SolutionAfter the disks, I'll guess that the next most common thing to fail is the cache batteries.
Going back to the original question, were you referring to the loop switches in the EVA5000 or the the SAN switches to which the EVA and the hosts are connected ?
Cheers,
Rob

Re: EVA5000 FC Switch Life
If you have experience with both then it would be great to know how long each of the lasts. I have a rather old EVA 5000 that I am in charge of and just wanted to prepare myself :-) Our EVA is at least 6 years and I think it was purchased used then! Thank you!

Re: EVA5000 FC Switch Life
I don't think I've seen either fail to be honest... I've had the odd PSU fail on a HP (rebadged Brocade) SAN switch, but most have dual power, so no great problems there.
I don't recall ever seeing an issue on any loop switches, except perhaps a flakey GBIC/SFP. On early EVA5000s you had fibre connections between the switches and the disk shelves. Later models have copper cables with "built in" SFPs which are less prone to breaking.
Hope this helps,
Regards,
Rob

Re: EVA5000 FC Switch Life
I can report some failed disks and cache batteries. After that some SFPs, but most hostports SFPs. No failed controllers or loop switches.
Best regards,
Patrick

Re: EVA5000 FC Switch Life
Unfortunately, all back-end switches I've seen so far do not have redundant power supplies :-(
And I also had some discussions with Brocade who do not put redundant power supplies in some front-end switches. The argument is that a power supply does not fail that often -- to which I respond that power lines go down more often (true failure or maintenance reasons) than power supplies fail.
The difference between theory and practice...
