] which combined the Storwize V7000 with Tivoli Storage Productivity Center Midrange Edition and FlashCopy Manager.
The key difference is that SmartCloud VSC does not include the SVC hardware itself, you buy this separately. If you want Real-time Compression, that is charged separately for the subset of TB of the volumes that you select for compression.
Every year, I teach hundreds of sellers how to sell IBM storage products. I have been doing this since the late 1990s, and it is one task that has carried forward from one job to another as I transitioned through various roles from development, to marketing, to consulting.
This week, I am in the city of Taipei [Taipei] to teach Top Gun sales class, part of IBM's [Sales Training] curriculum. This is only my second time here on the island of Taiwan.
As you can see from this photo, Taipei is a large city with just row after row of buildings. The metropolitan area has about seven million people, and I saw lots of construction for more on my ride in from the airport.
The student body consists of IBM Business Partners and field sales reps eager to learn how to become better sellers. Typically, some of the students might have just been hired on, just finished IBM Sales School, a few might have transferred from selling other product lines, while others are established storage sellers looking for a refresher on the latest solutions and technologies.
I am part of the teach team comprised of seven instructors from different countries. Here is what the week entails for me:
Monday - I will present "Selling Scale-Out NAS Solutions" that covers the IBM SONAS appliance and gateway configurations, and be part of a panel discussion on Disk with several other experts.
Tuesday - I have two topics, "Selling Disk Virtualization Solutions" and "Selling Unified Storage Solutions", which cover the IBM SAN Volume Controller (SVC), Storwize V7000 and Storwize V7000 Unified products.
Wednesday - I will explain how to position and sell IBM products against the competition.
Thursday - I will present "Selling Infrastructure Management Solutions" and "Selling Unified Recovery Management Solutions", which focus on the IBM Tivoli Storage portfolio, including Tivoli Storage Productivity Center, Tivoli Storage Manager (TSM), and Tivoli Storage FlashCopy Manager (FCM). The day ends with the dreaded "Final Exam".
Friday - The students will present their "Team Value Workshop" presentations, and the class concludes with a formal graduation ceremony for the subset of students who pass. A few outstanding students will be honored with "Top Gun" status.
These are the solution areas I present most often as a consultant at the IBM Executive Briefing Center in Tucson, so I can provide real-life stories of different client situations to help illustrate my examples.
The weather here in Taipei calls for rain every day! I was able to take this photo on Sunday morning while it was still nice and clear, but later in the afternoon, we had quite the downpour. I am glad I brought my raincoat!
This week I am in Orlando, Florida for the IBM Edge conference. This is the last day, so it ends early for people who want to get home to their datacenters (er.. families) for the weekend.
How Real-Time Compression Can Maximize Storage Efficiency for Production Applications
This was a split session with two speakers. First, Ian Rimmer, Senior IT Engineer and Architect at iBurst, presented their experience with the IBM Real-Time Compression Appliance in front of NetApp NAS storage arrays. Second, Jerry Haigh, IBM offering manager for IBM System Storage, presented the new Real-Time compression feature announced this week on IBM SAN Volume Controller (SVC) and Storwize V7000.
iBurst is the #1 Wireless Telecom for South Africa. The also offer cable broadband and VOIP. They have 200 employees servicing 120,000 subscriber/households. They need to keep five years' worth of text files, and have chosen real-time compression of their NAS storage. This was before IBM acquired the Storwize company, as they have been using it for the past six years.
The monetary savings from compression was used to purchase Performance Accelerator Modules (PAM) cards for their NetApp NAS gear, which benefit from the compression (more data stored in SSD to improve performance).
For backup, they use NDMP with Symantec NetBackup that keeps data in its compressed form as it is written to tape. They have an IBM TS3100 library with LTO tape as the backup repository.
Jerry Haigh presented Real-Time compression for primary disk data. Unlike the competition, this is designed to be used with primary data, including databases, and does this real-time, not post-process. In some performance tests, DB2 compressed on 48 drives out-performed the same data uncompressed on 96 drives. In another test focused on VMware Vmark benchmark, the compressed data was able to be same or better performance as uncompressed. In a third test with SVC virtualizing XIV running Oracle ORION test, the Oracle databases compressed 50 to 64 percent, and had better performance.
