We currently run a 2008 Xserve with a Promise e610f RAID and they have both covered us very well so far. However I am starting to think about how to replace them when our luck runs out. This is purely a file-server for five concurrent busy graphics artists and a handful of other users. There are no new Macs that can take a fiber channel card. Is there such a thing as an enterprise-class Thunderbolt RAID? If so, I have yet to find one. My experience with the Promise non-enterprise RAIDs on single stations does not inspire confidence in scaling one up to multiple users. Also, they use poorly-rated consumer-class hard drives and don't officially support much else. Looking down the pipeline, I know that Thunderbolt 3 is coming in the not-too-distant and its friendly USB type-C connector has me hopeful that we will see more TB RAID options. Is that something worth holding out for? And if our equipment doesn't make it that long, what should I be looking at now? Has anybody used the Promise Thunderbolt to fiber channel adapter with success? Thanks for your input!
