The Single-Socket Math Most Virtualization Teams Miss
Ask most architects how to add 160 cores to a rack and they will spec a dual-socket build – two CPUs, two sockets of licensing, twice the power draw. The Dell PowerEdge R7715 exists to challenge that default: one 5th Generation AMD EPYC 9005 processor with up to 160 cores in a single socket, 24 DDR5 slots, dual OCP networking and up to 40 EDSFF E3.S drives in a 2U chassis. For virtualization and HCI estates, the R7715 delivers the density of a dual-socket node at single-socket licensing and power cost.
Single-Socket vs Traditional Dual-Socket
| Dimension | R7715 (single-socket) | Typical dual-socket 2U |
|---|---|---|
| CPU cores | يصل إلى 160 (1 x EPYC 9005) | يصل إلى 128 (2 x 64-core) |
| CPU licensing | 1 socket | 2 sockets |
| ذاكرة | 24 x DDR5, يصل إلى 6 تيرابايت | 32 x DDR5 |
| فتحات PCIE GEN5 | يصل إلى 8 | يصل إلى 8 |
| OCP NIC slots | 2 x OCP 3.0 | 1-2 x OCP 3.0 |
| قوة & heat | One socket to feed and cool | Two sockets |
Per-core licensing for hypervisors like VMware is the sleeper cost in every virtualization refresh – the R7715 halves that line item while keeping the core count, which is exactly why Dell positions it for “virtualization with lower licensing costs” and hyper-converged infrastructure.
AMD EPYC 9005 Platform
The 5th Generation AMD EPYC 9005 Series brings up to 160 cores per processor with DDR5 support at up to 5200 MT/s across 24 registered ECC DIMM slots (6 السل ماكس). AMD’s platform security is built in: Secure Encrypted Virtualization (سيف) isolates VMs from the hypervisor, و Secure Memory Encryption (الشركات الصغيرة والمتوسطة) encrypts memory in place – both especially valuable in multi-tenant virtualization and HCI clusters.
تخزين & غارة
Drive-bay flexibility is a headline feature: 2 x U.2, 12 x 3.5 بوصة SAS/SATA, 8/16/24 × 2.5 بوصة SAS/SATA, 16 x 2.5-inch SSD + 8 x U.2 NVMe, و 8/16/32/40 x edsff e3.s layouts – the E3.S Gen5 path is the future-proofing play for high-density NVMe. RAID is handled by PERC H365i, H965i or H975i with BOSS-N1 (DC-MHS) hardware-RAID M.2 boot and an external HBA465e for JBOD expansion.
شبكة & توسيع PCIE
Two OCP NIC 3.0 فتحات (Gen5 x16 each) support 1GbE through 400GbE, and the AIC NIC options extend to 100/400GbE, NDR VPI and Fibre Channel 32/64. For smartNIC architectures, the R7715 offers NVIDIA BlueField-3 DPU options (2 x 200GbE or 1 x 400GbE) for offloaded networking and security. Eight x16 Gen5 PCIe slots (ارتفاع كامل, low-profile and dual-width full-length) handle GPU, HCA and storage cards with room to spare.
حماية & إدارة
حماية. Beyond AMD SEV/SME: silicon root of trust, التمهيد الآمن, cryptographically signed firmware, Secured Component Verification, Secure Erase, System Lockdown, chassis intrusion detection, Data at Rest Encryption (SEDs) and TPM 2.0 (FIPS/CC-TCG certified) – a zero-trust-ready posture from supply chain to retirement.
إدارة. The R7715 ships with the newest generation controller, iDRAC 10, including iDRAC Direct, Redfish RESTful API and Racadm CLI, plus Quick Sync 2 الوحدة اللاسلكية. OpenManage Enterprise (أووم) adds Power Manager, خدمات, Update Manager and APEX AIOps Observability, with integrations for VMware vCenter, Microsoft System Center, Ansible Collections and Terraform; change management runs through Dell Repository Manager, System Update and the Server Update Utility.
