Cache Backup Module (BKM)

2

4

Backup memory modules are installed in pairs and referred to as a backup memory kit. Each module contains two batteries and either a 128 GB SSD (small kit) or a 256 GB SSD (large kit).

If the power fails, the cache is protected from data loss by the backup batteries and the cache flash memory (SSD). The batteries keep the cache active up to 32 minutes while the data is copied to the SSD.

3

• Virtual storage director (2.1 GHz)

• Virtual storage director (2.3 Ghz)

2 (1 pair)

8 (4 pairs)

A VSD can contain either an Intel Xeon 2.1 GHz or 2.3 GHz 8-core microprocessor.

The VSDs are independent of the front-end directors and back-end directors, and can be shared across them.

The VSDs must be installed in pairs and the VSDs control the front-end directors, back-end directors, PCI Express interface, local memory, and communication to the SVP.

4

Cooling fan (intake)

5

5

The five intake fans on the front of the controller pull air into the controller and distribute it across the controller components.

5

Cache Path Control Adapter (CPA)

1

4

The CPA uses the built-in switch to connect the VSDs to the front-end directors, back-end directors, and the cache backup memory. It distributes data (data routing function) and sends hot-line signals to the VSD. The shared memory is located on the first CPA cache board in each cluster in the primary controller.

Power supply

2

4

200-240 VAC input. Provides power to the controller chassis in a redundant configuration. Each power supply contains two cooling fans to ensure constant cooling if one fan fails.

Service processor (SVP)

1

2

A custom PC monitoring and controlling the storage system. It contains the Device Manager - Storage Navigator software, which configures and monitors the system. Connecting the SVP to a service center enables the storage system to be remotely monitored and maintained by the support team.

Service processor (SVP) or Hub

0

1

This space can be empty or can contain either a second SVP or a hub. If a second SVP is installed, the primary SVP is the active SVP, and the secondary SVP is the hot idle SVP with active Windows. A hub facilitates the transfer of information from the VSD pairs to the primary SVP.

Back-end director or (optional) front-end director

0 if diskless

4

Connects the HDDs, SSDs, and FMDs. It controls the data transfer between the drives and the cache.

VSP G1000, VSP G1500, and VSP F1500 support two types of back-end directors:

• Standard back-end director
• Encrypting back-end director¹

Important: Each back-end director and front-end director consists of a set of two of blades. See Flexible front-end director installation for details.

2 with drives

Front-end director (host I/O module)

1

2 to 5 with drives

A front-end director (FED) provide ports that support connectivity to the open and mainframe systems belonging to the customer. In addition, some of the FEDs support virtualization of externally attached storage, remote replication between VSP G1000, VSP G1500, and VSP F1500 and other storage systems, including communication between two Hitachi storage systems in a global active device cluster. See Front-end directors for details.

6 if diskless system

Cooling fan (exhaust)

5

5

The exhaust fans on the rear of the controller pull hot air away from the components and push it out the back of the rack.

FED or VSD slot

0

4

The slots on the controller support both front-end directors and VSDs. Both FEDs and VSDs must be installed in pairs.

OFF: If system power is on, the port is ready.

ON: Link is active.

4

Link Activity

(FC/iSCSI)

Dark (off)

Green (on)

OFF: No link activity, for three possible reasons: power is off, initialization is not completed, and if system is operational, the port is not being accessed.

ON (steady): Link is available and initialization is complete, but connection to the host has not been established.

Blinking: When the port is being accessed and data is being transferred between the host and the cache.

3

Port Status

(FICON)

Dark (off)

Green (on)

OFF: If system power is off, the port is not ready.

ON: Link is available and initialization is complete, but connection to the host has not been established.

ON: Link is active.

4

Link Activity

(FICON)

Dark (off)

Amber (on)

OFF: No link activity because either power is off, initialization is not complete, or, if the system is operational, the port is not being accessed.

ON (fast blink): When the port is being accessed and data is being transferred between the host and the cache.
