FlexStor 400md

8TB to 48TB - 4 Drive 1U NAS+iSCSI Storage Appliance

The FlexStor 400md Octa-Core Xeon RAID NAS+iSCSI rackmount storage appliance incorporates storage capacities of 8TB to 48TB with the latest RAID, NAS and iSCSI technologies. High performance features include the latest 8 to 22-core Broadwell-EP Xeons in dual processor configurations, up to 3TB of DDR4 system memory, and teamed 1 Gigabit or 10 Gigabit Ethernet connectivity.

This fault-tolerant data storage comes in a convenient, space-saving 1U rackmount chassis with hot-swappable drives and trays. Your data is protected with your choice of RAID 0, 1, 5, 6, 10 and JBOD across four hot-swappable SAS disk drives on an ultra high-performance 12Gbps SAS hardware RAID controller. An optional RAID cache flash memory backup module helps protect against data loss in the event of an environmental power failure.

A 750 Watt dual redundant 80-PLUSŪ Platinum 94.14% high-efficiency certified power supply with hot-swappable modules ensures continuous up-time and reduced electrical consumption.

Our base configuration provides quad 1 Gigabit ports teamed together and load-balanced for 4Gb of NAS and iSCSI connectivity. Want 10Gb instead? No problem with a very affordable upgrade to our on-board quad 10Gb configuration or choose from a variety of 10Gb Ethernet server adapters with RJ-45, SFP+, SR Optical, or LR Optical connectivity.

FlexStor appliances are extremely flexible and can utilize your existing SAS or Fibre Channel-attached storage subsystems. Just select one or more of our optional SAS and FC host bus adapters to rapidly expand your new NAS and iSCSI storage pool.

FlexStor NAS+iSCSI storage appliances are powered by Windows Storage Server 2016 Standard Edition 64-bit operating system. Windows Storage Server 2016 provides both network file-based shared storage (NFS) as well as iSCSI target block storage. Windows Storage Server's Resilient File System (ReFS) improves data integrity, availability and scalability.

Windows Storage Server 2016 supports a wide variety of robust features such as thin provisioning with just-in-time allocations, data deduplication to massively reduce the primary storage footprint on NTFS data volumes, and BranchCache to optimize performance over the WAN. Since there are no license limits on the number of connections, there is no need to purchase expensive licenses for each of your host systems.

FlexStor NAS+iSCSI storage appliances are perfect for adding storage to a new or existing virtual environment. Enhanced support for Hyper-V includes shared VHDs (Virtual Hard Disks), resizing of VHDs while a Virtual Machine is running, storage Quality of Service (Qos), as wells as improved performance for live migrations and cross-version live-migrations. An improved iSCSI target now supports VHDX (VHD 2.0) for capacities up to 64TB and supports SMI-S to enable end-to-end provisioning.

FlexStor's NFS network-attached storage protocol can be used for backend storage for Virtual Machines running on VMware ESX or ESXi.

The FlexStor 400md NAS+iSCSI rackmount storage appliance is a great fit for small business or home offices that are looking for a robust storage solution with redundancy to protect your data and prevent downtime combined with the latest in storage management software, but in an affordable package.
