Next Generation Storage Arrays
Tegile Systems is pioneering a new generation of affordable, feature-rich storage arrays that are up to 7X faster, and require up to 75% less capacity, than standard disk arrays. IT departments use these Zebi arrays to reduce the cost and increase the performance of demanding VDI, server virtualization, and file share applications.
Tegile’s patent-pending technology underpins these achievements.
Tegile’s Zebi array uniquely combines a unified SAN and NAS platform along with proprietary Metadata Accelerated Storage System (MASS) technology to realize the holy grail of storage – high performance, high capacity and high reliability at low cost. It combines this unique technology approach with best in class data protection features and an extremely friendly user interface to take storage to a whole new level of usability.
Metadata Accelerated Storage System (MASS)
Traditional disk array storage systems store data and metadata together, with metadata being interspersed with data on disks. Over time, with data being modified, deleted, and rewritten, metadata becomes very fragmented on disk. Additionally, certain storage system features, such as de-duplication, can cause metadata to multiply and grow rapidly.
Inordinate growth of metadata causes significant deterioration in a system’s behavior over time. This was the key driver behind Metadata Accelerated Storage System (MASS). With MASS, the Zebi network storage array system organizes and stores metadata, independent of the data, on high-speed devices with optimized retrieval paths. This accelerates every storage function within the system, raising the performance of near-line SAS hard disk drives to the level of extremely expensive high-RPM SAS or Fibre Channel drives.
Tegile also built in true unified access into Zebi. Both block protocols (iSCSI, Fibre Channel) and file protocols (NFS and CIFS) are equally well supported. This makes it possible, for instance, to deploy Zebi for virtualization as a Fibre Channel target to provide high-performance, low latency storage to the hypervisor, while simultaneously using the file share features of Zebi via CIFS for user file shares.
This flexibility allows customers to solve their business problems with a single storage platform. This is more effective and less expensive than attempting to pull together multiple storage platforms to satisfy their different requirements.
Optimized Hybrid Store
Along with using solid state disks (SSDs) to support MASS, Zebi integrates DRAM and Flash intelligently into the data path to create an optimized hybrid storage appliance. DRAM is used as an extremely fast level 1 read cache, while Flash SSDs are used as a second level of non-volatile read and write cache. Unlike systems which risk data loss by relying entirely on Flash for data storage, Tegile Zebi always protects user data by storing it permanently on hard disks, while using faster Flash and DRAM as high-speed cache.
Superior Data Protection
Tegile takes a holistic approach to data protection to ensure superior availability of your valuable data. Supporting multiple parity levels to help survive multiple disk failures is just the beginning. Zebi is designed from the ground up to deliver an intelligent appliance with no single point of failure. Zebi includes automated snapshot schedules for recovery points, fully redundant metadata storage, and built-in multi-node data protection with automated replication. Furthermore, replication is designed to be highly efficient, since only the incremental changes since the previous replication are transmitted over the network to the standby array.