For those who already have SVC or Storwize V7000, consider a 45-day trial to check out compression for yourself.
NAS File Systems: Access and Authentication
Mark Taylor, IBM Technical Specialist for SONAS, N series and Storwize V7000 Unified, presented the nuances of authentication and authorization for NAS file systems. The differences between these two are:
Authentication - Yes, you are who you are.
Authorization - Yes, you are permitted to do what you are trying to do
(Prior to working with SONAS, my only experience with access and authentication in NAS was setting up my LAN at home, which I have connecting my Mac, Linux and Windows machines. I have both N series and SONAS at the IBM Executive Briefing Center in Tucson, Arizona, so I know first-hand how complicated NAS access and authentication systems can be.
A few months ago, I taught "Intro to NAS" as one of my topics at the Top Gun class in Argentina and Brazil. Several of the students had mentioned they thought they knew NAS solutions but had not realized all the technical issues with access and authentication that I discussed in my presentation.)
Mark explained the differences between Windows NTFS-style System identifiers (SID), versus UNIX-style user and group identifiers (UID, GID). For NAS solutions that support both CIFS and NFS, there are four options:
Microsoft Active Director (AD) extended with Identity Management for UNIX, formerly known as Services for UNIX (SFU). AD servers normally store SID information, but the extensions add extra columns to hold UID/GID mappings.
AD with Network Information Service (NIS) server. The problem with this approach is that AD and NIS are separate databases, and you need to coordinate updates to them, and their backups.
Lightweight Directory Access Protocol (LDAP) with SAMBA extensions. LDAP holds UID/GID information, and the SAMBA extensions adds extra columns to hold SID mapping.
Local mapping. The dangerous part of local mapping is that the storage admin is also the security admin, and you may want different people doing these roles.
Of these four methods, Mark recommends the first and third as best practices for multi-protocol authentication.
SID-to-UID mapping, UID-to-SID mapping
SONAS and Storwize V7000
SID-to-UID/GID mapping, NFS v4 ACLs
NFS v4 ACLs
Mark then explained how NFS v4 ACLs work, basically an ordered collection of "Access Control Elements" or ACEs. Each ACE on the ACL may "allow" or "deny" the request. You want to avoid "Inheritance" as that can cause problems and unxpected results.
That's it folks. Next week, I am spending time with my research buddies at the Almaden Research Center near San Jose, California, and then it is off to Moscow, Russia to kick off a series of IBM events called "Edge Comes to You" (ECTY).
The ECTY conferences will be a smaller subset of the Edge conference here in Orlando, but offered in other countries for those who were unable to travel to the United States.
This week I am in Orlando, Florida for the IBM Edge conference. Thursday evening after all the other sessions, we had a Free-for-All, a Q&A panel across all storage topics, moderated by Scott Drummond. The conference officially ends at noon tomorrow, but for many, this is the last session, as people fly out Friday morning. Here are the questions and the panel responses during the session.
When will IBM unify their storage management between Mainframe z/OS and the distributed systems platforms?
IBM offers a Change and Configuration Management Data Base (CCMDB) for this purpose with appropriate collectors from z/OS and distributed systems, but hasn't sold well.
When will IBM devices have RESTful interfaces?
Both IBM Systems Director and IBM Tivoli Storage Productivity Center (TPC) offer RESTful APIs. IBM Systems Director can manage z/VM and Linux on System z, as well as Power Systems and x86 based distributed systems. Since October 2008, IBM's Project Zero introduced RESTful interfaces to PHP and Groovy software running on WebSphere sMash environments. We have not heard much about this since 2008.
Will IBM TPC support NPIV on Power Systems?
TPC 5.1 has toleration support for this, showing the first port connection discovered, but not all connections, and we expect to retrofit this toleration to TPC 4.2.2 Fixpack 2. Hopefully, we will have full support in a future release.
We would like TPC for Replication to run on Linux for System z. We do not run z/OS at the disaster recovery site location.
Submit an IBM Request for Enhancement [RFE] for this. We have TPC for Replication on z/OS, as well as the distributed systems version that runs on Windows, Linux and AIX.
