CHAPTER 1
System Components
The MSA2000 Family 2012sa Modular Smart Array and MSA2000 Drive Enclosure
are high-performance storage solutions that combine outstanding performance with
high reliability, availability, flexibility, and manageability.
Supported configurations include a controller enclosure with or without attached
drive enclosures. A controller enclosure can contain two controllers that interact and
provide failover capability for the data path. The controller enclosure can use SATA
or SAS disk drive modules.
This chapter provides information about the system components, and includes the
following topics:
■“System Management Software” on page 12
■“Hardware Components and LEDs” on page 13

System Management Software
Embedded management software includes a web-browser interface and the
command-line interface described below.
HP StorageWorks MSA2000 Family Storage
Management Utility (SMU)
SMU is the primary interface for configuring and managing the system. A web
server resides in each controller module. SMU enables you to manage the system
from a web browser that is properly configured and that can access a controller
module through an Ethernet connection.
Information about using SMU is in its online help and in the reference guide.
Command-Line Interface (CLI)
The embedded CLI enables you to configure and manage the system using
individual commands or command scripts through an out-of-band RS-232 or
Ethernet connection.
Information about using the CLI is in the CLI reference guide.

Table 1-5 Controller LEDs (Back) (Continued)

Chapter 1 System Components 19
Controller
module
Cache status Green Blink A Compact Flash flush or cache self-refresh
is in progress. Indicates cache activity.
• If the LED is blinking evenly, a cache
flush is in progress. When a controller
module loses power and write cache is
dirty (contains data that has not been
written to disk), the super-capacitor pack
provides backup power to flush (copy)
data from write cache to Compact Flash
memory. When cache flush is complete,
the cache transitions into self-refresh
mode.
• If the LED is blinking slowly, a cache
flush is in progress. In self-refresh mode,
if primary power is restored before the
backup power is depleted (3–30 minutes,
depending on various factors), the system
boots, finds data preserved in cache, and
writes it to disk. This means the system
can be operational within 30 seconds, and
before the typical host I/O timeout of 60
seconds at which point system failure
would cause host-application failure. If
primary power is restored after the backup
power is depleted, the system boots and
restores data to cache from Compact
Flash, which can take about 90 seconds.
Note: The cache flush and self-refresh
mechanism is an important data protection
feature; essentially four copies of user data
are preserved: one in each controller’s cache
and one in each controller’s Compact Flash.
Controller
module
Host activity Green Off The host ports have no I/O activity.
Blink At least one host port has I/O activity.
