- You need your XIV GUI to be on version 2.4.4 and you need your XIV to be on code version 10.2.4.
If your not on those levels, you will need to upgrade before you can use this feature.
The GUI is easy, just get it from here. The XIV code needs to be upgraded by IBM.
Talk to your local IBM Rep if you need to get this done.
- You can control all aspects of QoS using xCLI.
Why is this cool?
Consider this idea:
Script the movement of hosts into and out of performance classes on a regular basis.
You could have pre-set bandwidth levels based on time of day, or day of week or end of month.
- This feature lends itself to multi-tenancy.
By setting a maximum bandwidth value on each tenant, you can ensure that each tenant gets a fair share of the grid.
Anthony's Blog: Using System Storage - An Aussie Storage Blog
After a chat with my one of our business partners, I thought I would add some more info about XIV and QoS:
I spent the first week of my recent vacation in Sydney (I live in Melbourne).
For someone who has spent many weeks in Sydney on business, this was the first time I actually went there as a real tourist.
First up, it was a great break and my family and I can heartily recommend Sydney to anyone (from any part of the world) who is looking for a "holiday with the lot".
As part of our planning, we clearly had a budget to work to as well as many idea about things to do.
Of course one of the big considerations was where to stay. I did a great deal of Googling around but relied on TripAdvisor heavily to help make our final decision.
I really love tripadvisor for two reasons:
So what has that go to do with IT? Well those who follow storage blogs will have seen a spike recently in discussions on two subjects:
I hope that its obvious that I work for IBM, so I accept that you may choose to view anything I say as potentially coloured by my relationship with my employer.
It has left me pondering where clients should go to get a good handle on what really matters most to them.
To chose the hotel that best matched my holiday requirements I used TripAdvisor.
But what can clients do?
I personally read many vendor and 'independent' blogs to try and ensure my 'world view' is as realistic and informed as possible.
There are some great blogs out there, but I do not know many of these people or their organizations personally. So I always read them through a haze of mild cynicism.
So is there a TripAdvisor for Storage IT? A place for genuine end-users to share their experience with specific solutions?
I have to say that XIV is one product that is crying out for such a beast. My experience is that client satisfaction levels with their XIVs is remarkably high but is that always reflected on the Web?
So far the best place I have seen for shared experiences from 'real' people is the XIV group on LinkedIn.
It would be great to see more actual end users head over there and contribute (so please do!).
Finally I should also point out that if there is a business relationship between IBM (my employer) and TripAdvisor or Linked In, I am not aware of it.
My opinions on these organizations are totally my own.
And the hotel we stayed in? The Quay Grand on Circular Quay. The view from our balcony was priceless. Check it out:
So first up, I have been on leave for two weeks... thus my stunning silence
The good news is that I had a great break, the bad news was the size of my inbox on return
So for those of you who read my blog entry titled:
10 things I like about the IBM DS3500https://www.ibm.com/developerworks/mydeveloperworks/blogs/anthonyv/entry/10_things_i_like_about_the_ibm_ds35002?lang=en
I now have reason number 11:
11. You can power it up with NO drives inserted and you can make configuration changes with only ONE drive inserted.
So why is this good?
The DS3200/DS300/DS3400 range has a requirement that four drives be installed before you power the box on, or configure it.
This means the smallest config you can order has to have four drives in it.
The DS3500 has removed that requirement, meaning you can order and build a machine with only one disk drive.
IBM documentation is in the process of being updated to reflect this.
If your a user of XIV, or your considering purchasing an XIV, then there is one tool that you will truly love. It's called XIVTop. The XIVTop application comes packaged with the XIV GUI and is one of the handiest add-ons I have ever seen. It lets you monitor your XIV in real time, seeing exactly how much IO or throughput is being achieved and at what response time (in milliseconds). You can immediately answer questions like:
The ability to get this information in real time is what makes XIVTop so invaluable.
So in the tradition of always pushing my boundaries, I thought I would create a narrated video about XIVTop. What I discovered is just how terribly hard doing narrated videos are: You need to write a script... you need to stick to the script... you need to not fluff any words.... you need to speak slowly and clearly and not start talking in a strange accent. I had trouble with all of these, so I made take after take after take after take, until I was heartily sick of the process. I have now got a much greater respect for newsreaders and film actors. This narration stuff is hard!
So please check out my final take. It's still far from perfect, but all feedback is very welcome. The only other thing that is quite strange is Youtubes choice of videos to watch after mine. Its worth watching just to see the list. I think the term performance confuses the algorithm.
Bob Leah is one of our leading lights in the developerWorks team. His blog (found here) is a great resource for Web designers. He recently created a new set of templates to enable a mobile page for developerWorks blogs. You can read his article about the new template here.
