The unit shown is a full data center rack using two separate FlashNAS ZFS ZX-3U16 redundant controller systems, each with 256 six-terabyte disk drives. This is a high performance, high resiliency configuration in a single rack that supports 3,072 TB and still has space for two UPS systems.


    FlashNAS ZFS 3U 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.
