To boot or not to boot from a SAN: That is the question You’ll need to decide whether or not you want to boot ESX from a SAN before you install the server. ) You can boot from SAN with both Fibre Channel and iSCSI (each have a section in this chapter). The only iSCSI catch is that you need to use a hardware initiator instead of a software initiator (covered later in this chapter in the section on iSCSI). No matter how you boot your system, you will likely be using the SCSI command model. The only difference in your SAN options is how the commands reach your disks.
Dual, virtual CPU machines force co-scheduling of physical processors. With co-scheduling, if one physical processor is scheduled, a second one is as well. This can take resources away from your other virtual machines. Additionally, if Process 1 on virtual CPU1 is waiting too long for Process 2 on virtual CPU2 to finish, both processes might get scheduled out (finish their allotted share of CPU time and lose the processor until their next turn) before completion. This can negate the benefits of using multiple CPUs.
