But remember - this is for PERC 5/i and 6/i BBU - not for 5/e or 6/e TBBU !!

I was wondering if anyone with a BBU for perc 5/i could provide me with the specifications for the battery (like a picture).

I’m looking into building my own BBU since new ones are so expensive.

And a quick question if anyone have experience: Does the write-cache get lost if the computer is shut down unexpectedly but the UPS in front still provides it with current? I had an electric spike (thunder) today so the server went down. Dumb as I was I unplugged the server from the Ups and my write-cache was lost resulting in major corruption

Guess you learn from your mistakes

depends on your server really... in the Dell servers where these cards normally exist, so long as the PSU is getting power, it supplies power to the PCI-E bus (even with machine turned off) so that the PERC cards continue to maintain cache. When that goes out, then the battery starts to discharge to maintain the cache ram.

not all servers, especially "home built" ones using desktop computer parts have a system that supplies power to the bus when powered off.

I just tested and its seems that on my motherboard (Asus M4A785TD-V EVO ) the cache is intact as long as the the PSU has power. Just have to remember to never unplug it from the UPS !

I would make sure that it is right before you do anything. Lithium ion batteries can catch on fire EASILY!
Wahoo!

I'm thinking about selling my sig rig and buying a ThinkPad Workstation, but I want to keep my PERC 6i running in a different computer as a media server.
Currently, the PERC RAID resides in my sig rig and I'm thinking of moving it to a P4 Dell rig.
Is it as easy as just moving the card and HDD's to the Dell? Or are there other complications that may come up in the move? I'm going to do a full backup onto a single 2TB drive before the move, just in case.

Thanks in advance!

So I got a Perc 6i and the transfer speeds have jumped dramatically from my (now dead Perc 5i).

Here's a view with 128Kb sector size...

Is there anyone out there that can answer my question?
