Hot-swap power supplies also permit continuous operation and avoid downtime.

Fans are also easily hot- swapped for non-disruptive service.


    FlashNAS ZFS 2U Storage System

    Winchester Systems combines durable, redundant hardware technology with OpenSolaris and the ZFS file system to provide Enterprise-level data protection and reliability at down-to-earth prices.

    Sporting controllers, power supplies and fans that are modular, redundant and hot-swappable, the FlashNAS ZFS hardware platform is purpose-built for continuous availability and long-term durability.

    The revolutionary ZFS file system adds end-to-end error detection and correction, self-healing, and advanced SSD optimization features for unsurpassed protection of data integrity throughout the storage system. Building on this foundation, Winchester Systems FlashNAS ZFS adds advanced enterprise-grade functions such as storage-pool mirroring, remote replication, data archiving and retention compliance, anti-virus scanning, and NDMP backup and migration compatibility.

    All of these capabilities are combined into a single integrated system with an easy-to-use, web based management interface. And there are no hidden, or “extra” costs to enable specific features. All functionality is available for the base system price.

    Durability, Availability & Protection

    Enterprise Class: True enterprise functionality included in a simple to deploy storage system.

    Redundant Controllers: Redundant active-active failover controllers, with automatic fail-back, deliver enterprise-class uptime.

    End-to-End Data Integrity: Self healing architecture detects and repairs silent data errors using independent multi-level checksums.

    ZFS RAID Levels: 0, 1, 5, 6, 50, 60.

    MPIO: Multi-pathing data access for automated failover and load balancing.

    Hot-Swap Components: Hot-swap controllers, disks, power supplies and fans.

    Hot-Spare Disks: Standby disks that are ready to be automatically rebuilt to replace failed disks – and disks that are signalling imminent failure.

    Expandable Storage Pools: Created from multiple RAID sets and easily expanded.

    Unlimited Snapshots: Snapshots take no additional space until contents of a file share or volume change. The number of snapshots is limited only by disk capacity.

    SSD Cache Data Acceleration: SSDs can be used as high speed cache to accelerate read and write performance.

    Data Compression: Algorithms use variable size blocks based on data characteristics and results in typical data compression of 2x to 5x.

    Remote Replication: Asynchronous replication between two FlashNAS ZFS servers via optionally encrypted link.

    Backup Software Integration: Easy integration with standard backup software and NDMP compliant applications.

    WORM: Protects files against deletion or tampering to meet regulatory data-retention and archiving requirements.

    Anti-Virus Scanning: Supports ICAP anti-virus engines to detect and quarantine viruses before they are accessed.

    CIFS/NFS/AFP Unified Security Model: Seamlessly share files across OS platforms.

    Pool Mirroring: Synch and asynch mirroring of storage pools between FlashNAS ZFS systems.

    Thin Provisioning: Create large virtual volumes and auto-allocate physical space as needed.

    Disk Roaming: Disks can be removed and reinstalled in any order – especially handy for initializing a disaster recovery site.

    Mixed NAS & SAN: Supports iSCSI volumes with LUN masking for data protection on same storage systems as NAS volumes.

    Simple GUI and CLI: Manage RAID sets, storage pools, snapshots, mirrors, replication, compression and more via web browser or command line interface.

    Enterprise Class Service: Includes 24×7 US staffed call center and next-day on-site service.

    On-Site Installation: Reasonably priced on-site installation by factory trained professionals.

    All Inclusive Pricing: Enterprise class file server with enterprise class features all included in the base price – no hidden upgrade fees.
