HCI-CPU-A9254 개요

The Cisco HCI-CPU-A9254 is a server processor upgrade module based on the AMD EPYC 9254, a 4th-generation EPYC 9004-series CPU with 24 cores, a 2.9 GHz base clock, 128 MB of L3 cache, a 200 W thermal design power, and support for DDR5 memory at 4800 MT/s. The processor is packaged for Cisco UCS and Hyperconverged Infrastructure (HCI) server platforms using the Socket SP5 (LGA-6096) land grid array interface.

A server processor (CPU) is the central compute engine of a data center server, sitting at the top of the compute hierarchy: microprocessor -> multi-core server processor -> server platform -> data center infrastructure. The EPYC 9004 family, codenamed Genoa, uses AMD's Zen 4 core architecture on a 5 nm process with a chiplet design in which up to 12 core-complex dies connect to a single I/O die via AMD Infinity Fabric.

Key features of the EPYC 9254 include 24 Zen 4 cores with simultaneous multithreading for 48 threads, a large 128 MB shared L3 cache, PCIe Gen5 connectivity for high-bandwidth accelerators and NVMe storage, and DDR5-4800 memory support delivering dramatically higher bandwidth than the prior DDR4 generation. The 200 W default TDP offers a balanced performance-per-watt profile for dense virtualization workloads.

In the Cisco HCI variant, the processor is validated and supported for Cisco Hyperconverged Infrastructure nodes, where compute, storage, and networking are consolidated on one platform. Typical applications include virtualization clusters, private cloud, software-defined storage, database servers, and data analytics. According to AMD, the EPYC 9004 series targets modern data centers requiring exceptional time-to-results and energy efficiency.

Design and integration considerations: verify Socket SP5 motherboard support, BIOS/firmware qualification in the Cisco UCS Hardware Compatibility List, adequate VRM delivery for the 200 W TDP, and high-performance cooling. Memory channel population should follow the vendor configuration guide to achieve full DDR5-4800 bandwidth.

This page synthesizes distributor pricing, Cisco family cross-references (UCS-CPU-A9254, HCIX-CPU-A9254), and integration guidance not found in a single datasheet, providing engineers and buyers with one consolidated, verifiable reference.

🖥️

Hyperconverged Infrastructure (HCI) Nodes

The HCI-CPU-A9254 is purpose-qualified for Cisco Hyperconverged Infrastructure nodes, where compute, software-defined storage, and virtual networking run on one server platform. The 24 Zen 4 cores at 2.9 GHz give per-VM clock headroom, while 128 MB of L3 cache reduces latency for storage I/O stacks that are cache-heavy. DDR5-4800 memory support is critical in HCI because the distributed storage layer consumes significant memory bandwidth for caching and erasure-coding operations. Deployed per node with the platform's qualified DIMM population, the 200 W TDP allows denser node counts per rack than 300-360 W class SKUs, improving performance-per-watt in scale-out HCI clusters. Validate BIOS and driver qualification in the Cisco UCS HCL before production rollout.

⚙️

Server Virtualization Clusters

For VMware, Hyper-V, or KVM virtualization farms, the EPYC 9254's 24 cores and 48 threads provide a high VM-density per socket, and the 2.9 GHz base clock sustains clock-sensitive guest workloads better than lower-clock, higher-core-count SKUs. The chiplet-based Zen 4 architecture connects up to 12 core-complex dies via AMD Infinity Fabric, and the 128 MB shared L3 cache benefits co-scheduled vCPU workloads. DDR5-4800 support raises memory bandwidth per core versus DDR4-generation hosts, reducing NUMA-related stalls during live migration and memory ballooning. At a 200 W TDP, rack power budgets stretch further, letting operators add nodes under fixed power caps. Follow the memory population guide to activate all channels at full 4800 MT/s speed for maximum consolidation ratios.

