I have bought a few of these single port devices to put in each ESXi box I own: Mellanox Connectx-2 MNPA19-XTR. I recently spotted a deal on a Mellanox Connectx-2 MHQH29C-XTR which is a dual port and I will put in the main ESXi box.
Now I'm looking at different scenarios but both have its pros and cons:
This is my first experimentation for 10GBE/Infiniband. I need 10GBE for NFS/iSCSI for ESXi as well as running backups for ZFS file systems.
My main concern is: which cables should I buy? Should I get QSFP+ to 4xSFP+ breakout cables? Does Mellanox lock out their cables so you need to buy their brand or you can buy anyone you want?
Thank you very much in advance.
Now I'm looking at different scenarios but both have its pros and cons:
- Use the "main" ESXi box as a switch for 10GBE where all other SFP+ modules connect to. Run 10GBE Ethernet on it.
- Buy an infiniband switch then every device connects to the infiniband switch. Run infiniband on it.
