1.019: (halfway) around the world in (a hundred and) 80 days
Well, it seems that the IBM branded version of the XIV Storage System has arrived - in EMEA, at least:
- IBM Europe Hardware Announcement ZG08-0581
August 12, 2008
- IBM Europe Software Announcement ZP08-0415
August 12, 2008
IBM typically does EMEA announcements first - I'm sure these will appear in the US sites later this afternoon. In fact, TonyP is probably getting his blog post approved by IBM Legal as we speak .
Seriously, it will be interesting to see how the world responds to the pertinent facts about the XIV product, now that it is no longer being shielded from public scrutiny by the cloak of IBM Confidential.

Weird. Nothing from IBM other than the announcement letters posted to IBM.com world-wide. Not even a press release. No customer stories. No insightful spotlight from Tony Pearson. No claims of coming SVC world domination from BarryW.
In fact the only mention of the announcement anywhere else but here and IBM.com is Chris Mellor's coverage of my scoop over on Blocks & Files.
Maybe this whole XIV thing wasn't really all that big a deal after all!
I think I know why...
what's up with xiv?
Here are a few of the more salient points from IBM's announcement materials to help the industry press and analysts get started in their coverage:
- With the XIV Storage System, you can use any type of RAID protection you'd like, so long as you like RAID 1.
- For every 180TB of physical storage you buy in your XIV Storage System, you get to use only 80TB. Not quite sure who buys 100TB more storage than they need in today's economy - even if it IS slow SATA-II storage.
- You can't even install an XIV Storage System smaller than 180TB. Or bigger (yet, at least). One size fits all.
- Even if you choose Capacity on Demand, you'll still be spinning all 180 disk drives 24x7 - definitely not "Green Storage," especially by IBM's standards.
- The XIV Storage System
s' cache memory is apparently run without any protection from bit errors or DRAM failures, making it the only storage system I can think of that doesn't at least mirror cached writes.<corrected Sep 23, 2008>
mirrors write data over a measly 1Gb Ethernet interconnect to a second node
- You can safely replicate your data within synchronous distances only: limited by the speed of light to a reasonable maximum of circa 200 kilometers between your two sites, you'll not be able to protect your data from anything but campus or metro-centered disasters.
- IBM intends to deliver several additional features for the XIV Storage System at some point in the future, including <quote> best practice configuration guidance, change management, asset awareness, capacity utilization, performance trending, operational reporting capabilities, single sign-on capabilities, and to add support for XIV Storage System as a disk system managed by IBM System Storage SAN Volume Controller <end quote>. Sounds just a little like the product isn't quite done yet.
- There is no asynchronous replication being offered for the XIV Storage System. Wasn't even mentioned in the Statement of Direction.
- They seemed to have forgotten to mention any support for non-disruptive tech refreshes and hardware or software upgrades as well. You'd think you'd want to highlight that if you had it, huh?
- No benchmark results have been posted yet, but then, IBM hasn't published any performance claims for the XIV Storage System that I can see either.
I'm sure there'll be lots of fun in the next few days as the emperor struts his new clothes. And of course we'll all be looking forward to seeing TonyP's spin over on Inside System Storage.
Meanwhile, if you'd like to learn more about the realities of XIV, my Stranger Danger post of a few weeks back remains accurate without modification.
