Chapter 2: Hardware and Software Setup
This chapter explains how to set up the hardware and software for the Syncro CS 9361-8i solution and the Syncro CS
9380-8e solution with two controller nodes and shared storage. For this implementation, use a Cluster-in-a-Box (CiB)
configuration in which the two server nodes with Syncro CS controllers and the shared disk drives are installed and
connected inside a single CiB enclosure.
The Syncro CS cluster-in-a-box (CiB) system design combines two servers and a common pool of direct attached
drives within one custom-designed enclosure. After you initially set it up, the CiB system design simplifies the
deployment of two-node clusters because all components and connections are contained in one closed unit.
The Syncro CS cluster-in-a-box configuration requires a specially designed server and storage chassis that includes
two Syncro CS controller boards and multiple SAS drives selected from the LSI disk compatibility list (see the URL in
Section 1.4, Hardware Compatibility ).
2.1 Syncro CS 9361-8i Controller Kit
The LSI Syncro CS 9361-8i controller kit includes the following items:
— Two Syncro CS 9361-8i controllers
— Two CacheVault Flash Modules 04 (CVFM04) (pre-installed on the controllers)
— Two CacheVault Power Modules 02 (CVPM02)
— Two CacheVault Power Module mounting clips and hardware
— Two CacheVault Power Module extension cables
— Two low-profile brackets
— Syncro CS 9361-8i and Syncro CS 9380-8e Controllers Getting Started Guide
The Syncro CS 9361-8i controllers in the kit include the CacheVault Module Kit LSICVM02, which consists of a
CacheVault Flash Module 04 (CVFM04), a CacheVault Power Module 02 (CVPM02), a clip, and a cable.
The CVFM04 module is an Open NAND Flash Interface (ONFI) flash module that is pre-installed on the Syncro CS
controller. The CVFM04 module provides cache off-load capability to protect cached data in case of host power loss or
server failure.
The CVPM02 module is a super-capacitor pack that provides power for the backup of your data in case of host power
loss or server failure. The CVPM02 module provides both capacitor charge maintenance and capacitor health
monitoring functions similar to those of an intelligent battery backup unit.
If a power failure occurs, the CVPM02 module unit provides power to transfer the cache memory contents from DRAM
to a nonvolatile flash memory array on the CVFM04 module the next time the controller is power on. Cached data can
then be written to the storage devices.
The following figure shows a high-level diagram of a CiB Syncro CS 9361-8i CiB configuration connected to a network.
The diagram includes the details of the SAS interconnections.
NOTE The CB220 Quanta CIBs midplane has two SAS 8088 connectors. You
can connect cables from these connectors to the enclosure external
storage modules (ESMs). You should connect two cables from each
port to the two ESM modules (one cable to a module) present in the
storage enclosure.