We have enhancements we would like to see for XIV and SONAS also, can we use the RFE process for this also?
Yes, submit the requirements for our review.
We heard the Statement of Direction that there would be storage integrated into the PureSystems. What exactly does that mean?
The PureSystems family of expert-integrated systems is based on a new chassis that has a front part, a midplane, and a back-part. All IBM System Storage products that support x86 and Power Systems can work with PureSystems. However, IBM does not yet offer storage that fits in the front part of the PureFlex chassis, but the Statement of Direction indicates that we intend to offer that option. Until then, the IBM Storwize V7000 is the storage of choice that can be put into the PureSystems rack, but outside the individual chasses.
We see some features like Real-Time Compression being put into the SAN Volume Controller (SVC), and other features put into the back-end devices. How are we supposed to make sense of this?
IBM's new pilot program, the SmartCloud Virtual Storage Center, to bring these all together. In general, we have design teams of system architects that determine which features go in which products, and prioritize accordingly.
We heard the IBM Executives during the opening session indicate that IBM's strategy involves supporting Big Data, but I haven't seen any storage that supports native Hadoop interfaces. Did I miss something?
First, I want to emphasize that Big Data is more than just MapReduce workloads. IBM offers Streams and BigInsights software to handle text, as well as Business Intelligence and Data Warehouse solutions for structured data. IBM's General Parallel File System (GPFS) has a Shared-Nothing-Cluster (SNC) mode with Hadoop interfaces that runs twice as fast as Hadoop's native HDFS file system. The storage products we recommend for Big Data are the SONAS and the DCS3700 disk systems, as both are optimized for the sequential workloads Big Data represents.
Everytime we upgrade our SVC, we review the list for SDDPCM multi-pathing and see that we need to upgrade our back-end DS8000 microcode up to recommended levels. Can we get a list of combinations that work from other customers?
The advantage of storage hypervisors like SVC is that we can separate the multi-pathing driver from the back-end managed disk systems. You only need the SDDPCM to support the SVC, not the back-end devices. For the most part, SVC has not dropped support for any level of previously supported OS or multi-pathing software.
On SVC, when we migrate volumes (vDisks) from one storage pool to another, we would like to throttle this process during FlashCopy.
Yes, we had several requests like this, which is why we now recommend using Volume Mirorring to perform migrations. In fact the GUI wizard uses Volume Mirroring by default when migrations are performed. As for throttling, IBM has implemented "I/O Priority Manager" that offers Quality of Service classes for DS8000 and XIV Gen3, and might consider porting this to other products in our portfolio.
Sizing systems is an art. I just need to know if the DS8000 is running hot. Can we have the equivalent of "red lines" for our disk systems similar to automobile engines?
Storage Optimizer was added to TPC 4.2 to help in this area, identifying heat-maps for IBM DS8000, DS6000, DS5000, DS4000, SVC and Storwize V7000. We recommend you look at the performance violation reports.
How can we evaluate the characteristics of our workloads?
Yes, TPC can do this.
When we are replacing non-IBM storage with IBM, we don't have good tools to evaluate the non-IBM equipment. What is IBM doing for this?
IBM's Disk Magic modeling tool can take inputs from a variety of sources, including iostat from the servers themselves. You can also install a 90-day trial of TPC to help with this.
We really like EMC's "Grab" program, does IBM have one also?
Updating the Host Attachment Kit (HAK) for AIX is quite painful for the SVC. We prefer the method employed for the XIV.
Thanks for the feedback.
For SVC, we need to correlate disk with VMware and VIOS. Can we get vSCSI information on VIOS?
TPC 5.1 has this support, and we believe it has been retrofitted to TPC 4.2.2 Fixpack 2, coming out this month.
Currently, with SVC, when volumes are part of a Global Mirror (GM) session, we need to cancel GM, expand the source volume, expand the target volume, then restart GM. We would like this to be fully automated and non-disruptive.
Sounds like a great requirement to submit for the RFE process.
Can we get an RSS Feed for the RFE community.
Yes, you can subscribe to it. You can also set up "Watch Lists".
Thanks to all of the IBM experts on the panel for their participation at this event!
