A stretch cluster provides a low total cost of ownership (TCO) solution by creating enterprise-class storage services on industry
standard server and storage hardware. This solution with ATTO Technology connectivity, AIC hardware and Open-E
JovianDSS software provides 24/7 uptime with business continuity for real-time, mission-critical applications enabling
organizations to virtualize these applications and maintain high-availability access. Utilizing Fibre Channel to create a high performance
storage area network (SAN) makes sure data is always synchronized between data center sites. It is important
to have reliable, predictable, low-latency links between sites in a stretch cluster; ATTO XstreamCORE® and FibreBridge® i
ntelligent bridges are building blocks that add enterprise Fibre Channel connectivity to up to 10 shelves of low cost SAS/SATA
drives while introducing up to only four microseconds of latency. When paired with standard JBOD or JBOF enclosures, ATTO i
ntelligent bridges represent an foundational data center component – one that companies can use to architect stretch cluster
solutions that enable active site balancing, downtime avoidance and Disaster Recovery with more flexibility and a lower TCO than
native Fibre Channel storage.
Disaster avoidance involves proactive behavior to circumvent an impending storage outage. Even if a partial site failure
occurs, disasters tend to affect an entire site. Disaster avoidance technologies allow for configuration of a host, cluster or
site in a fashion that keeps systems running with minimal interruption.
With downtime avoidance, virtualization technologies can move virtual machines (VMs) or virtual storage with no
interruption to service.
Disaster Recovery helps to rapidly restore services when there is an unexpected outage and the recovery time is unknown.
High Availability and fault recovery
High Availability technology reduces the length of an outage sustained by a failure and allows for rapid recovery of system
services. High Availability Clusters provide automated fault recovery in a reactive fashion, with VMs restarted as required to
recover from unplanned outages.