This morning I boldly went and installed the new templates and so far I think it looks fantastic, not only on the iPhone, but also the iPad and on regular browsers. My only complaint is that I lost the banner image of my Golden Retriever (my loyal hound Suzie). Bob assures me she will reappear soon. In the meantime, I would love to hear feedback about the new template. This is what it looks like on my iPhone:

This is a great opportunity to meet and network with like minded peers at the end of year Tivoli User Group meeting. And hopefully Richard will show us a movie or two!
When IBM first released the Storwize V7000, we announced it was capable of supporting ten enclosures, but would on initial release support only five. We stated that this restriction would be lifted in Q1.
The good news is that this restriction is indeed now lifted by the release of Storwize V7000 software version 188.8.131.52, which is available for download from here:
You should also check out this link:
This new level also contains an additional enhancement which I think users will really like, called Critical Fix Notification. The new Critical Fix Notification function enables IBM to warn Storwize V7000 and SVC users if we discover a critical issue in the level of code that they are using. The system will warn users when they log on to the GUI using an internet connected web browser. It works only if the browser being used to connect to the Storwize V7000 or SVC, also has access to the Internet. (The Storwize V7000 and SVC systems themselves do not need to be connected to the Internet.) The function cannot be disabled (which is a good thing) and each time we display a warning, it must be acknowledged (with the option to not warn the user again for that issue).
Its been an interesting week in IT retractions.
Microsoft seriously went off the rails with their Meter Maid Booth Babes on the Gold Coast.
Check out the story here or here.
I mention this story not because I want to embarrass Microsoft (who I don't think quite realised what they had signed up for).
To their credit they quickly apologised and moved to correct their mistake.
Instead I mention this because several Microsoft people were more than willing to (quite rightly) publicly express their opinions on the subject.
I thought this was fantastic.
But with great power comes great responsibility.
As an IBMer I have never been told what I can or cannot blog.
However I do of course follow IBM Business Conduct Guidelines as well as IBM Social Networking Guidelines.
So I have to say that I viewed with dismay HDS blogger Pete Gerrs extraordinary attack on Moshe Yanai and the IBM XIV.
He has since rather gracelessly withdrawn the blog entry but his follow on comments need some response.
The XIV has been (and continues to be) a fantastic product for IBM.
Not only is it a great sales success, it has also allowed us to talk to clients who would not normally purchase IBM storage.
Far from damaging IBMs existing product line, it has resulted in those lines growing stronger (just wait and see).
We have a new focus on usability and simplicity, on making the experience of using and managing storage easier and smarter.
To some part, XIV has brought that focus. I personally think we needed it and that we are stronger for it.
As the year comes to a close you will see the benefits of this reinvigoration with some truly fantastic storage product announcements (across the board).
So while hopefully Pete can take some lessons from his very creditable and measured fellow blogger Hu Yoshida,
I will patiently wait for Barry Burke to post that he was wrong about DS8000.
And I will keep trying to get it right the first time.
After seeing some tweets from @SFoskett regarding XIV support for VAAI, I thought I would supply an update with the information that I have to hand.
IBM added VAAI support in XIV code level 10.2.4. However a code fix has since been written for a VAAI related issue (I don't have the details), which means that we are delaying the official support till the release of 10.2.4a code (which should be early March).
In the meantime we are also waiting for the release of the VMWare certified driver for VAAI and XIV, which should come out at the same time. So there are two dependancies.
As soon as both things are available, I will write a new post confirming this.
I have some very keen customers lined up to try it out, so I plan to blog about the results as soon as my clients have had some run time to generate meaningful stats.

Its that time of the year again - announcement time! And the May 9 set of storage announcements by IBM is one of the richest set of announcements I have ever seen. Practically every storage product has received updates with new features stretching from Tape Drives to Tape libraries to Disk system updates (from the smallest system to the largest system). We have NAS updates and we have storage virtualization updates. I struggled to decide which subject to start on, to do justice across the board. So let me first list just some of the products that have received updates:
TS1140 - Super fast, massive capacity, enterprise tape technology.
For many years IBM has been using its own technology (as an alternative to LTO) to offer clients a higher class of enterprise tape. The TS1140 is the fourth generation of this technology. Using the new JC media which has 4TB of native capacity, then presuming a compression ratio to 2.5 to 1, you could place 10 TB of compressed data onto a single cart. And you could do this at 250 MBps sustained, which according to Oracle, makes the TS1140 the fastest tape drive in the world! The TS1140 will happily burst at up to 650 MBps - so we now have a tape drive that can truly utilize a 8 Gbps fibre channel port. It reinforces the green credentials of tape by using only 46W of power and supports LTFS, the Long Term File System, which leads me to....
LTFS - Long Term File System
Speaking of LTFS, we have enhanced the LTFS standard to now support tape libraries. So get this idea.... you attach a tape library to your server. All the tapes in the library appear to the operating system as directories. You can select any of these directories and the library will open it up (i.e. mount the tape). Now the contents of the tape itself appear as a directory structure, from which you can add or remove files. In other words, the library and the tapes can be manipulated without any form of backup software sitting between you and the operating system. After the initial tape mount, the directory is locally cached, so you don't need to mount the tape again to see what is on it (and to search the directory). This whole concept has the most amazing potential use cases.
