XOR Control Mode page (10h)
The XOR Control Mode page provides the initiator with the means to obtain or modify certain XOR target oper-
ating parameters.
Field definitions (listed alphabetically)
Maximum Rebuild Read Size
The maximum rebuild length (in blocks) that the target will use for Read commands during a rebuild operation. This field
does not limit the rebuild size.
Maximum Regenerate Size
The maximum regenerate length (in blocks) that the target accepts for the Regenerate command.
Maximum XOR Write Size
The maximum transfer length (in blocks) that the target accepts for a single XDWrite Extended, XDWrite, or XPWrite com-
mand.

XOR Control Mode page code.
Page Length
16h
The length of the XOR Control Mode page (in bytes). If the allocation length is too small to transfer all of the page,
the page length is not adjusted to reflect the truncation.
