Looking at the doc
http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00687518/c00687518.pdf
on page 19, HP recommends that battery-backed cache replacement every three years.
besides opening the server, is there any way for me to check whether the cache has been used up?
thanks

Hello Anna, there is no reliable way to tell if the batteries are likely to fail in a short time if the server power fails, hence the 3 year limit. Many users seem to wait untill they get a failure to charge message but by then the cache is offline and performance suffers. I assume you are using the write back option so cache battery is needed. Best to put in new ones if you suspect they are about three years old, then stick a note to the server with the date on for next time, it's an easy 3 minute job and the batteries are quite cheap. Worth it for the peace of mind.