Earlier this year, I wrote a Web article titled [Data Footprint Reduction] which covered data deduplication and compression, and was asked to present this at IBM Edge. I have expanded it to include:
Space-Efficient Point-in-Time copies
After I presented the basic concepts, Sanjay Bhikot, a Unix and Storage admin at RICOH, presented his real-world experiences with data deduplication using the IBM ProtecTIER and real-time compression Beta experience using the SAN Volume Controller (SVC).
IBM Active Cloud Engine Implementation on IBM SONAS 1.3 and IBM Storwize V7000 Unified
John Sing (IBM) presented the latest enhancements in the v1.3.2 release of SONAS and Storwize V7000 Unified.
Introducing VMware vSphere Storage Features
Fellow blogger Stephen Foskett presented this session on VMware's storage features. This included VMware APIs for Array Integration (VAAI), VMware Array Storage Awareness (VASA), vCenter plug-ins, and a new concept he called "vVol" which de-multiplexes the "I/O Blender" that server hypervisors do by tagging individual requests to individual OS guests to provide added benefit. IBM is a leading reseller of VMware, so it makes sense that most of our storage meets all of Steve's requirements for recommendation.
IBM's Storage Strategy in the Smarter Computing Era
Last year, I presented this on the fourth day of the conference, and feedback we received from attendees was that this should have been presented sooner in the week, as it provides great context for the more detailed product presentations.
To address this concern, the IBM executives presented IBM strategy on Monday's keynote session, but allowed me to present this on Wednesday for several reasons:
You may have missed the keynote session. For example, you may not have arrived in time to hear the executives speak due to weather or mechanical problems causing travel delays.
You may have attended the keynote session, but want to hear it again. Maybe you were a bit hung-over, or just may have been overwhelmed with the size and scope of this event. I have read for strategic topics, audiences may have to hear the message five to seven times before they truly appreciate and understand it.
You may want to ask questions, and explore the implications in more detail. While keynote sessions can reach a broader audience, the communication is very much uni-directional. With break-out sessions with a few hundred people, the venue is more intimate and can afford opportunties for information exchange.
The title of this session rolls off the tongue nicely, much like "James and the Giant Peach", "Harold and the Purple Crayon", or "Charlie and the Chocolate Factory".
When people say they are interested in "Cloud Storage", what exactly do they mean. After discussions with hundreds of clients, IBM has worked out a "taxonomy" that identifies four distinct types of storage:
In this session, I presented how IBM SONAS addresses all four of these categories, as well as other IBM storage products that can address specific categories in the taxonomy.
In the evening, the attendees at IBM Edge joined the attendees from Innovate2012 (focused on IBM Rational products) at SeaWorld, with BBQ dinner, rides, Shamu the whale show, and a concert featuring Foreigner!
Well it's Tuesday again, and you know what that means... IBM announcements! Yesterday, at the IBM Edge conference here in Orlando, Florida, IBM announced its new apporach to storage, and a whole bunch of storage products, enhancements, and services. I will focus on some key ones here, and save the rest for next week.
IBM SAN Volume Controller (SVC) v6.4
The SVC is IBM's enterprise-class storage hypervisor. The latest software release, v6.4, can be installed on any SVC hardware, from the 2145-8F2 introduced back in 2005, to newer models like the 2145-CG8. Here are the key features:
Fibre Channel over Ethernet (FCoE) -- This is complete end-to-end support. For SVC units with 10GbE ports, these ports can be now be used for FCoE. This allows hosts to attach to SVC via FCoE, allows SVC node-to-node communication for clustering, and allows SVC to communicate to back-end devices via FCoE.
Real-Time Compression -- IBM ported over the patent Random Access Compression Engine (RACE) from the Real-Time Compression Appliances to SVC v6.4. This allows primary data, accessed via block-based protocols, to be compressed up to 80 percent. This feature is an extra priced feature by TB.
Non-Disruptive Volume move between I/O Groups -- If you don't already have SVC, you don't need to worry about this. For existing SVC customers, this allows volumes to be associated with two or more I/O groups, and that you can add or remove I/O groups non-disruptively. For example, if you want to move a volume from IOG1 to IOG2, then you add IOG2 to the list of I/O groups for the volume, let the multi-pathing software discover the additional paths, the remove IOG1, which then marks the previous IOG1 paths inactive. All this can be done while applications read and write data.
