6.1 DS8000 highlights

The DS8000 is a member of the DS product family. It offers disk storage servers with high performance and has the capability to scale very well to the highest disk storage capacities. The scalability is designed to support continuous operations.

The DS8000 series models follow the 2105 (ESS 800) as device type 2107 and are based on IBM POWER5 server technology.

The DS8000 series models consist of a storage unit and one or two management consoles. A graphical user interface (GUI) or the command-line interface (CLI) allows a storage administrator to configure and logically partition storage.

The DS8000 series currently offers two models with base and expansion units to configure storage servers that meet the client’s performance and capacity requirements.

6.1.1 Model naming conventions

Before we get into the details about each model, we start with an explanation of the model naming conventions in the DS8000.

The DS8000 has three models at general availability (GA), model 921, 922, and 9A2. The difference in models is the number of processors and the capability of storage system LPARs. You can also order expansion frames with the base frame. The expansion frame is described as a model 92E or 9AE.

The last position of the three characters means the number of 2-way processors on each processor complex (xx1 means 2-way and xx2 means 4-way, xxE means expansion frame (no processors). The middle position of the three characters means LPAR or Non-LPAR model (x2x means non-LPAR model and xAx means LPAR model).

We summarize these rules in Figure 6-1.

Model Naming Conventions

9xy	Y=1	Y=2	Y=E
X=2	Non LPAR/2-way	Non LPAR/4-way	Non LPAR Expansion
X=a	N/A	LPAR 4-way	LPAR Expansion

For example,

921: Non-LPAR / 2-way base frame 9AE : LPAR / Expansion frame
