44 个盘位：一台服务器就是半个存储柜

分布式存储和大数据集群的硬件账从来不是”买多少 TB”，而是”每 U 能塞多少 TB、每 TB 花多少瓦”。xFusion 5288 V7 的回答是：4U 机箱里放 44 块 3.5 英寸盘 + 4 块 NVMe U.2。按当前 20TB 企业盘计算，单台 5288 V7 的裸容量可以超过 880 TB – 一台 4U 节点顶过去一个 12U 的存储柜，机架、线缆、交换端口全部省下来。

Core Specifications

Configuration Calculator: Match Bays to Workload

Configuration	Capacity example	Best for
44 x 3.5″ SAS/SATA	880 TB with 20TB drives	Object storage, archive, big data
24 x 3.5″ + 4 x NVMe U.2	480 TB + 30 TB flash	Distributed storage with hot tier
4 x 2.5″ + 4 x NVMe	Compact mixed build	Compute-leaning storage nodes

Every layout keeps the dual M.2 SSDs on hardware RAID for boot – the 44 data bays stay 100% available for data.

xFusion FusionServer 5288 V7 4U storage server — FusionServer 5288 V7: 4U chassis with 44 x 3.5-inch bays and 4 x NVMe U.2 for ultra-large storage.

Storage Engine: Capacity and Speed in One Box

The 5288 V7 splits storage duty by role: 44 x 3.5-inch bays handle bulk capacity at the best per-TB cost (pair them with 20TB helium drives like the Toshiba MG10ACA20TE for a full build), while 4 x NVMe U.2 SSDs serve the hot tier for metadata, index and hot data. The hardware RAID controller covers RAID 0/1/10/1E/5/50/6/60 with supercapacitor-backed cache, plus RAID level migration, drive roaming and self-diagnosis – so a drive failure or rebalance never requires a service visit.

Compute and Networking Headroom

Storage nodes are not dumb JBODs. The 5288 V7 runs 1-2 x 4th/5th Gen Xeon Scalable (385 W TDP) with 32 DDR5 DIMMs at 5600 MT/s, and two FlexIO slots take two OCP 3.0 NICs (up to 100GE each, hot swap) – enough fabric bandwidth to serve 800+ TB of capacity without saturating the network. Twelve PCIe 5.0 slots leave room for HCA, 25/100GbE adapters or up to 8 single-width GPU cards if the node doubles as a compute tier.

Security & Management

Security. Power-on/administrator passwords, TPM 2.0, security bezel, secure boot, chassis intrusion detection and RoT-based secure boot.

Management. iBMC with dedicated management GE port, Redfish/SNMP/IPMI 2.0, HTML5/VNC KVM, virtual media, Agentless monitoring and out-of-band control; optional FusionDirector adds fleet-wide automation (20x faster upgrades, 10x faster deployment, 100% asset stocktaking accuracy).

Power, Cooling & Physical

PSU: 900 W – 3000 W Platinum/Titanium, 1+1 redundancy, 12.5% lower power loss than industry average.
Cooling: 6 or 8 x hot-swappable counter-rotating fan modules in N+1 redundancy with EVAC (50% better heat dissipation).
Efficiency: algorithm-driven fan/CPU power control saves up to 8% energy.
Dimensions: 175 x 447 x 798 mm (6.89 x 17.60 x 31.42 in). Weight varies by configuration – request the exact figure with your build.

OS & Hypervisor Support

FusionOS, Windows Server, SLES, VMware ESXi, RHEL, CentOS, Oracle, Ubuntu, Debian and openEuler.