Software-Defined Storage

Software-defined storage platforms (Ceph, vSAN, storage services in HCI stacks) are CPU- and memory-bandwidth-hungry due to replication, checksumming, compression, and erasure coding. The EPYC 9254's 24 cores at 2.9 GHz handle these background operations while leaving capacity for guest I/O, and its 128 MB L3 cache buffers metadata-intensive workloads. DDR5-4800 memory is a major advantage: the storage data path uses large write caches whose throughput scales directly with memory bandwidth. AMD positions the 9004 series for modern data centers needing energy efficiency, and at 200 W TDP this SKU delivers storage throughput per watt suited to dense storage clusters. Size NIC bandwidth (PCIe Gen5 attached) to avoid saturating the fabric during rebuild operations.

Database Servers

Transactional databases such as PostgreSQL, MySQL, and SQL Server reward high per-core clocks and large cache capacity, both strengths of the EPYC 9254: 2.9 GHz base clock with Zen 4 IPC and 128 MB of shared L3 cache keep hot index pages and query plans close to the cores. DDR5-4800 support feeds the buffer pool at higher bandwidth than DDR4-3200 platforms, reducing latency on memory-bound scans. With 48 threads from 24 cores, the CPU handles high connection counts with fewer context switches. The 200 W TDP keeps thermal design straightforward in 1U/2U chassis, allowing higher database node density per rack. Estimated: DDR5-4800 across all channels provides roughly 50% more theoretical bandwidth per channel than DDR4-3200, directly benefiting OLTP buffer-pool hit rates.

Private Cloud and Data Analytics

Private cloud controllers and analytics frameworks (Spark, Kafka, ELK) benefit from the EPYC 9254's balanced profile: enough cores (24) for parallel ingestion and query execution, and a 2.9 GHz clock that keeps latency-sensitive control planes responsive. The 128 MB L3 cache supports data shuffling stages common in analytics pipelines, and DDR5-4800 bandwidth accelerates in-memory processing frames where datasets approach RAM capacity. AMD's 9004-series chiplet design lets this SKU share platform validation, tooling, and BIOS images with higher-core SKUs, simplifying mixed-cluster operations. At 200 W, cluster operators gain predictable thermal behavior in dense compute pods, and PCIe Gen5 I/O bandwidth supports modern 200G-class networking and NVMe acceleration without bottlenecking the CPU.

Enterprise Server Refresh / Upgrades

Organizations refreshing older DDR4-era servers (EPYC 7002/7003 or Xeon Scalable first/second generation) can use the HCI-CPU-A9254 to move to the Zen 4 / DDR5 / PCIe Gen5 platform in a single step. Per AMD's product positioning, the 9004 series targets modern data centers needing better time-to-results and energy efficiency: the jump to DDR5-4800 raises memory bandwidth, and PCIe Gen5 doubles I/O bandwidth per lane versus Gen3-era hosts. Because this Cisco part number is a qualified option for Cisco UCS/HCI chassis, refresh projects can retain existing management tooling and support contracts. Confirm chassis generation support and minimum BIOS version in the Cisco UCS Hardware Compatibility List before ordering, since SP5 CPUs are not backward-compatible with SP3 sockets.