Dedicate FCP ports for Replication -- If you activate the two 10GbE Ethernet ports for FCoE, you can free up two FCP ports that you can dedicate for long-distance Metro Mirror or Global Mirror.
If you have SVC today, but are running an old release like v4.3 or v5.1, I recommennd you upgrade up to at least v6.2.05 release now. This release has been out for a year and is very stable, and serves as a great platform for a later upgrade to SVC v6.4.
IBM Storwize V7000 v6.4
The Storwize V7000 is IBM's midrange storage hypervisor. The latest software release, v6.4, can be installed on existing block-only Storwize V7000 units in the field. The Storwize V7000 v6.4 gets all the features listed above, as well as the following:
Four-way clustering -- Previously, you could cluster two Storwize V7000 controller enclosures together (4 canisters total). To cluster three or four controllers required an RPQ. Now, IBM supports up to four Storwize V7000 controller enclosures (8 canisters) without an RPQ.
Direct Fibre Channel attach -- A lot of people are using Storwize V7000 inside single-rack configurations, so it makes sense not to require a SAN switch for just a few Windows, Linux or VMware servers. An RPQ is now available to allow this to happen.
IBM Tivoli Storage Productivity Center (TPC) v5.1
TPC is already ranked one of the best Storage Infrastructure Management software in the market, and this release will just solidify its lead. Key features include:
Upward integration to higher level management systems
A new, intuitive, easy-to-use web-based GUI inspired by the XIV GUI
Integration of COGNOS to be able to generate and customize reports
Support for SONAS systems
There are several presentations on TPC this week that will go into more detail. Check out the [TPC Facebook page].
My latest book Inside System Storage: Volume IV is now available!
Yes, can you believe it? I have published my fourth volume in my "Inside System Storage" series! It is available in three formats:
Hardcover with dust jacket
eBook (Adobe Acrobat PDF)
You can order this, and all my other books, in all formats, directly from my [Author Spotlight] page. The paperback will also be available soon from other online booksellers, search for ISBN 978-1-105-72213-4.
IBM DS3500 Express
The DS3500 is our entry-level block-based device, designed specifically for random I/O workloads. This includes databases, email repositories, traditional business applications, and on-line transactional workloads. Here are the new features:
Dynamic Disk Pooling, similar to what XIV does to reduce disk rebuild times, but using a RAID-6 like approach per chunk of data.
Thin Provisioning using Dynamic Disk Pooling
Asynchronous Logical Unit Access (ALUA) failover
Enhanced FlashCopy, improved scalability, consistency groups and rollback support
VMware API for Array Integration (VAAI) support. This includes Write Same, Extended Copy, and Atomic Test & Set.
The DS3500 replaces the previous models of DS3200, DS3300 and DS3400 models.
The DCS3700 is our entry-level/midrange block-based device, replacing the DCS9900 model, designed specifically for sequential I/O workloads. This includes Big Data analytics, Hadoop, High Performance Computing (HPC), video surveillance, and television broadcasting. It holds 60 drives in a 4U controller enclosure.
This week, I am in Orlando, Florida presenting, blogging and tweeting at the IBM Edge conference. The first day began with opening main tent sessions. Deon Newman, IBM VP of Marketing, was the emcee. The four-person [Bella Electric Strings] rocked the house with some electric violins.
Game Change on a Smarter Planet: A New Era in IT
Rod Adkins, IBM Senior VP for the Systems and Technology Group, presented IBM's Smarter Computing strategy. For those not familiar with this, a little context might help.
Back in 2008, IBM launched its corporate-wide strategy called "Smarter Planet", which focused on solving the world's biggest problems through the effective use of Information Technology. To get there, everything needs to be instrumented to monitor and gather information, interconnected with centralized processing, and analyzed through intelligent algorithms.
Over the past few years, this general approach has been made more specific to tackle problems in particular industries. Detailed approaches like Smarter Cities, Smarter Energy, Smarter Education, Smarter Retail, Smarter Water and Smarter Food, are a few examples of this.
