Greetings all;
I've just ordered some stuff to rebuild or expand my Raid setup.
This 16 port sata-III pci-e card:
<https://www.amazon.com/dp/B09L184W57?smid=A2H818KAC5I4D1&ref_=chk_typ_imgToDp&th=1>
along with a bigger drive cage, cables and such and some gigastone 2T
drives to make a raid big enough to run amanda. And maybe put a new card
in front of my 2T /home raid10.
The card claims linux compatibility.
Can anyone advise me on the gotcha's of such a 16 port beast?
Thanks all.
Cheers, Gene Heskett.
Searching Amazon for "gigastone 2T", I see:
https://www.amazon.com/Gigastone-Internal-Compatible-Desktop-Laptop/dp/B0BN5978X1
540 MB per second
PCIe 3.0 x1 is rated for 985 MB/s.
https://en.wikipedia.org/wiki/Pcie
So, the PCIe 3.0 x1 connector is going to be a bottleneck when accessing
more than one SSD.
I suggest that you pick an HBA with a wider PCIe connector -- PCIe 3.0
x8 (7.88 GB/s) is a reasonable match for sixteen SSD's (8.64 GB/s).
PCIe 3.0 x16 would eliminate the PCIe bottleneck.
Is everything going into one chassis? Have you considered an external
drive chassis?
Make sure your power supply(s) are adequate to the task.
