High-performance design further enhanced

by turbo option

To meet growing needs for storage

capacity and performance, the DS4300

Express may be upgraded with the

turbo option, which includes DS4000

Storage Manager version 9.10 (the

base dual controller model includes ver-

sion 9.10, version 9.10 for single con-

troller). The turbo option helps extend

the high-availability and scalability char-

acteristics of the entry-level DS4300

Express base model, and may be

added during the initial order or later as

an upgrade. Both the base model and

turbo option are designed to offer high-

performance, low-cost storage and the

ﬂexibility to grow with your business.

The DS4300 Express uses advanced

caching algorithms to help optimize

disk performance. The base dual con-

troller model is designed to deliver up

to 77,500 cached I/Os per second and

up to 400 MBps throughput in stream-

ing disk reads. Using DS4000 Storage

Manager 9.10, the DS4300 Turbo is

designed to perform up to 77,500

cached I/Os—and provides up to

768 MBps throughput.

The DS4300 Express with “ﬁbre chan-

nel” dual controller without Turbo can

support up to 56 disk drives when

using three DS4000 EXP710 Express

disk enclosures or 112 SATA disk

drives when using eight EXP100

Express Expansion Units. With the

turbo option, it can support up to

112 drives when using seven DS4000

EXP710 Express disk enclosures. The

base dual controller model offers up

to 16.8TB of Fibre Channel and up to

16 storage partitions. By adding the

turbo option, the DS4300 Express can

support up to 33.6TB of ﬁbre channel

and up to 64 storage partitions. The

DS4300 Express dual controller and

DS4300 Express Turbo offer up to

28TB of Serial ATA physical disk stor-

age capacity with the DS4000 EXP100

Express.

Other features of the turbo option

include an increased cache size of 2GB

and an auto-sensing capability to help

detect host connectivity speed. This

auto-sensing capability adds support

for 1 Gbps Fibre Channel connectivity

to the base model’s 2 Gbps Fibre

Channel interface, allowing the DS4300

Express to support a wider range of

devices and thus is designed to provide

greater interoperability. The turbo option

also helps extend the copy services

capabilities of the DS4300 Express by

including the VolumeCopy feature,

which is designed to enable full replica-

tion of logical volumes for enhanced

data management and protection. Also

available is version 9.1 with turbo

option supporting Enhanced Remote

Mirroring for replication of logical

volumes.

DS4000 Intermix feature for attachment of

Fibre Channel and Serial ATA Disk Storage

Expansion units

The IBM TotalStorage DS4500, DS4400

and DS4300 Turbo Midrange Disk

Systems have the capability to support

attachment of both DS4000 EXP710

Express Fibre Channel Disk Expansion

units and DS4000 EXP100 Express

Serial ATA Disk Expansion units concur-

rently. This feature requires the DS4500,

DS4400, or DS4300 Turbo systems be

upgraded to the DS4000 Storage
