Section 14.5. Faultless Fault Tolerance


14.5. Faultless Fault Tolerance

With each release of ESX Server, support for clustered virtual servers has increased. We imagine this trend will continue with the next release. A recently published paper form VMware examines the possibilities of geographically dispersed clusters (see Chapter 4) utilizing EMC hardware and software. VMware in the past tried to show nearly equal support between the SAN manufacturers, so you can bet that new and interesting fault-tolerant solutions will become available, ensuring a greater degree of uptime and service availability. Support for iSCSI, of course, would create interesting possibilities, and in a report featuring EMC on iSCSI, EMC said that it "estimates cost differentials between iSCSI and FC (Fiber Channel) to be between 18 percent and 40 percent depending on the hardware used and number of servers connected."A cost-effective transport for storage supported by VMware would definitely open up more possibilities for virtual infrastructures.
