A freshly printed IDC White Paper shows how the recent XIV Gen 3 changes have pushed it from Tier 1.5 into the Full Tier 1 space.
Prior to now XIV was a disruptive technology.... well yet another Storage Inflection point has been breached.
Hang onto your legacy vendors no more... prepare for XIV Gen 3 (GA March '12)

Let's talk @ your IBM Storage today!
We have kicked around the term Easy Tier for a few weeks now and thought it was time to dissect the technology in detail.
What is IBM Easy Tier? It is an easy tool (setup in 15-30 minutes) that was designed to optimize data placement in a hybrid extent pool (Mix of SSD & HDD). Understand that it is a 2-tier architecture for data (hot & cold data sets) and that all candidate data is reviewed at the extent level (sub-volume level) for movement with-in the hybrid pool. The two tiers can be either SSD+FC or SSD+SATA drive types.
IBM Easy Tier is a free tool available on the DS8700, DS8800 (LIC code level requirements etc) & Storwize V7000 subsystems (Soon to be available on SVC via code set v6.1. Under the covers Easy Tier is a continuous learning algorithm that should have 24 hours (A.K.A Workload learning) of data prior to making recommendations. The algorithm can bring benefits to day-to-day workloads as well as the end of the quarter and year end workloads can
There are currently two modes to Easy Tier (Automatic & Manual Modes).
Easy Tier Automatic Mode enables facilities to autonomically optimize data placement among physical resources with different granularity, performance (and cost) characteristics.
In manual mode allows you to manually merge extent pools and relocate volumes
Other Easy Tier features – is fully aware of Copy Services (FlashCopy, MM/GM)
Oh, did I mention the price? It is FREE!

The IBM Storage Tier Advisor Tool predicts whether the addition of Solid State Drive (SSD) capacity in conjunction with the Easy Tier function could benefit system performance.
The IBM Storage Tier Advisor Tool is a Windows console application that analyzes heat data files produced by Easy Tier and produces a graphical display of the amount of "hot" data per volume and predictions of how additional Solid State Drive (SSD) capacity could benefit performance for the system and by storage pool. This version of the Storage Tier Advisor Tool supports heat data files produced by Easy Tier on SAN Volume Controller 6.1, Storwize V7000 and DS8000 5.1, 5.1.5.
Heat data files are produced approximately once a day when Easy Tier is active on one or more storage pools and summarize the activity per volume since the prior heat data file was produced. On SAN Volume Controller and Storwize V7000 the heat data file is in /dumps on the configuration node and is named "dpa_heat.node_name.time_stamp.data". Any existing heat data file is erased whenever a new heat data file is produced. The file must be off-loaded by the user and Storage Tier Advisor Tool invoked from a Windows command prompt console with the file specified as a parameter. The user can also specify the output directory. The Storage Tier Advisor Tool creates a set of html files and the user can then open the resulting "index.html" in a browser to view the results.
Usage information can be found in a readme supplied with the Tool.

IBM’s new mid-range Scalable Storage Storwize V7000 was designed from the ground up offering ease of use for product install, Admin & Maintenance. Take notice the product is new, however, the code set it runs on is stable it is based on IBM’s SVC which is > than 6.5 years young. The subsystem also brings enterprise caliber technology into the mid-range market. Such as, Disk Virtualization (based on SVC technology) RAID technology brought out of our DS8000 family and ease of use GUI from the XIV family. All features available to help your enterprise become successful with out worrying about watered down feature sets.
Let’s run through some of the Enterprise Offerings:
1) SVC + Disk Virtualization, 2) RAID technology from DS8K including Atomic Update, 3) Ease of use from XIV 4) Easy Tier
Maintenance Procedures (DMP) to help in maintenance & recovery tasks 6) Embedded e-learning video’s 7) Presets (AKA
Templates) helps in ease of use and simplify repetitive tasks
8) Replication (Async or Sync) over IP or Fibre Channel or 9) Mirroring via (MM/GM) 10) Thin Provisioning, 11) SnapShots w/ plug-in capabilities for FlashCopy Manager (FCM) and the last item I will cover is DR Automation (FO, FO back, Full site switching) – true mature enterprise technologies not watered down solutions
But, know that as you dig into this extensive product offering you will see many more options.
Oh, I just can’t help myself, I need to let you know about the 45 days of free disk migration to help get you off that other gear!
Isn’t it time to discuss your mid-range disk business with IBM?

Solid State Drives (SSD)
We all are aware of the hundreds of articles at blogs raving about how the performance in / around SSD is going to transform the storage industry. I am not going down that rabbit hole; I am however, going to present another angle all together. Have you considered how many SSD’s your disk subsystem can support without bringing it (disk subsystem) to its virtual knee’s? You must understand, it is one thing to support SSD’s (say as a RFP checklist response and it is quite another to have them operate in your Tiered ILM with out negatively impacting disk subsystem performance).
Have you considered how did the disk subsystem architecture changed to support the SSD’s? Was the disk subsystem powerful enough to support SSD’s before their implementation? What is an optimal utilization to run a disk subsystem at with SSD’s? What is an optimal SSD utilization rate (is it 30%, is it 50% or >)? What application will you run on SSD? What business unit will want to run their application on SSD’s (besides all of them)?
What critical thinking have you been through to get to the nuts and bolts of how this technology will impact your enterprise?
