Having done a quick run through of the Xsan mini-site, I can't help but admit to feeling a little twinge of excitement.
Consider the following:-
- A maximum volume size of 16TB, but no mention on how many volumes. Even if the limit were relatively low (16?), you could have a SAN of 256TB.
- The ability to 'stripe' data across multiple Xserve RAID units: in other words, one RAID unit goes down, who cares?
- HSM capability through a pre-defined relationship with ADIC (who are currently my flavour du jour for tape libraries)
Now, I've just done a quick shopping list and 42TB of fully tricked-out storage costs around $200,000 including two 16 port FC-SW switches and two (well-specced dual-processor Xserve) Xsan metadata controllers.
I challenge anyone to go and beat that by a factor of two or three. I know how much that costs to implement as an IBM Faststor product, and it's horrific.
If Apple can't use this to prise the enterprise open again, then something is wrong, either with their salespeople or the enterprise buyers.
