Storage Servers — Dell PowerEdge for SDS, Backup & All-Flash
A shortlist of brand-new, current-generation Dell PowerEdge rack servers chosen for drive capacity and storage throughput. Whether you need terabytes of bulk HDD for backup and archive, or a dense Gen5 NVMe node for software-defined storage and scale-out databases, the models below cover both — on a single socket to save software licensing, or dual sockets for maximum throughput. Browse our Intel Xeon servers and AMD EPYC servers for the full ranges.

Choose by workload
Backup, archive & cold data
Maximise low-cost terabytes with up to twelve 3.5-inch enterprise drives in one array.
SDS, databases & fast tier
Pack in Gen5 E3.S or U.2 NVMe for the lowest latency and highest IOPS.
Lowest licensed-node cost
Up to 144 cores on one socket means one software licence per storage node — ideal for per-socket licensed SDS and virtualisation stacks.

Storage server questions
Which Dell PowerEdge is best for a storage server?
For bulk capacity on a single licensed node, the R570 takes 12 × 3.5-inch drives (up to 384 TB). For an all-flash node, the R770 supports up to 44 E3.S NVMe devices, while the R7725xd is purpose-built around 24 U.2 Gen5 drives. The right choice depends on your capacity, media and licensing requirements.
What is the difference between a storage server and a regular server?
A storage server is configured around drive bays, RAID/HBA controllers and storage throughput rather than raw CPU or GPU. Models such as the R570 and R7725 use chassis that accept many large or flash drives, making them suited to software-defined storage, backup and archival roles. A general-purpose server typically has fewer bays and is optimised for compute or virtualisation.
How many drives can the R570 hold?
Up to 12 × 3.5-inch SATA drives for 384 TB in a single RAID array, or on all-flash up to 32 front E3.S Gen5 NVMe plus 4 rear E3.S devices (36 total). It also supports 8, 16 or 24 × 2.5-inch drives depending on the backplane chosen.
Should a software-defined storage node be single or dual socket?
Single-socket models like the R570 give up to 144 cores under one software licence, lowering per-node licensing cost for many SDS stacks. Dual-socket models like the R770 or R7725 add CPU and memory bandwidth for very high-throughput or densely consolidated clusters. Choose based on your workload and how your storage software is licensed.
Can a storage server also run GPUs?
Yes. The R570 supports up to three 400W double-width or four 75W single-width accelerators, so a capacity node can also handle inference or GPU-accelerated tasks. Confirm specific accelerator compatibility with your chosen configuration when requesting a quote.
What warranty and lead time apply?
Every storage server is brand-new and covered by a 3-year warranty from Beijing Xinchuan Technology Co., Ltd. Configured builds are typically quoted with confirmed SKUs, lead time and export pricing within one working day.
