We currently have 1Gb/s for our back end server infrastructure, VMware infrastructure, and iSCSI environments. We are pricing out upgrades for our SANs and servers. We've noticed 10Gb/s isn't much more of a price increase. However, we don't have enough 10Gb/s SPF+ module ports available. The switches are costly.
Would you tell me a little bit about the performance increase when you went to 10Gb/s from 1Gb/s for any of the following environments?
VMware (vmotion, management, etc)
SAN (iSCSI over Ethernet) : 40TB over 50 drives
Server - Inter server connectivity for 40+ servers (SQL servers, file servers, web servers, email, and security servers)
