Product Description

This Dell PowerEdge R740XD2 is Dell 14Gen 2U large-capacity storage-focused rack server, customized with full 24-bay 3.5’’ LFF hard disk layout, specially built for enterprise centralized NAS, long-term cold data archive, video monitoring storage and enterprise backup pool deployment. Equipped with dual Intel Xeon Silver 4210 2nd Gen Cascade Lake CPU, total 128GB DDR4 ECC RDIMM(32G×4) enterprise memory, full-populated 24×24TB high-capacity SATA enterprise HDD, original Dell PERC H355 hardware RAID controller plus dual hot-plug 750W redundant platinum PSU, total raw storage up to 576TB to satisfy PB-level bulk data storage demands.

Computation platform adopts dual Xeon Silver 4210:10C20T per chip, base 2.2GHz, max turbo 3.2GHz,13.75MB L3 Cache,85W TDP, dual CPU total 20 cores & 40 threads to handle massive metadata calculation, multi-user concurrent file access and storage pool service steadily 7×24hrs. Matched 128GB DDR4 2666MT/s ECC registered memory avoids memory error downtime under heavy I/O workload; motherboard carries 16 DDR4 slots, maximum expandable to 512GB RAM for later business upgrade.

Core highlight of R740XD2:2U compact cabinet preinstalled full 24×3.5’’ hot-swap drive bays (front 12+mid 12), fully loaded with 24TB enterprise mechanical HDD×24pcs, total raw capacity reach 576TB, ideal for constructing large-scale file storage cluster, long-cycle video archive and offline cold data warehouse. Original PERC H355 PCIe RAID adapter supports hardware RAID0/1/10 & JBOD non-raid mode, clients freely configure disk array: adopt RAID1 for core important data redundancy or JBOD to utilize full disk raw capacity for ultra-large storage pool, native 12Gbps SAS/SATA transmission compatible with all mainstream enterprise HDD/SSD.

Power system configured with dual redundant hot-swap 750W high-efficiency power supply, single PSU can independently support full 24-disk running load; dual redundant design eliminates sudden shutdown risk caused by single power source breakdown, cost-effective power match for full-populated high-capacity HDD array long-term stable operation. Embedded iDRAC9 out-of-band remote management, support remote power control, hardware real-time monitoring, fault warning and offline firmware upgrade, greatly reduce daily IDC maintenance cost.

Pre-full-function tested cost-effective refurbished storage server solution, widely adopted by medium & large enterprise IT department, security monitoring engineering company, IDC storage leasing provider and cloud backup service vendor to build low-cost high-density storage infrastructure.
