IBM System Storage DS3500: Introduction and Implementation Guide
2.1 IBM System Storage Portfolio
IBM has brought together into one family, known as the DS family, a broad range of disk
systems to help small to large size enterprises select the right solutions for their needs. The
DS family combines the high-performance IBM System Storage DS8000 Series of enterprise
servers, with the DS5000 series of mid-range systems, and the DS3000 entry level systems.
The DS3000 series consist of two new major products; the DS3500 and the DS3950. Both of
these products are a good fit for the entry to mid-range SAN and direct attach market space.
With the common Storage Manager being shared by these new DS3000 storage systems and
the DS5000 storage systems there is a smooth link into the DS5000 series systems, with
remote mirroring and copy services features being shared by these two platforms. The
DS3500 and the DS3950 offer robust functionality, exceptional reliability and availability with
the common ease of storage management being shared by all. The overall positioning of
these new DS3000 series products within the IBM System Storage DS® family is shown in
Figure 2-1.

2.2 DS3500 product models
The new IBM System Storage DS3500 series storage subsystems support up to two
redundant RAID controllers in either a twelve or twenty four drive configuration. The models
for the storage servers are: DS3512 and DS3524. There are also two models of drive
expansion chassis (a twelve and a twenty four drive) that can be attached to either of the
storage subsystems. The models for these are: EXP3512 and EXP3524. The new DS3500
models provides a number of new capabilities from the previous generations. The
enhancements are:
Allows for one storage subsystem to be able to perform in the environments of the three
legacy DS3000 family members, with support options for SAS, iSCSI and fiber channel
host connections.
With this new generation we have the marriage of the DS3000 and the DS5000 Storage
Manager and firmware releases, allowing for a common management console to support
the entry and midrange DS families.
Adds the Enhanced Remote Mirroring (ERM) Premium Feature to the DS3000 line
