1 Broadcom® iSCSI Boot Functionality

1.1.1 Background and Overall Benefits:
One of the recent storage technologies to rise within the datacenter is iSCSI boot functionality. iSCSI boot is a process whereby the operating system is initialized from a remote storage disk array across a storage area network (SAN) rather than from the locally attached hard disk drive. Thefunctionality reduces the datacenter’s total cost of ownership by contributing to lower power consumption, better solution performance, localized patch management and real estate cost savings. Enabling SAN-like benefits at attractive costs, this diskless booting option is now available through the omnipresent and ubiquitous low cost Ethernet fabric via Broadcom’s leading-edge converged network interfacecontroller (C-NIC) technology first introduced in 2004.

A key benefit of iSCSI boot is that it localizes hard disk drive errors and contains them. With iSCSI boot functionality, the operating system is booted from the SAN and the local hard disk drives will then be recommended for SWAP files and crash dumps. This provides, tremendous benefits to blade servers and virtualization computing serverenvironments relating to RAID management and consolidated external storage.

As disk storage space for mobile and thin clients has increased via remote access to these dedicated storage spaces, iSCSI boot functionality provides an avenue and a giant step beyond conventional boot options such as PXE, BOOTP and RPL, enabling better security, storage and patch management being a standards-based solution.1.1.2 Implementation:
In implementing iSCSI boot functionality, it is typically loaded on the initiator (and represents the diskless client). The physical hard drive is removed from the client system and resides on an iSCSI target.
