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?
Got one of those coming too. Small possibility it will fit it the bottom
of this huge and old tiger direct tower. Because the radiator for the 6
core i5 is too tall, it hasn't had a side cover on it in years. If not,
theres a 3 3.5" cage at the bottom of the stack I can stuff with 2
SSD's per bay slot. A hidey place, front cover is solid, but cooling
might be a problem. If worse comes to worse I could shoe-goo a 120x15 to
the side of the cage.
Make sure your power supply(s) are adequate to the task.
400 watter, presently runs dead cold. 5V line rated at 16A, probably not
using half that now.
