2.4.3 RS/6000 Model E20 Limitations
When planning or implementing an RS/6000 Model E20, give special consideration
to the following limitations, which are also listed in the announcement letter for this
product.
Internal Disk Drives
Only internal disk drives with a 1-inch height (half-height) are supported. Disk
drives with 1.6-inch height (4.5 GB disks) are not supported. Installation of any
full-height internal disk may result in overheating the system, and data consistency
is not guaranteed
Internal Tape Drives
The 4 GB/8 GB 4mm internal tape drive may be mounted in bay number 8 only.
This insures adequate air flow, as required for proper operation. A second tape
drive may be installed in bay number 6 if bay number 7 remains empty. Mounting
in another bay may cause overheating and lead to data errors.
No 8mm internal tape drive can be installed in the RS/6000 Model E20.
Graphics Adapter
There can be a maximum of one graphics adapter installed on the system.
SCSI Adapters
The limitations regarding SCSI adapters and the number of attachable devices are
shown in Table 6 on page 26.
2.5 RS/6000 Model F30 Product Description
The RS/6000 Model F30 significantly enhances the IBM PCI-based RS/6000 family
of entry servers. The Model F30 is a workgroup server that is well suited for the
emerging markets of distributed computing and interoperability. Like the RS/6000
Model E20, the F30 can be used with existing AIX 4.1.4 applications where industry
common PCI and ISA standards are required.
The Model 7025-F30 is a powerful and expandable server designed to combine the
following attributes:
Outstanding performance of PowerPC technology - 820 estimated transactions
per minute (tpm)
System expandability supporting 10 I/O slots and 22 media/disk bays.
Reliability characteristics of commercial servers
Industry common I/O and memory architectures
Packaging characteristics of small departmental servers
It offers more performance, more I/O slots and more bays than the Model E20 as
well as offering enhanced server RAS characteristics, such as ECC memory.
The F30 is packaged in a 10 x 22 (10 I/O slots, 22 media/disk bays) floor-standing
tower which is attractive, compact and quiet. It includes a modular disk subsystem
