disk write cache

[steven_elvisda]

Dear All,

I would like to ask you for your experience that

I just purchase server from ovh.

after install the cPanel and cloudlinux I check on the Server Status -> Server Information at Physical Disk

I found
Write cache: disabled, read cache: enabled, doesnt support DPO or FUA

is it mean Write cache of hard disk disabled.

do you have any idea? please kindly share.

everyone thanks that because of cloud linux? base on the answer from OVH they said because of Im installed OS and need to turn it on OS.

what do you think about this?

can you share your idea?

I wouldnt recommend turning on write caching unless your server is protected by a UPS and/or redundant power supplies.
