Anthony's Blog: Using System Storage - An Aussie Storage Blog
I was recently asked to travel to Taiwan to teach a Storwize V7000 class.
I have done a fair amount of travel with IBM, but this was my first visit to Taipei.
I must say I loved the energy and enthusiasm of the place.
While there I taught a new course: Storwize V7000 Implementation (SSE01)
For those who are familiar with IT education, IBM Systems and Technology Group (STG) Education comes in 4 forms:
1) Lecture Only
2) Lecture with simulated labs
3) Lecture with remote remote labs
4) Lectures with local labs
This particular course is the third type, meaning it consists of lectures combined with remote labs.
This means we connected via VPN to actual machines located in Raleigh, North Carolina.
We had access to multiple pods, where each pod has its own Storwize V7000, plus a DS3400, SAN switches and hosts running AIX and Windows.
In addition IBM Taiwan secured a demonstration Storwize V7000 for us to have in the classroom (to see and touch and do initial config on).
This was the first time the course had been offered in Taiwan and everyone was very excited to be part of it.
The agenda looked something like this:
• Unit 1 - Introduction to the IBM Storwize V7000
• Unit 2 – Enclosures and RAID Arrays
* Labs: initial config, accessing the GUI and CLI, configuring internal and external storage and defining attached hosts
• Unit 3 – Fabric Zoning
• Unit 4 – Thin provisioning and Volume Mirroring
• Unit 5 – Data Migration Facilities part 1
* Labs: Accessing storage from AIX and Windows hosts via fibre channel and iSCSI, Easy Tier Part 1, migration part 1
• Unit 5 – Data Migration Facilities part 2
• Unit 6 – Easy Tier
• Unit 7 – Managing IBM Storwize V7000
* Labs: Migration part 2, Thin provisioning, RAID options, Easy Tier part 2
By the conclusion of the course the students had had many hours enjoying the new GUI, which I thought was really important.
Hands on operation of a system is the best way to learn.
Those that already knew SVC found the course quite easy, but everyone felt that they had learnt a lot.
The chance to use Easy Tier and do a live migration was really important.
I certainly enjoyed teaching the course and look forward to teaching it again!
For those who live in Australia, yes we are going to offer the course locally.
As soon as I have dates I will share them with you.
If your using Microsoft Windows hosts with XIV, there are minimum required Microsoft hotfixes.
They are listed in the Host Attachment Kit (HAK) 'release notes found here: HAK Release Notes
However I have learnt that some additional fixes are recommended, particularly if your planning an XIV firmware update:
•Windows 2003: http://support.microsoft.com/kb/950903
•Windows 2008: http://support.microsoft.com/kb/983554
So please check your systems to see if these hotfixes are installed.
If not, you should plan to schedule them on your next patch Tuesday.
I have noticed something suspicious on the developerWorks forum.
Updates are coming from new users where:
Their posts always come in one of three flavours.
1) They create posts with comments like "Thanks for sharing". Here are some examples:
2) They may instead complain about broken links (which are NOT broken), such as these two:
3) Finally, they may kind of ask a question, but without really referring to the material they reference, such as these:
I have sent messages to the majority of these 'people', but so far they have NOT responded, nor do I expect them to.
My long term plan is to simply delete their posts and ban their user ids.
What are they up to? I don't know.
But given that none of their posts ADD anything to the DW forum, I have no fear in REMOVING them.
So I have three requests from my audience:
It could be that I have become unnecessarily paranoid, but this pattern seems to be rather strong.
A final blog entry before Christmas, with a little Christmas present for all our midrange storage users.
The IBM System Storage Interoperation Center (SSIC) found here now lists all of IBMs LSI based
Midrange and Entry Disk systems. So you can now select VMware vSphere/ESX 4.1...
and then find products like the DS4700 and DS4800.
As you can see, the DS4700 has 5808 different configuration results, so hopefully your environment is in there.
If your environment is still not listed, please contact your IBM FTSS or Business Partner to ask for a SCORE request to get support.
Its been over a week since the Sydney Storage Symposium finished and I now have the feedback results.
The symposium itself was a great success and was a fully booked event (a full house!).
We ran 48 separate sessions across two and a half days,
all of them focused on storage and how IBM provides solutions for this space (including things like Cloud and DR).
These included many lab sessions on SVC, TPC and XIV.
Sessions were also given by IBM partners including Brocade and Qlogic.
In addition Brocade, Qlogic and LSI each manned a vendor stall to share information about their products.
And to top this off, Alexis Giral from the IBM Storage Pre-Sales team in Sydney
manned a Storwize V7000 demonstration stand for the entire event.
Attendees were able to see, hear, touch and most importantly play with, an actual Storwize V7000.
Feedback was sought from every attendee for every session. Feedback was also sought for the entire Symposium.
Of the sessions, the majority scored a net satisfaction rating of 100% (which is an excellent result).
The overall satisfaction rating for the conference was 99%.
The most popular session was: "Introducing the Storwize V7000"
Some of the feedback given across all of the sessions included:
Some of the suggestions given for future symposiums included:
I personally presented four different presentations, which were:
The last session listed (SAN Best Practices) was my favourite. The room was packed to over flowing
and the audience was very interactive.
So with all of this feedback and experience under our belts we can begin planning for the 2011 event.
In 2011 we will be holding another IBM System Storage event, this time in Melbourne, so watch this space for more updates.
Its been a busy week!
We just completed our first IBM System Storage Symposium in Sydney.... and it was a great success.
Thanks to everyone who attended and presented.
Meanwhile... there are quite a few updates to the IBM Support site, and as usual Rob Jackard from the ATS Group
has created a great summary which I will reproduce here.

IBM has published Storage Performance Council (SPC) SPC-2 sequential workload benchmark results for the System Storage DS8800.
The measured throughput of 9,705.74 SPC-2 MBPS™ (9.7 gigabytes per second) leads all other published SPC-2 results!
Its interesting to compare this result with the DS8300 results posted in 2006.
What it shows is how the introduction of new technology like Power-6, PCI-E and SAS v2
combined with the underlying architecture of the DS8000, has proved a winning combination.
