FlexStor 400ms

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

The FlexStor 400ms 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 Xeon processor, up to 32GB 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 500 Watt dual redundant 80-PLUSŪ Platinum 94.1% high-efficiency certified power supply with hot-swappable modules ensures continuous up-time and reduced electrical consumption.

Our base configuration provides dual 1 Gigabit ports teamed together and load-balanced for 2Gb of NAS and iSCSI connectivity. Choose from a variety of additional 1Gb or 10Gb Ethernet server adapters with RJ-45, SFP+, SR Optical, or LR Optical connectivity.

FlexStor 400ms NAS+iSCSI storage appliances are powered by Windows Storage Server 2016 Workgroup 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 Workgroup supports a wide variety of robust features such as thin provisioning with just-in-time allocations, and BranchCache P2P to optimize performance over the WAN.

FlexStor NAS+iSCSI storage appliances are perfect for adding storage to a new or existing virtual environment. Enhanced backend storage support for Hyper-V environments 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 400ms 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.
