For today's business, protecting against downtime and data loss is a top priority. LeftHand SANs are designed to be highly available and cost-effective. LeftHand architecture clusters storage devices into a single virtual pool, automating storage management and providing continual access to business-critical information. Add a new node to your SAN and SAN/iQ® software automatically re-stripes all the data within the cluster, balancing the data load for optimal performance and reliability.

Every LeftHand SAN:

• Scales Easily with Your Business. Our storage networks scale performance along with capacity, allowing you to start with any size SAN and grow.

• Delivers the Highest Availability. The unique architecture of the LeftHand SAN eliminates any single point of failure, ensuring anytime, anywhere data access.

• Protects Your Data. Award-winning SAN/iQ software spreads multiple copies of data across the network, allowing uninterrupted access to volumes even through the loss of an entire datacenter.

Better Than Traditional SANs

Traditional SANs make you define RAID groups ahead of time by allocating the disks to a particular RAID group. Changing volume’s RAID level means taking its RAID group down for restriping, or moving the volume to a different RAID group — either way, all the applications that depend on it suffer down time during the move. Also, to support different RAID levels for different types of data, you must purchase and allocate physical disks for each, causing underutilization, creating storage islands, and forcing application downtime for copying.

 With SAN/iQ clusters, Network RAID is an attribute of each logical volume, and you can change it on the fly. This allows you to closely match your storage characteristics to your business requirements. If you change the Network RAID level for a volume, the cluster re-adjusts how it stores the volume’s blocks internally, and transparent to the applications that depend on it — all with no downtime. To accomplish this with traditional SANs means purchasing a second storage system and special asynchronous replication software.
