4 路一定要 4U 吗？2U 塞进四颗处理器的密度账
四路服务器长期被等同于”庞然大物”——4U 机箱、4 个电源域、占满半个机柜。xFusion 2488H V7 打破这个默认：2U 机箱里装下 4 颗第 4 代 Intel Xeon Scalable 处理器（单颗最高 60 核/120 线程、350W TDP）和 64 条 DDR5 DIMM。对 IDC、云计算、企业和电信客户来说，同样的 4 路性能只占一半机架高度——密度翻倍，机柜利用率翻倍，每 U 的算力成本随之下降。
它的工作负载画像也很清晰：数据库、虚拟化、内存计算。64 条 DDR5 槽位意味着最多 16 TB 内存（按 256GB 模块），这正是内存计算和大型虚拟化池需要的内存天花板，同时 2U 形态让横向扩展不再被机架空间卡住。

Memory-First Design for In-Memory Workloads
The 2488H V7’s differentiator is the 64-DIMM memory subsystem. In-memory computing, large virtualization pools and database caching all scale with RAM capacity, and 16 TB per node keeps the working set local – no cluster partitioning, no network round-trips for data. Pair it with the AI memory fault self-healing engine, which predicts and contains memory errors before they crash a workload and cuts system downtime by 66% – on a 4-socket node running hundreds of VMs, that reliability margin is the whole game.
Expansion and Networking
Ten PCIe slots (one FlexIO slot dedicated to the OCP 3.0 NIC plus nine standard slots) cover HCA, dual-port NIC and storage controllers. The OCP 3.0 NIC supports GE/10GE/25GE/100GE line rates with orderly hot swap – upgrade the fabric from 25G to 100G by swapping one card, not the server. Drive layouts range from 8 to 25 x 2.5-inch SAS/SATA, with an 8 x NVMe SSD option for flash-heavy database tiers; dual M.2 SSDs with hardware RAID handle boot duty off the data bays.
Security & Management
Security. Power-on and administrator passwords, TPM 2.0, security bezel, secure boot, chassis intrusion detection and Root-of-Trust-based secure boot that validates every firmware layer.
Management. The integrated iBMC chip carries a dedicated management GE port and supports Redfish, SNMP and IPMI 2.0, with an HTML5/VNC KVM remote console, virtual media, Agentless monitoring and out-of-band control. The optional FusionDirector management platform adds fleet automation: automatic version push (20x faster upgrades), 75% tool-assisted deployment steps (10x faster rollout) and 100% accurate asset stocktaking with cross-vendor takeover.
Power, Cooling & Physical
- PSU: 900 W / 1200 W / 1500 W / 2000 W / 3000 W Platinum/Titanium hot-swappable, 1+1 redundancy, with industry-leading conversion efficiency (12.5% lower power loss than industry average).
- Cooling: 6 x hot-swappable counter-rotating fans in N+1 redundancy; Advanced Extended Volume Air Cooling (EVAC) delivers 50% better heat dissipation than a single heat sink.
- Efficiency: algorithm-driven lowest-power fan/CPU control saves up to 8% energy vs industry average.
- Dimensions: 86.1 x 447 x 898 mm (3.39 x 17.60 x 35.35 in). Weight varies by configuration – request the exact figure with your build.
OS & Hypervisor Support
FusionOS, Microsoft Windows Server, SUSE Linux Enterprise Server, VMware ESXi, Red Hat Enterprise Linux, Oracle, Ubuntu and openEuler – every mainstream enterprise OS covered.

Comparing 4-socket platforms? The Dell PowerEdge R960 offers the 4U scale-up alternative; for max storage density see the xFusion 5288 V7. As an authorized xFusion partner we offer factory-direct pricing, custom configuration, 3-year warranty and global shipping – contact us for a density TCO comparison.
Detail: the same iBMC and FusionDirector management stack runs across the FusionServer portfolio – the 2488H V7, 2288H V7 and 5288 V7 are managed identically, so a 4-socket node does not introduce a second operations skill set.
