Understand the use cases and limitations when using an iSCSI LUN as a boot device for a VMware ESXi host.
- [Instructor] In this video I'll explain how ESXi hosts…can boot from a LUN at an iSCSI storage array.…Booting from iSCSI supports hosts with no local storage,…and this can be really useful in high density…blade server architectures.…In a blade chassis, it's desirable…to generate minimal heat, for example,…and spinning discs generate heat.…So if we can install blade servers that have no local…hard drives in them, this'll give us the capability…to have more compute resources in a smaller physical space.…
Boot from SAN is possible on dependent…hardware iSCSI initiators that support this feature.…And this really varies from vendor to vendor.…Bear in mind, with the dependent hardware iSCSI initiator,…we're still going to require a VMkernel port.…It's also supported on independent…hardware iSCSI initiators, and software iSCSI initiators…that support the iSCSI Boot Firmware Table,…or iBFT format.…
So let's assume we're using a dependent hardware…iSCSI initiator.…The first step in configuring boot from SAN…is to configure the physical adapter,…
