I am doing a small project with Computer Recycling to sort through a<br>
large number of drive arrays they have received. I am running into<br>
trouble because we are missing cables and controller cards for some of<br>
this hardware. I am wondering whether any of you have spares (or old<br>
stuff) around that I could borrow for a while (or maybe that we could<br>
purchase). We have thought about purchasing cables ourselves, but<br>
cables are not cheap, and we don't know whether this equipment is any<br>
good.<br>
<br>
<br>
<br>
I am not super-familiar with this world so I am probably saying stupid<br>
things. Please forgive me and correct my misunderstandings. <br>
<br>
I am taking descriptions of ports here: <br>
<a href="https://en.wikipedia.org/wiki/Serial_Attached_SCSI#Connectors" rel="noreferrer" target="_blank">https://en.wikipedia.org/wiki/Serial_Attached_SCSI#Connectors</a><br>
<br>
I have an IBM SR-BR10i (maybe a rebranded LSI SAS 3082E-R) RAID<br>
controller card which might work for testing the drive arrays. It has<br>
two ports which I think take in SFF-8087 connectors. I do not know<br>
for certain whether this card works and I do not know whether it is<br>
sufficient to connect and test these drive arrays.<br>
<br>
<br>
<br>
I have a Dell MD 1000 that I think takes in an SFF-8470 connector (the<br>
Infiniband one from the Wikipedia page), but I do not have any cable<br>
with that end.<br>
<br>
<br>
<br>
<br>
I have some IBM drive arrays that I am hoping to test. Most of them are<br>
IBM exn3000 (alternatively: 2857-NAS) that I believe have QSFP ports. <br>
We have some QSFP cables and I have one that I believe is SFF-8088 to<br>
QSFP. But I do not think I can connect a SFF-8087 to a QSFP directly,<br>
so I need an adaptor? I am not sure how this works. I do have one IBM<br>
server that I have used to successfully detect the drive arrays, but<br>
that is about as far as I can go, because the built-in RAID controller<br>
is not well-supported by Linux any more. <br>
<br>
There are not good pictures of QSFP connectors, but here is the<br>
wikipedia page: <a href="https://en.wikipedia.org/wiki/QSFP" rel="noreferrer" target="_blank">https://en.wikipedia.org/wiki/QSFP</a><br>
<br>
<br>
<br>
<br>
<br>
We also have some oldish IBM drive arrays that have Fibrechannel<br>
connectors. I have no idea whether I can make these work, or what I<br>
would need to do so (I think I need big expensive proprietary IBM<br>
controller that I cannot use without expensive proprietary software I<br>
don't have). Maybe I can access those drives directly? They have<br>
connectors that look like this: <br>
<br>

<br>
In particular, here is somebody selling one of the models in the array<br>
for some money: <br>

<br>
<br>
<br>
<br>
Anyways, if you have some of the cables/adaptors/cards/etc that I<br>
would need to test this equipment then please get in touch. If you<br>
know in particular what I should be looking to get in order to test it<br>
that would be helpful too. Our goal is to evaluate some of this stuff<br>
for internal use, but if for some reason you want to purchase it from<br>
Computer Recycling (especially the Fibrechannel stuff) then we may be<br>
able to make arrangements. In the worst case we will give up, strip<br>
what we can and then e-waste the rest.<br>
