Thank you, I ordered a used LSI-9207e (external ports) from eBay for the R710, and the RES2SV240 for my existing ASRock server. Would it be ok to order (2x) SFF-8088 to SFF 8088 (for R710 server) and a dual port 8088 to 8087 PCI bracket (for ASRock server) and (2x) SFF-8087 to SFF-8087 from the dual port to the RES2SV240? It’s more expensive and I don’t know if there will be a speed loss going through the dual port. I think it’ll look nicer and not have to route the cables through the PCI slots. Would it be a faster connection if I just ordered (2x) SFF-8088 to SFF-8087 and route them through the PCI slots to the RES2SV240 directly.

Awesome thank you, time to upgrade my newly acquired R710? How do you calculate max throughput, bandwidth, theoretical speed?

Would adding an expander card slow down the HBA or is there no loss? From your speed test it seems like the LSI 9207-8e and RES2SV240 would be a good combo. Would you recommend something better? I want to get the most speed possible when using (8x) SSD drives.

Oh, seems like I don't know what I'm doing. I was trying to use my existing ASRock server as a storage expansion (DAS i think) to my SFF Dell R710. How would I connect them? Looking to get the highest speed possible. Thank you for your help.

@johnnie.black Great info here. I have a server I built around the ASRock E3C224D4I-14S motherboard that comes with dual (2x) integrated LSI 2308 mini SAS connectors that are connected to (8x) drives. I want to use this server as a DAS box. I have 2x R710 I just acquired, what would be better/faster to connect a R710 to the ASRock server as a DAS? LSI 9207-8e inside of the R710 -> SFF-8088 to SFF-8088 -> SFF-8088 to SFF-8087 PCI bracket adapter -> SFF-8087 to SATA 4x or LSI 9207-8e inside of the R710 -> SFF-8088 to SFF-8088 -> RES2SV240 -> (2x) SFF-8088 to (2x) LSI 2308 -> SFF-8087 to SATA 4x Looking to see what would give me the most speed and/or power consumption. Assuming I use all SSD's.
