Hello,
Yes it is possible. If this is FC-SAN then you will want to make sure your ESX Fixed/MRU settings are set properly. In general you want it set to fixed in a multi-SAN configuration. You can also use multiple iSCSI Servers from different vendors with no major issues. You may want a more robust storage network in use however. 1GB may not be enough for everything. But that depends more on what you are doing than what iSCSI Servers are in place. It is a bandwidth issue.
