iSCSI Storage

Blade chassis with 3 blades, each with power-chewing, potential-for-

failure hard disks.

iSCSI storage installed on

network.

Boot volumes carved out of iSCSI storage and assigned

client (initiator) names, matching corresponding

blades’ iSCSI initiator name.

Microsoft iSCSI-boot-capable initiator +

winBoot/i client tools installed on blades.

winBoot/i server software installed.

Blades’ network adapters are assigned to iSCSI boot volumes.

Hard disks’ boot volumes copied to iSCSI storage.

winBoot/i clients are now ready for iSCSI boot, using one of:

• emBoot PXE bootstrap

• emBoot OptionROM on NIC

• emBoot OptionROM embedded in BIOS

Local disks can now be removed, or kept for

paging or other swapping tasks.

Blades are started, and receive boot instructions from winBoot/i management.

Boot volumes

iSCSI storage delivers OS+applications+data to winBoot/i clients (blades)
