Achieve continuous application uptime and enterprise-level data protection that is also
simple and cost-effective with Avago Syncro solutions. Developed for Cluster-in-a-Box
systems, the Syncro 9361-8i provides high-availability features, consistent with Storage Area
Networks (SAN), at a cost and support model consistent with Direct Attached Storage (DAS)
environments. Small and medium businesses, remote offices, and data centers can all utilize
existing administrative infrastructure while ensuring critical applications remain up and
running.
The Next Generation of High Availability Direct Attached Storage
The Avago Syncro solution uses a self-contained Serial Attached SCSI (SAS) interconnect
to share storage and communicate between server nodes. This enterprise-level storage
medium allows each Syncro controller to measure the opposing controller’s heartbeat while
maintaining coherency of WRITE-back cache.
The 12Gb/s Avago Syncro 9361-8i delivers continuous application availability and shared
storage with twice the SAS throughput of the previous generation. Doubling the speed of the
SAS bus means more consistent heartbeat monitoring and reduced cache transfer occupancy,
while moving twice the data from storage in the same amount of time.
Reduced Footprint Cluster-in-a-Box
Controlling resource costs is paramount to the success of any business. Data centers, small and
large, control costs by managing server power, space and cooling requirements. Cluster-in-a-
Box delivers on data center cost requirements by providing multiple server nodes in a single,
reduced form factor chassis. These self-contained server clusters share common components,
minimizing the necessary power and cooling required for maintaining multiple single-node
servers.
Coherent Caching for Performance Acceleration
In the event of a primary server failure, applications are transferred to run on a secondary
server node. The secondary server will need access to the Syncro controller’s WRITE-back
data from the primary server in order to prevent data loss, and allow the applications to run
continuously. The Syncro cache coherency maintains a mirror copy of the primary server’s
controller WRITE-back cache data on the secondary server’s controller. The high-speed SAS
interconnect provides a direct link for cache data mirroring between Syncro controllers. This
optimal solution protects data and maintains application continuity while accelerating WRITE
performance.
