4 Bay Diskless NAS
Intel Atom Quad Core 2.4GHz, 4GB RAM
U4-211 - PRODUCTS
Enterprise-class 4-bay networked storage server
Highly scalable storage server, designed to meet the requirements of enterprise virtualization, data-intensive applications and service continuity.
Powerful storage solution
Featuring Intel Atom C3538 2.1GHz quad-core processor, 4GB DDR4L, 2 Gigabit network interfaces. Designed for flexible storage management, it offers over 500000IOPS and 1000MB per second continuous storage.
Configure four DDR4 slots to support up to 16GB of memory modules with total memory up to 64GB; configure three PCI-E3.0 16X expansion slots for expansion of 10 Gigabit network cards (2 SFP + ports) and hard array RAID cards.
Fast and stable
Equipped with 2 network interfaces and the Link Aggregation function, the server access will not be interrupted even if a network interface fails online, greatly reducing the probability of online interruption without warning. In addition, the Link Aggregation function breaks through the limitation of network transmission speed of a single network interface and has the on-load balancing function of automatically balancing network traffic, thus providing stable data transmission for customers.
SSD cache technology
Hard disks, though large in capacity and cost-effective, are not as fast as SSDs. The use of SSD cache technology in hard disk arrays will optimize the response speed when accessing data and improve transmission performance by about 25%.
Easy management, security and worry-free
TOS enterprise version provides a graphical interface that allows you to flexibly manage user accounts and storage space, and provides you with tight server security and optimized storage space management. Alert notifications can be sent to keep you informed of server status.
