Affordable, Redundant, Powerful Storage Intel® RAID High Availability Storage, powered by LSI* Syncro Technology, Makes Storage More Reliable, Versatile and Economical
The High Availability Challenge
Key Benefits
Today’s virtualized datacenter environment requires shared storage with mission-critical reliability. While storage area networks (SANs) satisfy this need, they are often expensive to deploy and manage. Network-attached storage (NAS) can be very affordable until adding reliability and data protection becomes necessary. This can more than double the cost. What is needed is the best of both worlds: a shared storage solution with SAN reliability at a cost similar to a direct-attached storage (DAS).
• SAN-like shared storage and failover capabilities at DAS price points • Combines server redundancy with RAID data protection to run mission-critical applications locally • Enables Windows* Server and Linux high availability capabilities and cluster topologies • Reduces the cost of building high availability server clusters by 60% and increases performance by 25%1 • Simple software upgrade to existing Intel RAID controllers
This shared storage helps to achieve numerous benefits of server virtualization. It simplifies the migration of virtual machines (VMs) among different physical servers, and highly available shared data stores help assure rapid failover of VMs in a cluster.
Other features include support for:
Intel® RAID High Availability Solution Intel RAID High Availability, powered by LSI* Syncro technology, is specifically designed to make it easier and less expensive to configure shared storage arrays with high availability and data protection. It is specifically designed to fulfill this need when implemented as a fully redundant, high-availability storage appliance. This simple software upgrade to existing RAID controllers combines two storage RAID controllers with two servers to provide a redundant, simplified server failover cluster. It reduces latency by half and reduces the cost of building high availability server clusters by 60 percent while increasing performance by 25 percent.1 IT departments may prefer Intel RAID High Availability with external disk drive connectors, which enable two ordinary rack-mounted servers to be turned into a shared storage “cluster-in-a-rack” configuration. Integrators and system vendors can take advantage of the Intel RAID High Availability with internal connectors to implement “cluster-in-a-box” shared storage appliances. Whether in the rack or the box, both configurations eliminate all single points of failure and support robust RAID data protection to make shared storage with mission-critical high availability more affordable. Intel RAID High Availability makes it easier to implement shared storage arrays with both high availability (HA) and high performance, but at a remarkably low cost. Intel RAID High Availability also affords broad flexibility to configure shared storage arrays with a mix of up to 120 physical hard disk drives and/or solid state drives (SSDs) in the HA storage domain, and up to 64 virtual drives with either shared or exclusive host access. High performance is achieved through support for an eight-lane (x8) PCI Express* bus and 6Gb/s SAS disk drive connectors, along with optional SDRAM SSD caching Intel® SSD Cache with FastPath I/O supporting write-back HA cache mirroring.
• Enables Windows* Server and Linux high availability capabilities and cluster topologies including Windows* Server 2012 and Red Hat* Enterprise Linux 6.3 • RAID levels 0, 1, 5 and 6 with RAID spans 10, 50 and 60 • SAS2208 dual-core RAID-on-Chip I/O processor and SAS controller • Single controller multipathing (failover) and load balancing • Auto resume after loss of system power during array rebuild • Write back HA cache mirroring • Intel® RAID SSD Cache is included in order to allow for the optional use of Solid State Drives as a large cache pool for the RAID controller • LSI* FastPatch technology is included for solutions that include SSD arrays. FastPath optimizes data transfer paths and error check routines to allow for low latency, high IOP performance
Summary Intel RAID High Availability delivers a combination long overdue for shared storage: High availability, high performance and low cost. IT departments can easily optimize a storage array’s configuration and capacity to meet the specific needs of an organization. Plus, Intel RAID High Availability integrates optional solid state caching to accelerate performance while providing solid data protection. And it does so at a much lower cost.
