Competing against Pillar at an account. One of the things they said: That their RAID5 is superior in reliability to RAID6. I wanted to put this on the public domain and, if true, invite Pillar engineers to comment here and explain how it works for all to see. If untrue, again I invite the Pillar engineers to comment and explain why it’s untrue.
Much has already been written about this imminent acquisition of Data Domain by either NetApp or EMC and, since opinions are like you-know-what, and I have one, here it isâ€¦ if I ramble, forgive me. I have too much to say and Iâ€™m trying to be PCâ€¦ I wrote and subsequently erased all kinds of stuff that could probably get me in trouble (the more you work with a company the more dirt you uncover, and I have several earth moversâ€™ worth).
I just got this information:
For XIV to be in jeopardy you need to lose 1 drive from one of the host-facing ingest nodes AND 1 drive from the normal data nodes within a few minutes (so there’s no time to rebuild) while writing to the thing.
Have no way of confirming this but it did come from a reliable source.
A customer recently tried pulling random drives and XIV didn’t shut down and was working fine, but they were from the data nodes.
Why can’t anyone post something concrete here? I’m sure IBM won’t post since the confusion serves them well.
For what it’s worth, the customer is really happy with the simplicity of the XIV GUI.
By now most people dealing with storage know that IBM acquired the XIV technology. What IBM is doing now is trying to push the technology to everyone and their dog, for reasons we’ll get into…
So I’m now the proud owner of a tricked-out 2.8GHz MBP.
Naturally I’ve been tinkering with it already (only had it for 2 days). I’ve disabled swapfile encryption, for instance, and I think it makes it have teh snappy.