IBM has a truly fantastic tape library with the TS3500. Now we add the ability to shuttle tapes between aisles to create a larger logical library. How do you like the idea of a logical tape library that can hold 300,000 cartridges totaling 2.7 exabytes?
The IBM TS7700 is our Mainframe virtual tape library solution. It gets a major performance boost with the introduction of Power 7 servers plus many other improvements.
In terms of disk we have enhancements to the following products:
DS8000 Family with release 6.1
When we released the DS8800 last year, we committed to deliver a merged code library which would support both DS8700 and DS8800. This would ensure that they both have the same feature set. We now deliver on that commitment, plus supply an enormous set of new features and functions for both products: so both products continue to get major enhancements and updates. These include:
Easy Tier enhancements: Any two disk technologies can now be placed in a pool
V7000 and SVC Family with release 6.2
The IBM SAN Volume Controller and Storwize V7000 share a common code library, so improvements are common. In the 6.2 release we deliver the following enhancements:
Flash Copy Improvements: Allow remote copies of flashcopy targets
The DS3500 is IBM's entry level disk rocket ship. I am a huge fan of this box for clients with smaller or point solution requirements. We have enhanced the product with the following:
Double the drives: We now support 192 drives.
The DS5000 range consists of DS5020 (also sold as DS3950), the DS5100 and the DS5300. Improvements include:
Scheduled flashcopies: Gives the ability to have scheduled flashcopies run without external intervention.
I have not listed all of the product announcements. There are improvements to SONAS, our nSeries products, Information Archive, Real Time Compression device.... the list goes on.
I will write up another post with all the links....
After 3.5 years of reliable service, the 19" LCD monitor on my sons computer died... and
would not power back on. Warranty long since expired and replacement LCDs being
relatively cheap, I replaced his monitor with a 22" LCD and he happily updated his
Facebook status to suit.
Except there was a problem.... what to do with the dead monitor?
I had three choices:
But there was a further problem. This lovely sticker on the back made no mention ofROHS and made even more disturbing mentions of mercury!
What I found was this site at Sustainability Victoria, which took me to this site which told me all about a program called ByteBack. One trip to Officeworks in Dandenong later and my dead LCD was off to be recycled at no charge to myself. Not only was my shed less cluttered, but I might even have helped the environment.
I would be curious to know if other people have been able to find similar programs in their locations? If so... please let know, lets spread the word!
I think this picture speaks for itself: Three XIVs. Three cities. Three way iSCSI.
I had a great time yesterday running a one day seminar for IBM Business Partners on the Storwize V7000.
Interest was so strong we had to change locations to get a larger room... and then we had to ask for an even larger room!
It was a very positive session with lots of great questions.
A really like it when I get questions.... it means people are awake, listening, interested and more importantly THINKING.
Even more exciting: IBM announced today general availability (GA) of the new IBM Storwize V7000 mid-range disk system.
We have started shipping across multiple geographies around the world, including:
Australia, Bolivia, Denmark, Germany, India, Japan, Korea, the Netherlands, Romania, Saudi Arabia,
South Africa, Sweden, the United Kingdom and the United States.
Don't hesitate to contact your IBM Sales Rep or BP and ask for a demo.

I just got an email that I thought I would share with you.
IBM Storage have a new iPhone and Blackberry app.
I am test driving it as I type this (which is never wize... don't drive and type
You can download the IBM Storage iPhone and Blackberry apps from here:
My first impression is that the product information is going to be really handy because not only is there disk.
there are also Switches and Tape.
So please... download... supply feedback and enjoy!
Being a person who walks dogs, visits the gym and uses public transport.... I have plenty of time to listen to podcasts.
The main challenge being that while listening to a podcast.... you actually need to LISTEN.
On more than one occasion I have zoned out, missed something interesting and suddenly thought... what did he/she just say?
One podcast that is a favourite of mine is "Security Now" with Steve Gibson. You can find it here, I highly recommend it (you wont zone out while listening to it).
This weeks episode (episode 274) discusses two themes that keep cropping up again and again:
"Of course you could also just not use IE, which would be a fantastic solution"
I heartily agree with Steve and I was pleased that this year IBM chose to standardise on the Firefox browser (read that story here).
One of the stated reasons being that Firefox is more Open Standards compliant.
So its nice to see that the new Storwize V7000 (and SVC 6.1) Web based management GUI uses both of these things, in that:
This makes it a simple, safe and secure GUI that uses industry standard best practice.
Please note that you can still choose to use IE... and it will work perfectly. Its just not our recommended Browser.
Of course if you use the CLI, it will also be secured using SSH v2 public/private key encryption (as the SVC has always done).
My hearty recommendation of Steve Gibsons work, like everything I express in this blog, is my personal opinion, and not that of my employer.
