Dell PERC H755 compatibility

[rickylai]

I am planning to buy a new Dell R750 Server for my TrueNAS Server. The dell server comes with Dell PERC H755 SAS Raid Card.

I heard that Raid Card should be avoided for TrueNAS. But the H755 comes with HBA (non-raid) mode.

So is it ok to use the H755 has controller card?

Thanks!

No, of course not. It's still a RAID card. Get rid of it and use a true HBA.

What's all the noise about HBAs, and why can't I use a RAID controller?

1) An HBA is a Host Bus Adapter. This is a controller that allows SAS and SATA devices to be attached to, and communicate directly with, a server. RAID controllers typically aggregate several disks into a Virtual Disk abstraction of some sort...
