2105 Versatile Storage Server - IBM i series Handbook

2105 Enterprise and Versatile Storage Servers
There are two adapters available to attach the ESS to an iSeries server – SCSI and fiber:
• SCSI attachment is supported using a #6501 (SPD) adapter. In this configuration, the
ESS emulates a 9337-5xx drive, based on the size of the disk unit installed. OS/400
V3R1 supports 4 GB and 8 GB LUNs and V4R2 supports 4 GB, 8 GB, 17 GB, and 36
GB LUNs.
Sixteen disk drives (LUNs) are supported per #6501, with up to a maximum of 16 #6501s
for 32 ports on the ESS.
• Models F10 and F20 attach to iSeries 270 and 8xx servers using the #2766 Fibre
Channel DASD Controller with OS/400 V5R1. Each #2766 supports 32 LUNs. A LUN
can be 8.58 GB, 17.54 GB, 35.16 GB, 36.00 GB, or 70.56 GB.
Fibre attachment is either directly to the ESS (point-to-point) or via a 3435-1RU Fibre
Channel Managed Hub using Fibre Channel Arbitrated Loop (FC-AL) connectivity.
Switches are not supported. However, the 2109 SAN Fibre Channel Switch Models S08
and S16 can be used in QuickLoop mode to attach iSeries to the ESS.
Up to five iSeries servers can be on a single loop. Performance considerations apply.

Disk and Tape with iSeries , SG24-6220, available at:
Note: Prior to ordering the #2766 Fibre Channel Disk Controller, read and understand the
no-charge RPQ 847126 - iSeries Fibre Channel Adapter for Enterprise Storage Server.
RPQ 847126 must be ordered for the #2766 to ship with the system. Configuration and
installation considerations are discussed in the documentation shipped with the RPQ.

2105 Versatile Storage Server

The IBM 2105 Versatile Storage Server (VSS) is designed to provide a flexible approach to
storage centralization in support of server consolidation. By using the IBM 7133 Serial Disk
Subsystem as its storage building block, VSS provides investment protection for customers in
a heterogeneous processing environment. With the IBM VSS, disk storage can be
consolidated into a single, powerful system to offer many levels of advanced function.
Examples include remote Web-based management, true data sharing for like servers, and
dynamic capacity allocation.
The Versatile Storage Server supports 7133 Models 010 and 020 and the D40 Serial Disk
Subsystem containing 4.5 GB, 9.1 GB, and 18.2 GB disk drives. Disk units are grouped in
similar groups of four or eight. The drives emulate the 9337 Model 580 or 590 respectively.
The VSS attaches to the iSeries server using the #6501 Tape/Disk Device Controller. The
