* If the controller is unable to obtain a DHCP address on a given network port, it reverts to a default IP address, which may take up to 3 minutes. The default IP addresses are as follows:

• disk pool: A set of drives that is logically grouped. A disk pool provides the overall capacity needed to create one or more volumes. A disk pool is similar to a volume group, with the following differences. The data in a disk pool is stored randomly on all of the drives in the disk pool, unlike data in avolume group which is stored on the same set of drives. You do not specify a RAID level for a disk pool. A disk pool does not use hot spare drives. A disk pool allows a large number of drives to be grouped.
• volume groupA set of drives that is logically grouped and assigned a RAID level. Each volume group created provides the overall capacity needed to create one or more volumes.

Disk pool benefits

    Easy to Create – It is easy to create a disk pool in the storage management software. To create a disk pool, simply select the drives from a list of eligible drive candidates. After a disk pool is created, you create volumes.
    Better Utilization of Drives – When new drives are added to an existing disk pool, the storage management software automatically redistributes the data across the new capacity, which now includes the new drives that you added. The data in the volumes remain accessible when you add the drives to the disk pool. When you delete disk pool volumes, the capacity of those volumes is added to the total usable capacity of the disk pool and, therefore, can be reused.
    Note: You have the option to manually create a disk pool, if you prefer not to proceed with the automatic disk pool creation process.
    Improved Reconstruction Experience – Disk pools do not use hot spare drives for data protection like a volume group does. Instead, spare capacity is allocated within each drive that comprises the disk pool, thus distributing the reconstruction workload. This means that reconstruction of failed drives completes faster and has less impact on performance than traditional volume group reconstruction.

Controller 1 (port 1): IP Address: 192.168.128.101

Controller 1 (port 2): IP Address: 192.168.129.101

A spare drive that contains no data and that acts as a standby in case a drive fails in a Redundant Array of Independent Disks (RAID) Level 1, RAID Level 3, RAID Level 5, or RAID Level 6 volume. The hot spare drive can replace the failed drive in the volume. Hot spare drives are used only in volume groups, not disk pools.
