The Gluesys VTS 7200 appliance provides tier based NAS Storage Solution. The Internal Cache disk will be configured with SSD, SAS and SATA. Tier Policy supports "path preserve mode" function that preserves filename and migrated file path, as a result Migration Target System can serve migrated files with read only mode.

Migration Target System Example

  • Legacy NAS System
  • Amazon S3 Compatible Cloud Storage
  • Local Extend Storage

    Server Tuning

    Name Value Description
    atime age 10 hours Files may be migrated to the AnyStor 500 Storage if there is no access up to 10 hours.
    high watermark 90 When 50% of Internal Cache Storage used, Migration will start automatically.
    low watermark 70 When 20% of Internal Cache Storage used, Migration process will stop automatically.
    path preserve mode yes It will preserve Migration Path. So NFS/CIFS Clients can read files directly from AnyStor 500 NAS Storage.

    Server Tuning Notes

    3 sets of 20+2 RAID6 array were created on VTS 7200 Appliance, and 6 hot spares were attached. And the 480GB SSD disk was used for secondary read cache.

    1 10G Gigabit Ethernet 1 One 10 Gigabit Ethernet port used for VTS 7200 appliance.
    2 Gigabit Ethernet 1 The AnyStor 500 Appliance is connected via 1 Gigabit Ethernet.

    Network Configuration Notes

    The VTS 7200 Appliance was attached to Load Generator directly with 10G NIC. The VTS 7200 and AnyStor 500 were attached to a CISCO 3560G-TS-S 1G Switch.

    Benchmark Network

    There were two 10 gigabit ethernet network interfaces on storage controller. The interfaces were configured to use jumbo frames (MTU size of 9000 bytes).

    Memory Notes

    The VTS 7200 node has main memory that is used for the operating system and for caching data and meta-data. Main memory can be extended up to 512GB.

    Stable Storage

    The VTS 7200 has 1GB NVRAM. A user's data and meta data changes log to the NVRAM module. Filesystem modifying NFS operations are not acknowledged until the data has been safely stored in NVRAM. The battery backup for NVRAM ensures that any uncommitted transactions persist for at least 72 hours.

    System Under Test Configuration Notes

    The system under test consists of one VTS 7200 storage appliance housed in three 4U chassises, with 72 2TB SATA disk drives. A dual-port gigabit ethernet host bus adapter was present in a PCI-e expansion slot. A 480G SSD was present in a PCI-e expansion slot and enabled with secondary filesystem cache. The storage disks were configured with 3 sets of RAID6(20+2) and hot spares(6) by TierCat Volume Manager. The system under test was connected to 10 gigabit ethernet (cross link to Load Generator).

    Load Generator Configuration Notes

    One Load Generator (LG1) was connected to VTS 7200 storage appliance directly via 10G Ethernet.

    Uniform Access Rule Compliance

    The LG1 client hosted 10 processes. The assignment of processes to filesystems and network interfaces was done such that they were evenly divided across all filesystems and network paths to the storage controllers. The filesystem data was striped evenly across all disks.

    Other Notes

    The VTS 7200 Stoarge Appliance hardware was designed for Legacy Storage Server. A Linux/Windows OS can be installed.
