Secondary data digest used by the volume. Choices are:
No Digest

CRC32C (default)

The longest data segment (in bytes) that the volume can receive. Choices are:
8192

16384

32768 (default)

Primary authentication method used by the volume. Choices are:
CHAP

None (default)

Secondary authentication method used by the volume. Choices are:
CHAP (default)

None

Allows the volume to be set to Read-Only. The available choices are:
Do not set as Read Only (default)

Set as Read Only

Choices are:
Yes (default)

No

Allows you to specify the size of the Read-Ahead data buffer size. Enter this value
as a number of KBytes. The default setting is product of the chunk size and the
stripe width. This setting can significantly affect your data throughput.
Allows the volume caching to be optimized for multi-track audio streams. The
available choices are:
Yes

No (default)

The block size (measured in bytes) that is used by the host operating system to
access the data on the selected volume. Choices are:
512 (default)

4096

The 4096 setting can be used by 32-bit operating systems to access volumes that
are larger than 2TB, up to a maximum of 16TB. However, once an iSCSI session
and connection are established to the volume, this setting will have no effect until
the current iSCSI connection is closed and a new iSCSI connection is opened.
Table 4-3. Advanced Volume Values
Maximum length, in bytes, of the SCSI data payload in a sequence of input (Data-
In) PDUs or solicited output (Data-Out) PDUs. This value is set to 262,144 bytes.
Length of wait time, in seconds, negotiated between the initiator and the target
before trying an explicit/implicit logout or an active task reassignment after an
unexpected connection termination or a connection reset. This value is always 20
seconds.
The level of error recovery that the initiator and the target negotiated. Higher
numbers represent more elaborate recovery schemes. This item is always set to
a value of 0 (session recovery class). For more information, refer to the iSCSI
specification.
Indicates whether the initiator must wait for a R2T request before sending data to
the target. This item is always enabled.
