Rackable Appliance Aims to Smooth Out Storage I/O Problems
Rackable Systems says its product eliminates I/O bottlenecks that slow down legacy NAS systems and delivers a single file system package that scales for large Linux data center deployments.Storage server maker Rackable Systems on Nov. 14 introduced a new cluster file system storage appliance designed specifically for large-scale Linux computing environments. The RapidScale SA3100 appliance, which attaches directly to the network, is designed to smooth out I/O bottlenecks commonly associated with legacy NAS (network-attached storage) systems and delivers a single file system package that scales inline with both capacity and performance, a spokesperson for Milpitas, Calif., company said. RapidScale provides up to tens of gigabytes per second of I/O throughput, ultimately reducing wait time and improving overall storage performance, the spokesperson said. Each RapidScale SA3100 appliance adds 8TB of storage capacity and up to 200MB per second of performance.

- Scalability: The RapidScale file system is scalable to petabytes of capacity.
- High throughput: The solution provides tens of gigabytes of throughput, delivering near-linear scaling. Performance is only limited by the number of spindles deployed in the RapidScale storage cluster.
- High IOPs: RapidScales patent-pending architecture delivers equally scaling of small-file, random access performance, satisfying the requirements of a wider range of application needs.
- Centralized management: The solution allows administrators to centrally manage all clustered storage servers from one file system.
- Easy deployment: RapidScale deploys quickly with familiar Linux administration tools. With no kernel or application modifications needed for accessing clients, administrators leverage tried-and-true Linux utilities to create and manage the RapidScale file system.
- Compatibility: Replication and backup software compatible with the XFS file system are compatible with RapidScale.
- High availability and dual-level RAID protection: Leveraging optional RapidScale HA technology, Rackable Systems RapidScale clustered file system solution delivers two independent levels of RAID protectionhardware RAID with optional hot spare inside each appliance and storage-cluster-level RAID across appliances. In case of failure of an entire appliance, the 8TB of capacity is quickly restored to a hot spare appliance in the same length of time for a single drive RAID rebuild.
