Anthony's Blog: Using System Storage - An Aussie Storage Blog
Just a short update to say that Visio Cafe has some new IBM stencils.
IBM supply the stencils to Visio Cafe who make them available free of charge to all our customers.
You can use these stencils without acknowledgement or payment.
Clearly you still need to buy Visio from Microsoft.

IBM recently announced the new System Storage DS3500 Express. The DS3500 is an entry level storage system that can be easily serviced and managed by an end-user. It is a very worthy successor to the DS3200/DS3300/DS3400 product line. So I thought I would share with you 10 things I really like about the new IBM DS3500 (in no particular order).
1) Its small
The base unit is only 2U in size and can hold either 12 of the 3.5" disks or 24 of the smaller 2.5" disks (depending on model). Each expansion drawer can also hold 12 of the 3.5" or 24 of the 2.5" disks (depending on model) and you can have 3 of them. So thats a potential 96 disks in 8U of rack space.
2) Its all SAS
In my opinion, Serial Attached SCSI (SAS) is the future of disk attachment. Traditional parallel SCSI is so 20th century and FATA didn't work out too well. I think SATA and FCAL attached disk will eventually be replaced by SAS and the DS3500 is all SAS at the disk back end and SAS by default at the host front end as well.
3) Its got flashcopy
The DS3500 can create two flashcopies without any extra licenses. I really like the fact that if your doing an OS or application upgrade, you can give yourself a quick roll-back point by just reserving some space for a flashcopy repository. This is also a great way to test whether flashcopy is right for your business and if so, buy the license to create more than 2 copies at a time.
4) Its got remote mirror
The DS3000 range up until now did not offer remote mirror capability. This meant that if you wanted a DR solution you needed to buy something to go over the top such as IBM SVC or Softek Replicator. The DS3500 now offers its own native replication that not only fills a spot but is compatible with existing DS4000s and DS5000s that you may already have in your business.
5) Its got nearline
So FATA disk may not have worked out, by nearline SAS is a far better alternative. The 2.5" model offers a 500 GB 7.2 K RPM nearline SAS drive. Or how about a 2 TB drive in the 3.5" form factor? Want some archive disk using nearline where the spindle count will still deliver good performance? Heres the solution.
6) Its green
If we accept that MAID was not the solution for the masses, the better thing is to simply do more with less, which is exactly what the DS3500 does. We are talking around 500W of power usage for a 48 disk two drawer solution (with 2.5" disks). Thats around half the power consumption of the equivalent model with 3.5" disks. This means less power drawn in and less hot air blown out.
7) One model to rule them all
The DS3500 comes in one model: SAS. You want fibre channel? No problem, just add the card. You instead want iSCSI? Same deal, just add the card. All models retain the SAS adapters which are proving so popular in the rack and blade server space.
You need a point solution to provide data-at-rest encryption? Here it is with 300 GB and 600 GB Self Encrypting drives that protect your data with no performance impact. Even better is that the software to manage encryption is rolled into the DS Storage Manager. Talking of which...
9) Easy Management
The DS3500 continues to use an intuitive and easy to use GUI which now includes all the dynamic volume management. This is an improvement over previous models where this had to be done via command line.
10) Its cheap
Being entry level it is priced for that market. You could also place it behind the SVC for a quick encryption solution or as a VDisk mirror repository.

Here is a list of all the IBM Asia Pacific and Japan Announcement Letters that were released on May 9. They are in several sections:
There are several withdrawals, but these are only because replacement products have been announced above.
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.
