    FlashStation FS3400

    Fueling IT transformation for small and midsize businesses

    Lightning speed with lower TCO

    Featuring an 8-core CPU and 16GB ECC RDIMM memory, FS3400 provides more than 137,000 4K random write IOPS, meeting the needs for real-time analytics, online transaction processing, and mission-critical database services.1 With built-in 10GbE Ethernet, PCIe expansion, and the support of various SAS and SATA drives, FS3400 delivers flexible and economical all-flash server deployment on demand.


    Intel Xeon D-1541 8 Core 2.1 GHz


    16GB DDR4 ECC RDIMM, up to 128GB


    1 x PCIe 3.0 for 25/40GbE NIC's expansion


    Up to 72 x SAS/SATA drives

    RAID F1

    Due to the peculiarities of SSD and RAID technology, a common challenge lies in how to prevent all of the drives from failing at the same time because of the evenly distributed workload. RAID F1 alleviates this problem with a specially designed algorithm to unevenly distribute workload to drives, enhancing the resilience of the storage pool and ensuring your data remains safe.