As IBM pursued solutions in each of these areas, clients realized they needed some guidance on the underlying IT infrastructure needed to deploy these solutions. Last year, IBM launched the Smarter Computing, which I [explained in great detail in my blog post last March].
Designed for the Data - to be fair, IBM systems have always been designed for the data. When the System/360 first came out, the bulk of data was stored in structured databases, so systems were designed for this. Today, over 80 percent of data is unstructured, not in a database, so the design and approach for systems today must reflect that new reality. For example, Big Data analytics is often used against spreadsheets, documents, social media feeds, and other unstructured sources.
Workload-Optimized Systems - There are two ways to have a workload-optimized system. The first is to start with general purpose components and tune them, and the second is to integrate expertise into the design.
Managed with Cloud technologies - Cloud computing has introduced new levels of standardization, automation and virtualization.
Rod wrapped up his session discussing the IBM PureSystems family of expert-integrated systems that IBM announced in April. This includes the PureFlex infrastructure system and the PureApplication platform system.
A New Approach to Storage
Brian Truskowski, IBM General Manager for System Storage and Networking, presented IBM's new approach to storage to support Smarter Computing environments.
Efficient by Design - Storage needs to be designed for the data, to store it efficiently, and be able to scale in the expected growth, driven by trends such as Big Data analytics.
Self-Optimizing - Storage needs to be self-optimizing for their particular application workloads, to avoid manual performance tuning efforts. Policies to handle Qualities of Service help optimize performance and costs based on business requirements.
Cloud Agile - Storage needs to be part of a virtualized environment, managed by Cloud technologies. This includes working seemlessly in environments with server hypervisors, storage hypervisors, virtual LANs, SANs and tape libraries.
With this new approach, clients will be able to increase competitiveness, while reducing both capital and operational expenses.
Yoni Cohen is the founder and CEO of Snowball Studios. They started with five artists, and grew to 60 people in a few years to take on bigger projects. They produce digital animation for television shows and commercials.
Despite their small size, they have a dedicated "IT" department. In addition to developing in-house tools for the artists to produce animation, they also were tasked to find the best storage solutions. Files storing 3D video can be quite large. After exhausting research into all the storage options, they chose IBM, and complemented this with the Real-Time Compression appliance for their NAS environments.
The results were stunning. A project that took 417GB before took only 148GB. a 64 percent data footprint reduction! He found he got this 3x reduction across his environment.
University of Rochester Medical Center (URMC)
University of Rochester is in New York state, about 60 miles east of Buffalo, and 90 miles from Toronto across Lake Ontario. Six years ago, Rick Haverty joined URMC as the Director of Infrastructure services, managing 130 of the 300 IT personnel at the Medical Center. I met Rick last year, when he presented at the [IBM Storage Innovation Executive Summit] in New York City. Last December, I co-presented with Rick on a session for SONAS at the [Data Center Conference].
URMC has DS8000, DS5000, XIV, SONAS, Storwize V7000 and is in the process of deploying Storwize V7000 Unified. He presented how he has used these for his Vendor Neutral Archive (VNA). For Rick, the IT Infrastructure has become the new "dial tone", everyone expects it to work 100 percent of the time.
For those not familiar with VNA, Rick has 36 different departments, and each was storing archives of their medical images in separate silos of storage. Using software from [Acuo Technologies], he was able to have all 36 different PACS systems store data onto a single storage repository. The side benefit is that all medical images are now readily available to the Electronic Medical Records (EMR) system.
Main Tent for Technical Edge
After the opening session, the folks in Technical Edge moved to a different room for the main tent session. Mike Kuhn, IBM VP of Systems Lab Services, was the emcee. There were three guest speakers:
Clod Barrera, IBM Distinguished Engineer and Chief Technical Strategist for IBM System Storage, presented on storage trends and directions, and how this will influence workload-optimized systems, Cloud computing, Easy Tier, and Active Cloud Engine.
Jeff Jonas, IBM Fellow and Chief Scientist for IBM Entity Analytics, presented "Fantasy Analytics" which explained his work in the Business Analytics. He used "jigsaw puzzles" as an analogy to help explain for the type of work he is researching.
