ISE User GuideUser Guide Introduction
g. Background parity scan: Provides enhanced data integrity by employing an embedded function to auto-
matically check all data for RAID parity consistency and flag inconsistent data with a media error.
h. Embedded Web service: Built-in Web browser and management tool, Orchestrator, that facilitates control
of ISE systems, eliminating the need for a separate management server.
i. LUN Expansion: As volume space needs increase, individual LUNs can be expanded.
j. ActiveWatch: Provides full telemetry.
Components
The ISE consists of six major components as shown in the following figure (Figure 1) plus an active bezel.
Figure 1. ISE Major Components
These major components are:
1. Two DataPacs, containing multiple drives in sealed assemblies
2. One System status module
3. Two Managed Reliability Controllers (MRCs), providing control and value-added features
4. Two emergency power units, made up of supercapacitors, capable of providing power to write-back cache
for up to one year
5. One chassis, custom-designed to house the active components of the ISE
6. Two power supply units with blowers, providing a redundant power source
Of the above listed components, all but numbers 2 and 5 are Field Replaceable Units (FRU). Additionally, the
ISE contains one to eight more FRUs; they are the Small Form-Factor Pluggable (SFP) Fibre Channel
connectors as described below.
