Hi,
I'm fairly familiar with the 3ware range of SATA RAID controllers
and their particular quirks. I'm finding them harder to get hold of
however, and I've now repeatedly run into the situation where my
suppliers are pushing LSI MegaRAID instead.
Have any of you transitioned from 3Ware to LSI and how have you
found it?
Particularly the 9260CV controller is being suggested to me instead
of the 3ware 9250SE-8LP. This appears to have a large capacitor
instead of a Li-Ion battery in order to achieve its battery backup.
Anyone got any experience with that?
Cheers,
Andy
It works. It has both a capacitor and flash memory, the idea being
that you won't have battery maintenance. The capacitor has enough
juice to dump the RAM cache to flash during an outage and is far more
heat resistant and more stable as far as reliably holding a charge.
Adaptec has been doing it longer with their Zero Maintenance flash
modules, I believe they introduced the technology to the market, but
at the moment LSI has the performance lead if you're using hardware
RAID. That might change in a month or two when Adaptec's quad-core 7
series comes out.
LSI's MegaCli utility is a pain to work with compared to twcli, but
I've been told that they are on the verge of releasing a better
'megaware' cli that mimics twcli and is thus more user friendly.