Dan McMillan, Chief Comedy Officer of his own company, was formerly an engineer, but now stand-up comedian. He poked fun at the IT industry, how things have changed since he was an engineer, and his ideal "Universal Business Translator".
Well, it's Wednesday, and you know what that means... IBM Announcements!
(Actually most IBM announcements are on Tuesdays, but IBM gave me extra time to recover from my trip to Europe!)
Today, IBM announced [IBM PureSystems], a new family of expert-integrated systems that combine storage, servers, networking, and software, based on IBM's decades of experience in the IT industry. You can register for the [Launch Event] today (April 11) at 2pm EDT, and download the companion "Integrated Expertise" event app for Apple, Android or Blackberry smartphones.
(If you are thinking, "Hey, wait a minute, hasn't this been done before?" you are not alone. Yes, IBM introduced the System/360 back in 1964, and the AS/400 back in 1988, so today's announcement is on scheduled for this 24-year cycle. Based on IBM's past success in this area, others have followed, most recently, Oracle, HP and Cisco.)
Initially, there are two offerings:
IBM PureFlex™ System
IBM PureFlex is like IaaS-in-a-box, allowing you to manage the system as a pool of virtual resources. It can be used for private cloud deployments, hybrid cloud deployments, or by service providers to offer public cloud solutions. IBM drinks its own champagne, and will have no problem integrating these into its [IBM SmartCloud] offerings.
To simplify ordering, the IBM PureFlex comes in three tee-shirt sizes: Express, Standard and Enterprise.
IBM PureFlex is based on a 10U-high, 19-inch wide, standard rack-mountable chassis that holds 14 bays, organized in a 7 by 2 matrix. Unlike BladeCenter where blades are inserted vertically, the IBM PureFlex nodes are horizontal. Some of the nodes take up a single bay (half-wide), but a few are full-wide, take up two bays, the full 19-inch width of the chassis. Compute and storage snap in the front, while power supplies, fans, and networking snap in the back. You can fit up to four chassis in a standard 42U rack.
Unlike competitive offerings, IBM does not limit you to x86 architectures. Both x86 and POWER-based compute nodes can be mixed into a single chassis. Out of the box, the IBM PureFlex supports four operating systems (AIX, IBM i, Linux and Windows), four server hypervisors (Hyper-V, Linux KVM, PowerVM, and VMware), and two storage hypervisors (SAN Volume Controller and Storwize V7000).
There are a variety of storage options for this. IBM will offer SSD and HDD inside the compute nodes themselves, direct-attached storage nodes, and an integrated version of the Storwize V7000 disk system. Of course, every IBM System Storage product is supported as external storage. Since Storwize V7000 and SAN Volume Controller support external virtualization, many non-IBM devices will be supported automatically as well.
Networking is also optimized, with options for 10Gb and 40Gb Ethernet/FCoE, 40Gb and 56Gb Infiniband, 8Gbps and 16Gbps Fibre Channel. Much of the networking traffic can be handled within the chassis, to minimize traffic on external switches and directors.
For management, IBM offers the Flex System Manager, that allows you to manage all the resources from a single pane of glass. The goal is to greatly simplify the IT lifecycle experience of procurement, installation, deployment and maintenance.
IBM PureApplication™ System
IBM PureApplication is like PaaS-in-a-box. Based on the IBM PureFlex infrastructure, the IBM PureApplication adds additional software layers focused on transactional web, business logic, and database workloads. Initially, it will offer two platforms: Linux platform based on x86 processors, Linux KVM and Red Hat Enterprise Linux (RHEL); and a UNIX platform based on POWER7 processors, PowerVM and AIX operating system. It will be offered in four tee-shirt sizes (small, medium, large and extra large).
In addition to having IBM's middleware like DB2 and WebSphere optimized for this platform, over 600 companies will announce this week that they will support and participate in the IBM PureSystems ecosystem as well. Already, there are 150 "Patterns of Expertise" ready to deploy from IBM PureSystem Centre, a kind of a "data center app store", borrowing an idea used today with smartphones.
By packaging applications in this manner, workloads can easily shift between private, hybrid and public clouds.
