Smart Array B120i SSD TRIM

[Justin Hindle]

Hi,

Could anyone advise how or if the Smart Array B120i in a HP Gen8 Microserver handles TRIM with SSD hard drives in general or in a mirror?

Thanks

Hi,

Some where I read that HP SSD do not have TRIM command and instead they use "over-provisioning" and "wear leveling" techniques.

Refer to page#5 in the below document.

As far as I understand, TRIM must be supported by Smart Array firmware and SSD firmware.

Hi Suman_1978

Thanks for the indepth reply, I'll finish what I'm working on and do some reading!!!

Do you know if your reply applies to non-HP SSDs it Intel SSDs?

Thanks

Hi,

My reply was about HP SSD but in case of Intel SSD, even then the command has to go through HP Array Controller, so I guess it will not work.

You can try at your choice.