The HCI-CPU-A9254, HCIX-CPU-A9254, and UCS-CPU-A9254 are all Cisco part numbers for the same underlying AMD EPYC 9254 processor: 24 cores, 2.9 GHz, 128 MB cache, 200 W, DDR5-4800. The prefixes indicate the Cisco program or bundle the part ships with (HCI/HCIX hyperconverged configurations versus standard UCS processor-only option). Verify chassis and firmware support with your Cisco representative.
What is the difference between EPYC 9254 and Intel Xeon Gold 6430?
The AMD EPYC 9254 has 24 Zen 4 cores at 2.9 GHz with 128 MB L3 cache and a 200 W TDP, while the Intel Xeon Gold 6430 has 32 cores at a 2.1 GHz base clock. According to TopCPU's comparison, the EPYC 9254 generally offers higher per-core clocks and Zen 4 IPC, making it stronger for clock-sensitive workloads, whereas the Xeon offers more cores at lower frequency for highly parallel throughput tasks.
Which memory does the EPYC 9254 support?
The AMD EPYC 9254 supports DDR5 memory at 4800 MT/s, as specified in the Cisco product description (HCIX-CPU-A9254: 24C/128MB cache, DDR5 4800MT/s). For full bandwidth, populate all memory channels per the server vendor's population rules; using lower-speed DIMMs will reduce memory throughput. RDIMM/3DS RDIMM capacity limits should be confirmed against the specific Cisco server platform documentation.
What is the best drop-in replacement for HCI-CPU-A9254?
The best drop-in replacement is the Cisco UCS-CPU-A9254 or HCIX-CPU-A9254, which are the same AMD EPYC 9254 silicon (24 cores, 2.9 GHz, 128 MB L3, 200 W, Socket SP5) under different Cisco program part numbers. Outside the Cisco ecosystem, the AMD EPYC 9254 processor sold for HPE platforms is the identical CPU die but should only be used if your board vendor qualifies HPE-sourced parts.
Can EPYC 9254 replace Xeon in an existing server?
No. The AMD EPYC 9254 uses Socket SP5 and requires an SP5-compatible motherboard, BIOS, and VRM design; it cannot replace an Intel Xeon processor in an existing Socket E server. If migrating from Xeon to EPYC 9004, plan a full platform change including DDR5 memory configuration and cooling, and validate against the Cisco UCS Hardware Compatibility List or your board vendor's qualified processor list.
Is HCI-CPU-A9254 in stock and what is the lead time?
Availability varies by channel. posglobal.com lists the equivalent UCS-CPU-A9254 as dropship/preorder at USD 4,782.55, while serversupply.com lists the same processor as in stock as a brand-new unit. Lead time therefore ranges from immediate shipment to several weeks depending on the distributor and condition. Contact multiple distributors for the shortest confirmed lead time as of October 2026.
Where to download the HCI-CPU-A9254 datasheet PDF?
There is no single Cisco-branded PDF for this part; the authoritative product specification is AMD's EPYC 9254 product page at amd.com (EPYC 9004 series), which lists cores, clocks, cache, TDP, and memory support. For platform-level details, consult the HPE/AMD digital data sheet (PSN1014690633PREN documents the same EPYC 9254 CPU) and the Cisco UCS Hardware Compatibility List for qualified server configurations.
How many cores and how much cache does the EPYC 9254 have?
The AMD EPYC 9254 has 24 cores and 128 MB of L3 cache, running at a 2.9 GHz base clock with a 200 W TDP. This is confirmed by multiple independent distributor listings (Aztek Computers, Memory4Less, Zoro) describing it as 'AMD 9254 2.9GHz 200W 24C/128MB CACHE DDR5 4800MT/S'. With simultaneous multithreading, the processor runs 48 threads for heavily virtualized workloads.
What cooling does a 200W EPYC 9254 require?
The 200 W TDP of the EPYC 9254 requires a server-class passive heatsink and chassis airflow designed for Socket SP5 200 W-class processors. In Cisco UCS/HCI nodes, use only Cisco-qualified heatsink and fan options so thermal telemetry and fan control remain supported. Estimated: at 200 W dissipation, even an efficient 0.15 C/W heatsink-to-ambient solution yields roughly a 30 C rise over inlet temperature, so data center inlet temperatures must stay within the server's specified limits.
When should I choose the EPYC 9254 over the EPYC 9354 or 9554?
Choose the EPYC 9254 when you need a strong balance of 24 high-clock Zen 4 cores at 2.9 GHz with a moderate 200 W TDP for virtualization, databases, and HCI nodes. Step up to higher 9004-series models only if you need more than 24 cores or larger L3 cache, accepting higher TDP and cost. For power-constrained or cost-sensitive clusters, the 9254's 200 W envelope and 128 MB cache make it a sweet-spot choice per AMD's 9004-series positioning.
Does the HCI-CPU-A9254 support PCIe Gen5?
Yes. The EPYC 9004 (Genoa) platform architecture integrates PCIe Gen5 controllers via the I/O die, providing substantially higher bandwidth to NVMe storage and accelerators than PCIe Gen4 platforms. However, the exact lane count allocation in a Cisco HCI node depends on the server platform and configuration, so confirm lane bifurcation and slot mapping against the Cisco platform specification before designing high-bandwidth add-in card deployments.
What are the key specifications of HCI-CPU-A9254 that engineers should know?
Key specifications: 24 Zen 4 cores at 2.9 GHz base clock; 128 MB L3 cache; 200 W TDP; DDR5-4800 MT/s memory support; Socket SP5 installation; Cisco HCI/UCS platform qualification. Per distributor listings (Aztek, Memory4Less), the part is 'AMD 9254 2.9GHZ 200W 24C/128MB CACHE DDR5 4800MT/S'. It belongs to AMD's 4th-generation EPYC 9004 series for modern data centers, with a reference distributor price of about USD 4,782.55 as of October 2026.

