Asustor Lockerstor 4RD NAS Rack (1U) Ethernet LAN Grey C3538

Cost-effective 2.5GbE 1U Rackmount ServerA thin 1U rack 2.5GbE server providing stable performance and four bays for expandable and easy SATA storage. The Lockerstor 4RS and 4RD bring expandability by bringing PCI Express capabilities, creating one of the most flexible and lightweight solutions for small businesses.Enterprise Grade Quad-Core Intel Atom CPU and DDR4 RAMEquipped with the new Quad-Core Intel Atom C3538 that is clocked at 2.1GHz and combined with more than 8GB of DDR4 RAM makes for an ultra-fast, ultra-smooth file sharing experience for your office.Enterprise BackupThe Lockerstor RD has complete backup and safety mechanisms by including dual backup power supplies for safety while including four Ethernet ports for additional performance and redundancy. Two Gigabit and two 2.5-Gigabit Ethernet ports adorn the rear of the NAS, ensuring that everyone can access their files quickly and efficiently. The Lockerstor RD makes no sacrifices by ensuring zero downtime if a port or power supply is offline. Find Me Function and Service Light for Server RoomsIn enterprise environments, storage devices are commonly placed together in a server room. In order to allow administrators to quickly find the NAS from among many servers the Lockerstor 4RS/RD(1U) provides a dedicated button on front panel. When this button is pressed, the LED service light on the rear panel of the NAS will light up. ASUSTOR also offers the mobile NAS management app, AiMaster which provides the exclusive Find Me function. When Find Me is activated, the system status light on the front of the NAS will flash and the system buzzer will sound, helping users to quickly find the NAS.Agile ExpandabilityThe ASUSTOR Lockerstor 4RD rackmount series prepares you for the needs of tomorrow. PCIe expansion enables 10-Gigabit Ethernet can be installed to increase performance and expandability. Combine the Ethernet ports and connect to a 2.5-Gigabit Ethernet switch to take advantage of extreme speeds. Break free from restrictions with the Lockerstor 4RD.Efficient, Redundant and PowerfulThe Lockerstor 4RD contains four Ethernet ports. Two are Gigabit and two are 2.5-Gigabit Ethernet. Combine the two 2.5-Gigabit Ethernet ports to increase performance and redundancy. Link aggregation increases performance to up to 5 gbps while also ensuring zero downtime in the event of one port going offline.Expand your storage spaceA professional grade NAS needs to be equipped with a diverse array of expansion functionality. In addition to the 4 drive bays, we have also included 4 USB 3.2 ports, allowing you to create a tailored storage space for both your work and entertainment needs.24/7 Reliability and DurabilityAll ASUSTOR NAS are designed for and are suitable for 24/7 use. ASUSTOR NAS devices have also undergone rigorous tests, such as drop tests and burn tests to test durability in extreme conditions. Heatsinks were added to sensitive components to dissipate heat, helping to maintain the longevity of the device.Protected From RansomwareThe Lockerstor comes with the most up-to-date version of ADM to help protect against ransomware attacks. Snapshot Center and Btrfs provide the ability to efficiently create snapshots to protect and easily restore lost data. Other security features found on the Lockerstor are the ability to create one or more replacement administrator accounts, a firewall by ADM Defender that features blacklists and whitelists, the ability to change default ports, disable SSH and Terminal to prevent remote attacks. MyArchive cold storage hard drive security can also be increased by implementing AES 256bit encryption.
