The Gluesys VTN 2400 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

    Name Value Description
    atime age 8 hours Files may be migrated to the AnyStor 500 Storage if there is no access up to 8 hours.
    high watermark 80 When 80% of Internal Cache Storage used, Migration will start automatically.
    low watermark 50 When 50% 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

    20+2 RAID6 array were created on VTN 2400 Appliance, and 2 hot spares were attached. And the 120GB SSD disk was used for secondary read cache.

    1 10G Gigabit Ethernet 1 One 10 Gigabit Ethernet port used for VTN 2400 appliance.
    2 Gigabit Ethernet 1 The AnyStor 500 Appliance is connected via 1 Gigabit Ethernet.

    Network Configuration Notes

    The VTN 2400 Appliance was attached to Load Generator directly with 10G NIC. The VTN 2400 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 VTN 2400 node has main memory that is used for the operating system and for caching data and meta-data. Main memory will be extended up to 128GB.

    Stable Storage

    The VTN 2400 has 1GB NVRAM. A user's data and meta data changes log to the NVRAM module. For the performance reason, 120G SSD is used for secondary READ cache. 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 VTN 2400 storage appliance housed in a single 4U chassis, with 24 2TB SATA disk drives. A dual-port gigabit ethernet host bus adapter was present in a PCI-e expansion slot. A 120G SSD was present in a PCI-e expansion slot and enabled with secondary filesystem cache. The storage disks were configured with RAID6(22) and hot spares(2) 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 VTN 2400 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 VTN 2400 Stoarge Appliance hardware was designed for Legacy Storage Server. A Linux/Windows OS can be installed.
