28 Product Description
Another type of high availability topology connects mirrored disk systems to
redundant hosts. Dual host bus adapters in each host are connected to mirrored
disk systems. With the disk systems in full bus mode (switch 1 on), each host can
reach all disks in both disk systems. If one of the disk systems fails in this
topology, all hosts will still have access to the data on the mirrored disk system.
All connections from the host to the disk system are SCSI LVD cables.
Due to SCSI ID limitations, daisy chaining of the Disk System 2300 is not
supported. The maximum storage capacity with this type of configuration is
approximately one Terabyte. This configuration does not provide any redundant
paths to the data, however there is some hardware redundancy provided by the
disk system hardware (i.e. power supply/fan modules and BCCs). This
configuration can be used for boot, root, swap, or file system storage. Using
Mirror/UX software, one or more mirrors can be created on the same hardware
path to provide a basic level of data protection.
In figures 7 through 11, any BCC shown with only one cable connection should
be understood to have a terminator attached to the other SCSI connector.
