Hi everyone!

Can someone tell me what 375-0087 is? What does it cache?

Thanks,

things will be lost in time, like the root partition last week.

It's a Prestoserve card, which is battery backed up RAM, and it caches NFS
transfers. Most RAID arrays these days have non volatile RAM caches in
them, making this rather redundant, but it's a nifty piece of hardware all
the same.

Thank you for your explanation.

Would this work on an SS20 with Solrais 9?

Aye, it will indeed.

You'll need to find drivers for it (I think the latest ones were for
solaris 8, but it does work with solaris 9 and the solaris 8 drivers.)

be shure to remove the battery jumper if it has one for 5 min.
before installing otherwise you risk flushing nfs data
from the old system it came from to the new.

And -- make sure that the batteries (soldered in place) are
still good before depending on it. Worst are marginal batteries, which
let some data get corrupted while it looks to the drives as though it is
still preserving data.

As for jumpers -- mine have a four position dip switch with a
single actuator, to maximize the current carrying capability when it is
switched on.

Enjoy,
