PRODUCT DESCRIPTION
ASUSTOR Lockerstor 4RD AS6504RD 4-Bay Rackmount NAS - 3 Years Warranty
The LOCKERSTOR 4RD (AS6504RD) is a 1U, 4-bay rackmount NAS for small and medium businesses that need redundancy in the server room. It combines an Intel Atom C3538 quad-core CPU and 8GB DDR4 (expandable to 128GB) with dual redundant 250W power supplies, four Ethernet ports and a PCIe slot for 10GbE. It runs ASUSTOR ADM and carries a 3-year warranty.
Redundant power supplies
Two 250W power supplies, so the NAS keeps running if one fails; the AS6504RS sibling has a single 250W unit.
Four network ports + PCIe for 10GbE
Two Gigabit and two 2.5-Gigabit Ethernet ports (up to 5Gbps aggregated), plus a PCIe 3.0 x8 slot (x4 link) for an optional 10GbE card, sold separately.
Up to 128GB DDR4
Ships with 8GB DDR4 and four SO-DIMM slots expandable to 128GB (4 x 32GB); a front Find Me button lights a rear service LED for locating the unit in a rack.
