这个要求我觉得iSCSI跑1G应该可以应付了, 如果未来网速不够快upgrade 到10G也是很容易的事
1G/10G switch比FC switch 要便宜很多, 而且配置简单
This is what they try to convince us. what do you think?
Basically if we want to go virtual, all data, virtual servers images and backups would be placed on SAN (Shared storage).
In iSCSI case, the SAN is connected with 1 GB link to the rest of the infrastructure. This link could be a potential bottle neck if we would virtualises resources hungry servers including Exchange and SQL.
This is because of all data including system files, virtual images, user files, backup to disk-to-tape would have to cross that 1 GB link to the SAN.
FC has a throughput of 4 GB and would remove that bottle neck. |
