NX1950 MD3000 SAS
Scratching My head on this, hope someone can help.
June 08, We purchased a NX1950 Box in Basic Congiguration (1 nx1950 and 1 MD3000)
When we bought the box it came with a single SAS HBA. and an additional DUAL network card thus giving the BOX 4 Network Sockets.
Great, we had the network ports we needed plus the HBA SAS 5e.
However when linking it all up we found we needed 2 SAS connections. Complained to Dell who sent us another SAS 5e Card. But the system only has two expansion slots. So the Second network card had to go. One to the LAN for NAS functions and another to the SAN.
This is how it has been operating since then. However i am concerned that we only have 1 network cable to the SAN Thus a major problem should the cable be removed or damaged. As our 2950 ESX server has Dual Network to the SAN router for redundancy, it seems as though this was a major oversight by DELL regarding only 2 port network connections on the NX1950.
Any ideas what i am doing wrong? I thought i bought the right equipment, but Dell are the "Experts" and tell me it is a limitation of the system.
Looking at the deployment guide it says the HBA SAS5/e should have dual connectivity. can some one confirm if this is the case.
Regards Chris
