RE: iSCSI Boot Process Draft

["Prasenjit Sarkar" <psarkar@almaden.ibm.com>]

Hi Doug,

If I understand your question correctly, can the file field be shared by
TFTP and iSCSI?
Absolutely - based on a client identifier specified in the bootp draft(s),
the bootp server
can choose to return either a tftp "file" entry or an iscsi "file" entry.
In other words,
TFTP and iSCSI booting can co-exist in the same environment.

The draft is moving towards dhcp options, so that the configuration can be
done
by dhcp servers without field sharing.

There are a lot of boot protocols other than the ones discussed above -
system
manufacturers have a lot of choice in this matter. Should they decide to
boot off iscsi targets, the boot draft will be relevant.

Prasenjit,

Is it your opinion that iSCSI replaces TFTP as the means of obtaining boot
sectors and system manufactures must adopt iSCSI within their networking
boot code?
