델 파워엣지 R860 | 4S SAP HANA & 16TB DDR5 Server

Four Sockets in 2U: Why the R860 Exists

The PowerEdge R860 answers a specific question: what do you do when two sockets cannot hold the working set? SAP HANA scale-up, large in-memory analytics and consolidated 4-socket databases need more memory than any 2-socket node can carry – and the R860 delivers up to 16TB of DDR5 in a standard 2U chassis, replacing the older R840 with a Gen5-era platform.

Platform Overview

Config Calculator: SAP HANA Memory Sizing

1. Working set: sum of hot data + column-store + delta + 20% headroom. A 4TB HANA database with 1:2 compression needs roughly 2.2-2.5TB of server memory.
2. DIMM plan: 64 슬롯. 1 DPC runs 4800 MT/s but caps capacity; 2 DPC reaches 16TB at 4400 MT/s. For HANA, capacity beats peak speed – run 2 DPC with 256GB RDIMMs (8TB class) or 512GB (16TB class) if the budget allows.
3. Verify NUMA: four sockets mean four NUMA domains; pin HANA instances and their memory pools per socket to avoid cross-socket traffic.
4. Boot and log: 보스 -N1 (2x M.2 NVMe RAID1) for boot, E3.S Gen5 NVMe for HANA data/log/backup volumes.

R840 to R860 Migration

The migration path is export-backup-restore: back up HANA at the storage layer, restore onto the R860’s NVMe, then re-point the scale-up licenses. Expect materially faster column scans on Gen5 NVMe and DDR5 bandwidth.

Procurement Traps on 4-Socket Servers

• License math: SAP HANA is licensed per GB of memory – a 16TB R860 costs far more in license than hardware. Size the DB, then size the box, not the reverse.
• Memory topology: verify 1 DPC vs 2 DPC speeds in the quote; vendors quoting 4800 MT/s on a full 16TB build are not reading the spec sheet.
• 후면 베이: 24x 2.5-inch front config leaves rear room for 2x 2.5-inch or 4x E3.S – confirm the backplane SKU matches your boot/NVMe plan.
• PSU class: 4x 350W CPUs plus 24 drives can exceed 2kW; order 2400W Platinum pair, not 1100W.
• Rack depth: 869.2mm is long for standard 800mm cabinets – verify cable management arms and rail fit.

Workload Fit

• SAP HANA scale-up: the primary design point – 우리를 보아라 SAP HANA deployment guide for R960/R860 sizing.
• Large in-memory analytics: 64 DDR5 slots beat any 2-socket node for column-store analytics.
• Consolidated databases: run multiple mission databases with resource isolation on one 4-socket host instead of several 2-socket boxes.
• VDI and desktop virtualization: high-core-count 4S nodes sustain dense RDSH pools.

4-Socket Platform Matrix

Deployment Snapshot: In-Memory Analytics Consolidation

A regional bank consolidated six 2-socket analytics nodes into two R860s. The win was memory: 4.5TB of usable HANA working set across 128 DDR5 slots with room to grow, versus 2.4TB across the old fleet. Cross-socket NUMA pinning held column scans within socket-local memory, and the 8x E3.S Gen5 NVMe layout carried the data/log tier at Gen5 bandwidth. PDU power dropped from 8.2kW to 5.1kW after decommissioning the legacy nodes.

Ordering Checklist: What to Verify Before Signing

• Memory plan on paper: request the exact DIMM map (계급, DPC, speed per slot) – a 16TB quote at 4800 MT/s is a red flag unless it is 1 DPC.
• Backplane SKU: confirm front bay type (24x 2.5-inch vs 8x E3.S) and rear bay option (2x 2.5-inch or 4x E3.S) match the storage design.
• PERC class: H965i (내부) vs H965e (외부) – expansion enclosures need the ‘e’ variant with external ports.
• PSU and power cords: 2400W Platinum pair for 4x 350W CPU builds; verify C19-style cord/PDU compatibility at 200-240V.
• iDRAC licensing tier: confirm iDRAC9 Enterprise entitlement in the quote for telemetry and virtual media.
• Rack depth survey: measure rail-to-rail depth with cable arms; 869.2mm chassis needs a 1000mm+ cabinet or a rear offset kit.

Lifecycle and Support

The R860 is a 4th Gen Xeon Scalable platform with a long support tail: Dell keeps firmware, driver and OS certification matrices current through the platform’s standard lifecycle, and iDRAC9 telemetry feeds OpenManage Enterprise for proactive alerting. For mission databases, pair the platform with Dell ProSupport Plus or a partner-managed 3-year warranty plan – our standard quote includes 3-year warranty, 공장 직접 가격, 글로벌 배송 및 무료 구성 상담, with optional on-site NBD for production HANA nodes. Spares strategy: keep one 2400W PSU, one PERC H965i and one E3.S boot drive on the shelf per cluster to cut MTTR to minutes.
