The iSCSI solution is Ethernet based. How can this be better than the HSL that IXA uses?
An IXA can only use a portion of the bandwidth provided by HSL. All of the devices in the HSL loop, including other IXAs or I/O Towers, share the bandwidth available. In addition, the IXA uses hardware to attach to the HSL loop that has bandwidth constraints smaller than the total bandwidth available in the HSL loop. In contrast, iSCSI provides 1 Gbps full duplex connections that are used only by integrated servers.
