Maximum memory for HP Dual M.2 to PCIE SSD Adapter Kit in a dual Xeon Z8 G4

[drpalmer]

I recently purchased two: HP Dual M.2 to PCIE SSD Adapter Kit For Z8 G4 Worstation 844779-001 L32771-001 on Ebay for a newly purchased Z8 G4 and Z6 G4.

For the life of me, I cannot find the maximum size of the m2 card that is supported nor can I find the spec sheet.

I would like to know the maximum amount of memory I can install in each adapter that will be recognized by the Z6 and the Z8.

Any help is appreciated.

the HP dual M.2 SSD card could care less about the ssd capacity,..... that's a limitation of the system the card is installed in and newer systems like the Z8/z6 will accept ssd sizes greater than what's currently available to buy

Drpalmer,

This specification sheet for the HP Dual and Quad Turbo Pro's:

https://www8.hp.com/h20195/v2/GetPDF.aspx/c04798669.pdf

> shows a maximum of 2TB drives.

However so far I've been unable to find any capacity limitation listed for the HP 844779-001 which, anyway, appears to be of a different design than the adapters listed above.  As each M.2 drive will consume x4 PCIe lanes regardless of capacity, it should accommodate any capacity. 

Given the cost of these drives, and the vagaries of proprietary adapters (special firmware?) consider verifying with the seller in advance that a drive may be returned if it is incompatible with the adapter.

For reference, the highest Passmark Performance Test Disk score for an HP Z8 G4 is 28287 using a Samsung 970 EVO Plus 2TB. the second highest mark = 28170, also a Samsung 970 EVO Plus 2TB

For the HP Z6 G4  the top mark is:  Disk = 24859  using Samsung 970 PRO 512GB and second is Samsung 970 EVO 2TB @ 23324.
