Externally Attached Automated Libraries
Multi-control path architecture
Allows each tape unit in a library access to the robot arm as if it was the
only drive in the library.
Multiple Partitions
The tape library can be split into partitions. Each drive has assigned
cassettes it can use.
Tape pooling
Tape devices can be attached to separate controllers, but the system
software recognizes resources with equal capabilities in a common library
device. At vary on, all equal resources are displayed under the common
library device description. This allows BRMS to assign jobs for a specific
resource to a pool of tapes that are available under this resource.
Available on OS/400 V4R5 or later.
Performance
The actual throughput you may achieve is a function of many components,
such as system processor, disk data rate, data block size, data
compressibility, I/O attachments, and the system or application software
used. The numbers stated here are the maximum throughput attainable by
the tape unit. The best source of information about performance is the
AS/400 Performance Capabilities Reference, SC41-0607, at:
http://publib.boulder.ibm.com/pubs/html/as400/online/chgfrm.htm
As a general rule, it is important to note that SCSI bus technology used by the iSeries runs at
20 or 40 MB/sec. High-end tape drives can attain transfer speeds in the 30 to 45 GB/sec
range, which means the throughput is that of the entire SCSI bus. Even though most tape
drives allow more tape drives connected to the same bus, this is not recommended since you
will never attain full utilization of these drives due to SCSI transfer limitations.
IBM 7329 Model 308 SLR100 Tape Autoloader
The IBM 7329 Model 308 SLR100 Tape Autoloader is a stand-alone
automated tape backup system for use on iSeries servers. It provides media
capacity of 400 GB (800 GB assuming 2:1 compression), automated data
storage at a rate of 5 MB per second (10 Mb per second with 2:1
compression). This data rate is twice the rate of previous ¼-inch tape backup used on the
iSeries.
In addition to reading and writing on new SLR100 50 GB or 5 GB data cartridges, the 7329
Model 308 provides backward write and read compatibility with MLR3 (SLR50) and backward
read compatibility with MLR1 (DC 5010) tape formats. Attachment to the iSeries is via a SCSI
interface adapter.
