IIRC, the main problem was that performance was sluggish with XFS over fiber channel, and XFS was not as stable then as (I would hope) it is now, on either system. The main reason they were using SuSE was that Novell came out with version 10.2 with the 2.6.18 kernel about a month or two before CentOS did, and they (DA) already had a SuSE kernel set up with the infiniband drivers they needed for the hardware. FTR, Datallegro does massively parallel processing database appliances, like Teradata, but cheaper, faster and in direct competition with Teradata, which has the name and the history. A 5TB DB is really small for both of them, but it was spread out over numerous nodes within the appliance, so there was no specific file system with anything that large all in one place. HTH mhr
