what is the NVME hardware Raid controller for HP Z4 G5 Workstation

[Nilushi5]

need to go with RAID 10 on Z4 G5

[DGroves]

first of all just why do you think you need hardware based raid 10?

second, hardware based raid is no longer recommended, software based raid such a "ZFS" is now used

third, raid 10 is not recommended when using SSD's

forth, the Z4 G5 does not come with a hardware based raid controller, it can however use the Intel "VROC" raid that is a addon optional Key that unlocks this capability in the CPU but it's not cheap!!! and is not true hardware raid it's sort of a software/firmware + minimal hardware raid

SATA Based Raid Options

On-board RAID Support SATA RAID 0 Striped Array
SATA RAID 1 Mirrored Array
SATA RAID 10 Striped/Mirrored
SATA RAID 5 Parity Array

the dual nvme M.2 based slots can be configured as raid 0/1 or raid 5/10 by add ing more nvme drives plus the VROC key

From a previous post (use the forums SEARCH FEATURE)

the intel RSTe raid solution is not a hardware raid controller, it is a "software only" raid driver as such it will not be able to boot (there is a convoluted workaround that is not really pratical)

the HP Z4 G4  does have a M.2 slot plus 2 custom M.2 slots on the motherboard,  these slots  are also software driven raid and like the intel RSTe setup can not normally be made bootable if raiding the drives

the above two methods can be setup as DATA non booting raid configurations, just not as booting raid

the HP service manual does detail raid creation and is well worth reading before posting any further questions here

unlike the earler z8xx series the z4 line does not have a onboard LSI SAS/SATA controller chip / ports

if you need SATA/SAS bootable raid you will have to install a Raid card such as the LSI 9270-8i which can be found on ebay new as a white box item for under 200.00
