Question HP Z420 and a 14tb internal drive

[crlink27]

hi so i have a HP Z420 workstation according to the HP site the max hdd size is 10tb but that got me thinking if thats a limit set by the oem/storage controller? or by windows I currently am not using it using endeavor OS (arch based linux distro) I was even thinking of RAIDING my 2 drives for a whopping 24tb is it possiable under linux to do this or is the llimit hard coded into the controller itself?

I don't see any indication of max HDD size on here

Is it possible 10tb is the biggest drive size they offer?

I don't think windows has a max hdd space size, beyond what GPT allows now. Meaning 18.8 million TB

I think its set by the controller on motherboard as the Z820 could access more

The Z420 and Z620 support up to 11TB of storage and the Z820 supports up to 14TB of storage.

so it is hard coded can the mem controller be "hacked" to bypass this limit of 11tb?

The 12tb limit appears to be on SATA controller.

the amount of limit seems to be a moving target, they show 12.

I assume you didn't get

Optional SAS controller: LSI 9217 -4i4e 8-port SAS/SATA 6 Gb/s, RAID 0, 1, 10 capable

As I don't see a limit on it - https://docs.broadcom.com/doc/12352067

I don't think you can hack it to give more access, it could be the actual hardware is different. The Z820 has two motherboards in it, as it comes with 512gb of ram.
