I learned, to my chagrin, a few years ago that the HP xw8600 workstation I was running is limited to 2TB disks. Of course, I'd already gotten two 3TB disks. Needless to say that taught me to check in advance from then on.
I'm now running an HP Z800 and would like to gear up to running 8TB hdds, in 2 mirrored pairs on zfs.
Can anyone tell me if I am likely to run into any limitations in the Z800 at that size of HDD?
The host in question has dual Xeon Cpu: Version: Intel(R) Xeon(R) CPU X5675 @ 3.07GHz.

the z800 's sata controller is limited to approx. 3.82 TB (actual capacity) for a boot drive if using the latest bios some advertised 4tb drives are actually under 4TB and as such will work,............... non bootable drives up to 6TB are known to work also larger may work but i have no personal knowledge on them
here's a 4TB drive that is under the z800's bios limitation

the same goes for the z800's onboard LSI controller, i personally would install a adaptec 6805/71605 card, which will boot large capacity SAS or SATA drives, (disable the onboard LSI) supports raid or JBOD, and is SATA III 6GBps capable i have used both, and for the z800 the 6805 is the best bang for the buck but the 71605 is more future proof
i uses 4 male to male sas/sata adapters which allowed the card to control the 4 internal hotswap bays in the z88/z820 systems and then power 4 SSD's
