Asustor Lockerstor 4RD AS6504RD — 4-Bay 1U Rackmount NAS

Redundant Dual PSUIntel Atom C3538 Quad-Core8GB DDR4 (to 128GB)2x 2.5GbE + 2x 1GbE

The Asustor Lockerstor 4RD AS6504RD is a diskless 4-bay 1U rackmount NAS powered by a quad-core Intel Atom C3538 processor with 8GB of DDR4 memory, built for small and medium businesses that need reliable, always-on shared storage in a rack. Supplied under part number 90-AS6504RD2-ME30 (EAN 4710474831357), it combines four SATA III bays with dual 2.5GbE plus dual 1GbE networking and, crucially, two redundant power supplies so the unit keeps running if one PSU fails. Typically in stock with fast delivery across Cyprus.

Before you buy — ships diskless
The AS6504RD is supplied as an enclosure only; SATA drives are sold separately (choose NAS-rated drives). It is a deep 515mm 1U chassis — check your rack depth and use a rail kit (sold separately). There is no onboard M.2; SSD cache uses SATA SSDs in the bays, and 10GbE requires an add-in card in the PCIe slot.

Best For

Always-on business file serving with PSU redundancy
Rack deployments needing zero-downtime power
Link-aggregated 2.5GbE for multi-user access
Virtualization storage over iSCSI or NFS
Surveillance for up to 64 IP cameras
Windows AD / LDAP managed environments

Key Features

 
Redundant Dual Power Supplies
Two 250W power supplies keep the NAS running without interruption if one PSU goes offline, the key advantage over the single-PSU AS6504RS.
 
Intel Atom C3538 Quad-Core
A reliable 2.1GHz server-class Atom CPU with hardware encryption, paired with 8GB DDR4 expandable up to 128GB for demanding business workloads.
 
Four-Port Flexible Networking
Two 2.5GbE and two 1GbE ports support link aggregation up to 5Gbps with failover, and a PCIe slot accepts a 10GbE card for even more bandwidth.
 
Enterprise ADM Software
ADM adds Snapshot Center, Btrfs, iSCSI/IP-SAN, VMware/Citrix/Hyper-V support, Windows AD/LDAP and comprehensive backup for business IT.

Frequently Asked Questions

Does the AS6504RD come with drives or rails?
No. It ships diskless as a 4-bay enclosure and the rail kit is sold separately. Add NAS-rated SATA drives to build your array, and check your rack can take the 515mm depth.
What is the difference between the AS6504RD and AS6504RS?
Both are 4-bay 1U Lockerstor rackmounts with the same Intel Atom C3538 and networking. The AS6504RD has two redundant power supplies for zero-downtime, while the AS6504RS uses a single PSU.
Can I add 10GbE networking?
Yes. Alongside the four onboard ports (2x 2.5GbE + 2x 1GbE), the PCIe 3.0 slot accepts a 10-Gigabit Ethernet card such as the ASUSTOR AS-T10G2 for higher throughput.
Is it suitable for virtualization and backup?
Yes. The AS6504RD is VMware, Citrix and Hyper-V ready over iSCSI/IP-SAN and NFS, and ADM includes Snapshot Center and multiple cloud and local backup options.
Singular Expert Insight
The Lockerstor 4RD is the choice when uptime matters: its dual redundant power supplies set it apart from the otherwise identical single-PSU AS6504RS, making it well suited to server rooms that cannot tolerate downtime. If you need more than four bays in the same family, step up to the 12-bay AS6512RD. Populate the bays with reliable NAS-rated hard drives, and compare it against other rack and desktop options in the full range of NAS and RAID storage appliances.

Buyer’s Guide

Buy it if
You need a 4-bay 1U rack NAS with redundant power for zero-downtime, flexible 2.5GbE/1GbE ports and a 10GbE upgrade path.
Skip it if
You do not need redundant PSUs (the AS6504RS costs less), or you want built-in 10GbE or a shallow-depth chassis for a small cabinet.
Also consider
The single-PSU AS6504RS for lower cost, or the 12-bay AS6512RD if you need more capacity in the same rackmount family.
