There has been a lot of demand lately to boot blade servers using the integrated NICs without the use of iSCSI HBAs.
IBM has partnered with Microsoft to enable this capability for the IBM HS20 (Type 8843) Blades and Netapp has recently announced support for it.
Here are the requirements:
Blade type: HS20 MT8843
HS Blade Baseboard/Management Controller: 1.16
Windows 2003 SP1 w/ KB902113 Hot Fix
Microsoft iSCSI initiator with Intergrated boot support: 2.02
Netapp DataONTAP: >= 7.1.1
Netapp iSCSI Windows Initiator Support Kit 2.2 (available for download from the Netapp NOW site)
One thing to be aware of is that the Microsoft iSCSI initiator version 2.02 with Integrated Boot support is a different binary from the standard Microsoft iSCSI initiator 2.02.
To obtain the MS iSCSI initiator 2.02 with Boot support binary follow the link and provide the following invitation code: ms-8RR8-6k43
