2105 Enterprise and Versatile Storage Servers
Centralized management is simplified by using IBM StorWatch. Versatile Storage Specialist
(part of StorWatch) is a Web-enabled, integrated storage management tool. Versatile Storage
Specialist enables local or remote storage administrators to monitor and manage the
Versatile Storage Server using a Java-compliant Internet browser. This enables growing
volumes of data to be managed more cost effectively than ever before.
Based on the IBM Seascape storage enterprise architecture, Versatile Storage Server
combines technology building blocks, including powerful storage servers, rich software
function, high-performance adapters, and serial disk technology. Seascape solutions take
advantage of technological advancements in various components without making entire
systems obsolete, which protects existing storage investments. Versatile Storage Server is
designed to grow with your organization. You can add capacity, terabytes of usable storage,
as you need it. Mixed capacity hard disk drives are supported concurrently and Versatile
Storage Server is designed to allow additional capacities and new generation serial disks to
be easily incorporated.
Data center operations are enhanced by the many advanced features designed to protect
data and deliver high availability, even in the event of a failure. Dual active processing
clusters with automatic failover, hot spares, hot swappable disk drives, and redundant power
and cooling provide high availability. Data protection and integrity are provided by a
high-performance RAID-5 implementation that includes mirrored, nonvolatile fast-write cache.
The IBM Versatile Storage Server provides further protection by verifying data accuracy at
every operational step, even down to the disk level. This is an important safeguard for
environments such as e-business.
The Versatile Storage Server supports 7133 Models 010 and 020 and D40 Serial Disk
Subsystem containing 4.5 GB, 9.1 GB, and 18.2 GB disk drives. When attached to the
AS/400 system, disk units must be grouped by four like units or eight like units. These groups
of drives then emulate the 9337 Model 580 for the 4.5 GB (4.1 GB usable) disk units or 9337
Model 590 for the 9.1 GB (8.5 GB usable) disk units. No other disk units can be emulated.
The Versatile Storage Server is attached to the AS/400 system using the #6501 Tape/Disk
Device Controller. Due to the capabilities of the VSS for a maximum of 16 SCSI Interfaces
and the #6501, when the Versatile Storage Server is attached to the AS/400 system, the
maximum capacity is 536.3 GB when using the 4.5 GB Disk Units and 1099.5 GB when using
the 9.1 GB Disk Units.
IBM 7133 Model 10 and Model 20 are for migration only. They are withdrawn from marketing.
