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!
Well, it's Tuesday again, and you know what that means... IBM announcements!
Last week, IBM had a big storage launch of various products, with the June 4 announcements at the IBM Edge 2012 conference. I provided highlights in my post [IBM Edge Announcements]. As promised, here are the rest of the announcements.
SONAS v1.3.2 adds support for management by the newly announced IBM Tivoli Storage Productivity Center v5.1 release. Also, IBM now officially supports "Gateway configurations" that have the storage nodes connected to XIV or Storwize v7000 disk systems. These gateway configurations offer new flexible choices and options for our ever-expanding set of clients.
ProtecTIER appliances and gateways
IBM ProtecTIER line of data deduplication appliances and gateways add CIFS file system support. Rather than using OST or a VTL interface, you now have CIFS as a new option for host attach. Also, IBM introduces the new TS7620 Express model, with options for 5.4TB and 11TB in capacity, replacing the previous TS7610 entry level.
LTFS Storage Manager
The Linear Tape File System (LTFS) allows files to be stored on tape cartridges in a manner that allows them to be mounted as file systems, much like a USB memory stick. The new LTFS Storage Manager software allows you to manage a collection of files across a set of cartridges, moving files from one cartridge to another, consolidating valid data onto fewer cartridges, and removing files no longer needed. This is sometimes referred to as "lifecycle management".
Tape System Library Manager
When IBM first introduced the "shuttle" that allowed up to fifteen TS3500 tape libraries to be connected together into a single system, only HPSS customers could take advantage of this. Software was required to coordinate the movement of cartridges from one library to another. The new IBM Tape System Library Manager now offers an alternative to HPSS for coordinating this activity.
DS8000 v6.3 microcode
IBM now offers 400GB solid-state drives. IBM's market leading support for Full Disk Encryption (FDE) is now extended to cover all drive speeds, from the slowest 7200RPM NL-SAS drives up to the fastest solid-state. IBM Easy Tier extends its super-easy implementation to work across all three of these tiers including encryption.
IBM now offers implementation services for IBM XIV Gen3 storage system, and the N series models 3220 and 3240.
This week I am on the road visiting various clients. Next week, Moscow Russia for the "Edge Comes to You" event!
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!
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.
I presented IBM's Smart Archive strategy and the storage products IBM offers to archive data and meet compliance regulations:
The differences between backup and archive, including a few of my own personal horror stories helping companies who had foolishly thought that keeping backup copies for years would adequately serve as their archive strategy
The differences between Write-Once Read-Many (WORM) media, and Non-Erasable, Non-Rewriteable (NENR) storage options.
How disk-only archive solutions become "space heaters" for your data center.
An overview of the various storage hardware options from IBM.
An explanation of the different IBM software offerings to help complement the storage hardware choices.
IBM TotalStorage Productivity Center (TPC): New Features and Functions
Mike Griese, IBM program manager for TPC, presented the latest in TPC 5.1 version announced this week. His session was organized into four key sections:
Insights - TPC 5.1 integrates COGNOS reporting, which allows custonmization of reports and ad-hoc exploration and analysis. Since the reports are not binary-compiled into the product, IBM can ship new COGNOS reports as templates outside the normal TPC release schedule. Also, TPC 5.1 got smarter on reporting on server virtualization hypervisor environments to avoid double-counting.
Recommendations - TPC 5.1 can analyze your usage patterns across the entire data center and make recommendations to move data from one storage tier to another. You can then act on these recommendations by moving data from one tier to another, either "up-tier" to faster storage, or "down-tier" to less expensive storage, using a storage hypervisor like IBM SAN Volume Controller. This is complementary to features like Easy Tier which optimize within a single disk system.
Performance - TPC 5.1 uses a new web-based GUI, based on AJAX, HTML5 and Dojo widgets, inspired by the IBM XIV GUI, and similar to the web-based GUI of SAN Volume Controller, Storwize V7000 and SONAS.
Mike also explained the new TPC 5.1 packaging. Instead of having a variety of components like "TPC for Disk", "TPC for Data", and "TPC for Replication", the new packaging simplifies this down to two levels of functionality. The basic level supports block-level devices, including disk performance, replication and SAN fabric management. The advanced level adds support for files and databases, including support for Cloud management such as SONAS environments.
Dan Zehnpfennig, Solution Architect, talked about his experiences installing TPC 5.1 and how this was much improved over previous TPC versions.
