个人的观点:
1-iscsi走的是标准的TCP/IP协议,没特殊要求
2-V5和V4的最大区别,在ISCSI这块,就是对于IP SAN的必须要求是1GB的速度,你可以去查手册;为什么4可以挂成功,而5失败,应该是ESXI的主机在这里认为你的IP SAN网络不符合最低要求(1GB);还有管理网络,也是要求1GB的;
在DELL的IP SAN (MD3200I)的最佳实践手册上也有句话:(必须超5类或者6类线材)
General Network Practices: Make sure the category rating for the cables used are gigabit Ethernet compliant (CAT5e, CAT6). Design your network to have the least amount of hops between the array(s) and the host(s). This will greatly reduce your failure points, simplify your manageability, and reduce latency and complexity of your network architecture (particularly in the area of redundancy). Managed switches are recommended because they provide advanced features to help you optimize and maintain your network for your application. It is recommend you use auto-negotiation only, since gigabit Ethernet networks are designed to always have auto-negotiation enabled. If a particular application requires a specific speed/duplex mode, this must be done by changing the advertisement options of the switch.
