IBM DS8000 manual 2 DS8100 Model

In the following sections, we describe these models further:

1.DS8100 Model 921

This model features a dual two-way processor complex and it includes a base frame and an optional expansion frame.

2.DS8300 Models 922 and 9A2

The DS8300 is a dual four-way processor complex with a Model 922 base frame and up to two optional Model 92E expansion frames. Model 9A2 is also a dual four-way processor complex, but it offers two IBM TotalStorage storage system Logical Partitions (LPARs) in one machine. The Model 9A2 can also be expanded with up to two Model 9AE expansion units.

6.1.2DS8100 Model 921

The DS8100 Model 921 has the following features:

￿Two processor complexes with pSeries POWER5 1.5 GHz two-way CEC each.

￿Up to 128 DDMs for a maximum disk storage capacity of 38.4 TB with 300 GB DDMs.

￿Up to 128 GB of processor memory, which was referred as cache in the ESS 800.

￿Up to 16 host adapters (HAs) with four ports per HA and 2 Gbps per port. Each port can be independently configured as either a Fibre Channel protocol (FCP) port for open systems host connection or PPRC FCP links, but also as a FICON port to connect to zSeries hosts. This totals up to 64 ports with any mix of FCP and FICON ports. ESCON host connection is also supported. But with ESCON, an HA contains only two ESCON ports. A mix of ESCON ports and FCP ports on the same HA is not possible. A DS8000 can have both ESCON adapters and FCP/FICON adapters at the same time.

The DS8100 Model 921 connects to a wide variety of host server platforms. For an up-to-date connectivity list, see:
