Page: 13 / 94

Chapter 1. General Information
This chapter provides an overview of the IBM
®
TotalStorage
™
IP Storage 200i and
iSCSI clients, and lists the standard and optional features and hardware
specifications for Models 110 and 210.
IBM IP Storage 200i
The IBM TotalStorage IP Storage 200i consists of the IBM 4125 IP Storage Models
110 and 210. These models are designed for workgroups, departments, and
solution providers that have storage area network requirements across
heterogeneous Microsoft
®
Windows NT
®
, Windows
®
2000, and Linux clients (iSCSI
clients). It includes preloaded code and offers virtually “Plug and Play” IP-based
storage.
Model 110 is a tower unit that requires only power and network connections for
setup. A conversion kit is available to convert Model 110 for rack mounting. The
Model 210 can be mounted in a 5U rack drawer. In addition to power and network
interfaces, the Model 210 has external SCSI connections for up to three storage
units for a total rack requirement of 14U.
For additional storage, a Model EXP (also known as a storage unit ) can be
attached to the Model 210 to increase its storage capacity. Each storage unit
supports up to 14 Ultra160 SCSI hard disk drives. It delivers fast, high-volume data
transfer, retrieval, and storage functions across multiple drives.
iSCSI clients
The iSCSI clients allow Microsoft Windows NT, Windows 2000, and Linux
computers to access storage over an IP network. The iSCSI client, as an iSCSI
initiator, issues SCSI commands to the IP Storage 200i according to the
IETF-defined protocol for IP storage.
When the iSCSI client is successfully connected to the IP Storage 200i, any disks
assigned to the iSCSI client appear as a physical disk. Operations normally
performed on a physical SCSI disk can be performed on an iSCSI disk.
Note: You cannot boot from an iSCSI disk; instead, the iSCSI disk is used for
storage after the computer is booted.
You can download the iSCSI client code from the following Web site:
