Data path redundancy can be secured with the configuration shown in Figure 9. Using an additional host bus adapter (HBA) and the LVM software, alternate links can be created, providing a redundant path to data for each disk system. In addition, a separate mirror path can be created for data protection. This configuration provides protection against any single component failure (i.e., cables, HBAs, disks). Figure 9 depicts connecting two disk systems to a single host. The only limit on the number of disk systems per system is the maximum number of supported HBAs. For large configuration, it is recommended that multiple CPUs have large amounts of memory to handle the system load. Each disk system in this configuration is capable of 160MB/s performance. Due to SCSI ID limitations, a maximum of 13 disks is supported per disk system (13 disks + 2 HBAs + 1 SES = 16 SCSI IDs). 30 Product Description

Product Description
Data path redundancy can be secured with the configuration shown in Figure 9.
Using an additional host bus adapter (HBA) and the LVM software, alternate
links can be created, providing a redundant path to data for each disk system. In
addition, a separate mirror path can be created for data protection. This
configuration provides protection against any single component failure (i.e.,
cables, HBAs, disks). Figure 9 depicts connecting two disk systems to a single
host.
The only limit on the number of disk systems per system is the maximum number
of supported HBAs. For large configuration, it is recommended that multiple
CPUs have large amounts of memory to handle the system load. Each disk
system in this configuration is capable of 160MB/s performance. Due to SCSI ID
limitations, a maximum of 13 disks is supported per disk system (13 disks + 2
HBAs + 1 SES = 16 SCSI IDs).
