QNAP TS-421 - Specifications
  • The TS-421 is a cost-effective networked storage center incorporating high reliability and scalability. Featuring cross-platform file sharing, comprehensive backup solutions, iSCSI and virtualization applications, and many other practical business applications, the TS-421 is the ideal choice for SMBs to store and secure the growing business data as a reliable private cloud.

    Comprehensive virtualization support
    The TS-421 supports VMware® ESXi, Citrix® XenServer, Microsoft® Hyper-V and Windows Server 2012, and also supports advanced functions including SPC-3, MPIO and MC/S, enabling flexible deployment and management for virtualization needs. The TS-421 supports VMware VAAI to increase performance by offloading ESXi server loading, and supports QNAP vSphere Client plug-in to provide enhanced operational efficiency in managing virtualization applications.

    Fast Disaster Recovery with Snapshots
    The TS-531X supports block-based Snapshots, which can record and save the state of the file system and the metadata of the files outside the file system at any time. In the event of an unexpected NAS failure or if struck by a ransomware attack, the snapshots remain intact, allowing you to quickly and easily restore the system back to a previous normal state. You can preserve and restore multiple versions of the same file, folder or even the entire volume. The TS-531X supports up to 64 snapshots per volume or LUN (up to 256 in total). Snapshot Replica facilitates double protection that replicates snapshots to a remote QNAP NAS or server.

    Disaster recovery solutions bring peace of mind
    The TS-421 offers various data recovery options. RTRR (Real-Time Remote Replication) supports real time or scheduled data backup to remote Turbo NAS or FTP servers and synchronizes files to remote folders from local folders with better backup efficiency and reduced backup time. The TS-421 also supports rsync protocol to back up data to remote servers on a scheduled basis. Data can also be backed up to and restored from a range of cloud storage services, including Amazon® S3, ElephantDrive®, Dropbox® and Google Cloud Storage. Key Benefits