선택 가이드

Choose the HCI-CPU-A9254 when you are deploying or expanding Cisco Hyperconverged Infrastructure nodes and need a balanced 24-core, 2.9 GHz, 200 W CPU with DDR5-4800 support. Choose the UCS-CPU-A9254 (same silicon, standard UCS program) if your deployment is a conventional UCS server rather than an HCI bundle - pricing and channel availability may differ. Choose the HCIX-CPU-A9254 when your reseller stocks that program code at better terms; it is electrically identical. Outside the Cisco ecosystem, use an AMD/HPE-channel EPYC 9254 only on a platform that qualifies that sourcing. If your workloads need more than 24 cores or larger cache, step up within the EPYC 9004 family instead; if you need maximum core count at lower clock, the Intel Xeon Gold 6430 (32C/2.1 GHz) is the cross-brand alternative. All choices require Socket SP5 platforms - none are drop-in for older SP3 or Xeon sockets.

주요 차별점

  • HCI-program qualification (vs UCS-CPU-A9254)
  • Higher per-core clocks than Xeon Gold 6430 (vs Intel Xeon Gold 6430)
  • DDR5-4800 memory bandwidth (vs Previous-generation EPYC (Milan, DDR4-3200))

설계 노트

The EPYC 9254 has a 200 W TDP, so the host board must provide an SP5 VRM rated for 200 W-class processors with proper power-stage cooling. Estimated: at full load and a typical 90% VRM efficiency, input power draw is roughly 222 W per socket plus memory and fans; size PSU headroom and facility circuits accordingly. Use only Cisco-qualified power options in HCI chassis so telemetry and redundant-power policies remain supported.

Select a server-class passive heatsink validated for 200 W Socket SP5 processors and confirm chassis airflow meets the Cisco thermal specification for the target ambient temperature. Estimated: a heatsink solution with 0.15 C/W thermal resistance yields about a 30 C rise over inlet at 200 W, so a 35 C inlet implies roughly a 65 C package temperature before contribution from VRM and memory heating. Undersized cooling will trigger thermal throttling and reduce sustained clock rates.

Socket SP5 (Genoa) processors are not compatible with SP3 (Naples/Rome/Milan) sockets - a platform change is required when migrating from older EPYC generations. Before ordering, verify the exact chassis generation, minimum BIOS/firmware version, and heatsink option in the Cisco UCS Hardware Compatibility List (ucshcltool.cloudapps.cisco.com). Mixing HPE-channel EPYC 9254 parts into Cisco chassis is not supported and may void warranty and firmware entitlement.
