Galaxy GHDX2-2130-16iSCSI Installation and Hardware Reference Manual
iSCSI Topology and Host LUN Mapping:
Configuration Details:
1. A logical drive can be associated with several SCSI IDs on separate channels making
it a RAID volume accessed through different data paths. The default ID on every
host channel is ID#0. More can be created if the need arises.
2. You can manually include or exclude specific iSCSI initiators from the access list to
you iSCSI arrays. A number of access conditioning factors can be included: IQN,
NetMask value, CHAP, and IP addresses can be associated with a RAID array (a
logical drive). In this way, only the authorized host adapters can access your arrays.
3. In the sample below, 2 logical drives are created each out of 8 member drives.
Depending on your demands for logical capacity volumes, specific array parameters
such as optimization modes, spare drives, RAID level, and stripe size/width, can be
specified when creating logical drives.
4. Subnet can be created to reduce overheads and provide access security. LAN
configuration is beyond the scope of this hardware manual.
5. Multiple arrays or multiple partitions can be created and made available separately
through different ID/LUN's on the host ports. The RAID volumes appear as shared
storage over the Ethernet network.
6. To ensure the optimal performance, make sure you connect the iSCSI RAID to a
high speed Gigabit Ethernet network.
