01High Performance
EonStor DS 4000U delivers extremely high performance with U.2 NVMe SSD. Each appliance can hold 24 U.2 SSDs, providing an extremely high IOPS at 1000K and a throughput at 11GB/s, which allows the system to quickly respond to multiple I/O requests of virtual machines, HPC servers, databases, etc.
02High Scalability
EonStor DS U.2 NVMe Storage is highly scalable by adding expansion enclosures (JBODs) to
expand capacity. It is scalable up to 448*drives, including both SSDs and HDDs.
03High Efficiency
EonStor DS U.2 NVMe Storage supports hybrid storage, and with the automated storage
tiering function, EonStor DS U.2 NVMe Storage can automatically leverage the high throughput and low latency feature of U.2 NVMe SSDs to deliver faster performance for
frequently accessed data, while making better use of HDDs in the expansion enclosure
as data backup media, thereby boosting system performance and reducing the cost of ownership.
04High Flexibility
EonStor DS U.2 NVMe Storage supports the modular I/O card – Host Board – to satisfy different environment needs, including 8/16/32 Gb/s Fibre Channel (FC), 1/10/25/40 Gb/s
for iSCSI and 12Gb/s SAS host interface.
05Complete Data Protection and Backup
EonStor DS U.2 NVMe Storage offers multiple data protection designs to guarantee that data are tightly protected. For hard disks, EonStor DS U.2 NVMe Storage incorporates Infortrend's unique RAID technology which helps the system run normally while ensuring your data is fully protected even when the hard disk gets damaged.
06High Reliability
From power supplies, fans, controllers, to host boards, the modular design of all these hardware components lowers maintenance complexity and provides fast, precise technical support and RMA services, keeping EonStor DS U.2 NVMe Storage safe from any downtime to maintain non-stop services and increase productivity and competitiveness.
07Intelligent Management of Drives
EonStor DS U.2 NVMe Storage has an intelligent algorithm that handles the data to be written in the storage appliance. The algorithm not only reduces the total amount of writes on an SSD to prolong its lifespan, but also prevents multiple SSDs from failing at the time and causing data loss. In addition, as EonStor DS U.2 NVMe Storage monitors SSD status in real time, it can estimate its remaining lifespan and send a notification to remind to replace the SSD which is about to fail.
08Easy Management
With the constant evolution of storage platforms, EonStor DS U.2 NVMe Storage adopts the SANWatch management software to assist customers to improve storage and service efficiency for increased productivity. The intuitive design of its interface allows for centralized management of multiple appliances, monitoring of performance and capacity usage, and completing of all related system configurations.
