RASILIENT Systems designs and manufacturers the RASTOR line of standards-based, open architecture, storage solutions that integrate custom-tuned Linux software. While embedded hardware solutions can often be a generation behind in memory and bus technologies, the RASTOR 7500 utilizes easily extensible software for tasks that range from RAID level processing to iSCSI traffic aggregation.
RASILIENT’s RASTOR storage arrays rely on software to provide RAID redundancy, provision virtual disk volumes, and manage iSCSI connectivity. For enterprise-class networking, the RASILIENT software balances iSCSI traffic load and failover using multiple NICs, while simplifying client management by presenting a single IP address.
RASILIENT's load balancing software works at the iSCSI network layer using an iSCSI protocol redirect feature, which was created to handle target devices that were busy or undergoing maintenance. This technique is compatible with Microsoft's MPIO implementation on client initiators, for which RASILIENT also provides support so that clients can establish multiple connections for failover redundancy.
RASILIENT’s RASOS
software allows the system to easily mix and match hardware modules in order to tune system options. In particular, one of the RASTOR 7500 systems tested by OpenBench Labs utilized high rotational speed (15000-rpm) SAS disks to provide an optimal environment for applications oriented towards transaction-processing such as MS Exchange or Oracle. On the other hand, our second RASTOR 7500 came equipped with 24 750GB SATA drives for an optimal platform for digital content and Web 2.0 applications for which large files and streaming I/O are defining characteristics. As a result, RASILIENT can provide OEMs with a low-cost, enterprise-class storage solution.
