Re: HP A5856A support for DS2110
I am not sure that this combination is supported, I would assume so but cannot guarantee. The A5856 is a RAID controller card and you need to setup luns with the irm utility in order to use the storage.
However, the typical config for the DS2100 or DS2110 with an rp5xxx would be to use a single or dual port SCSI card (A6828 or A6829) and use LVM mirroring (MirrorDisk is usually licensed for these servers to mirror the boot disk, so you can mirror without an (expensive) RAID controller.
Since you can have only 4 disks anyway, the perfomance gain of the RAID controller is probably minimal.
If you do *not* have Mirror Disk, just make sure A5858 and DS2110 is a supported combination.

Bernhard

Re: HP A5856A support for DS2110
for A5856A the DS2100 and DS2300 are listed as supported devices, the DS2110 is *not explicitly* listed but as the successor of the DS2100 it *should* be supported.

Bernhard

Re: HP A5856A support for DS2110
if your customer needs HW RAID for perfomance reasons, then you should seriously consider a DS2300 and at least 10 disks or so, then you could use two of the 4 SCSI channels of the A5856 each connected to one half of the DS2300 running in split bus mode.
With a DS21x0 you could use only ONE of the 4 SCSI channels (or you have to buy two DS2110...) since the A5856 does not support multi-initiator configuration (i.e. two channels to the same disks)
