866530-L21 HPE ML350 Gen10 Intel Xeon Silver 4114 2.2GHz 10 Core 85W FIO Processor.

Key technical attributes and why they matter

Processor characteristics: Intel Xeon Silver 4114 (2.2GHz, 10-core)

The Intel Xeon Silver 4114 is a mid-range data center CPU designed for balanced throughput and energy efficiency. In the context of the HPE ML350 Gen10, the 4114's 10 physical cores and 2.2GHz base clock provide meaningful multi-threaded performance for multi-VM and database-lighter workloads while its 85W thermal design power (TDP) keeps power draw and cooling requirements moderate. This balance is especially valuable in tower servers deployed in offices, branch sites, and edge compute locations where acoustic and thermal constraints matter.

What the core count and clock speed mean

• 10 cores: Enables concurrent processing of multiple threads — improves virtualization density and parallel database query handling.
• 2.2GHz base frequency: Stable per-core speed ideal for sustained server workloads without aggressive frequency-hopping.
• 85W TDP: Reasonable power envelope for tower and rack-convertible deployments, reducing cooling and UPS sizing complexity.

Platform: HPE ProLiant ML350 Gen10 chassis and system features

The ML350 Gen10 chassis offers expandability and resilience. Key platform-level features typically emphasized in this category include:

• Flexible storage bays supporting both SAS and SATA drives, plus NVMe options in certain configurations.
• HPE Smart Array controller compatibility for RAID configurations and data protection.
• Multiple memory channels and broad DIMM capacity for ECC RDIMM/LRDIMM memory, enabling higher memory footprints for in-memory databases and virtualization.
• PCIe expansion slots for network, storage, or accelerator cards (NICs, HBAs, GPUs, or FPGAs).
• Redundant power supply options (hot-plug, modular) for uptime-sensitive deployments.

Memory topology and scalability

Memory configuration in the ML350 Gen10 typically supports multiple channels per CPU; configuring matched DIMMs across channels yields optimal bandwidth. For users planning virtualization or in-memory caching, prioritizing higher-capacity RDIMMs and populating channels symmetrically will deliver better sustained throughput and lower memory latency.

Performance tuning and configuration tips

Optimizing for virtualization (VMware, Hyper-V, KVM)

• Allocate vCPUs conservatively — with 10 physical cores, plan vCPU assignments to avoid oversubscription in latency-sensitive workloads.
• Use SSDs or NVMe for VM datastore to improve I/O performance and reduce boot/response times.
• Enable large memory pages and NUMA-aware placement when running memory-intensive VMs to maximize throughput.

Database and transaction processing guidance

For OLTP and mid-sized database workloads:

• Favor higher memory allocations to database buffer pools before scaling CPU core counts.
• Implement RAID with battery-backed caching or NVMe caching layers to enhance write performance and durability.
• Consider separate storage tiering for logs and data to minimize I/O contention.

Tuning for compute-heavy applications

Applications that require sustained compute (batch jobs, analytics) will benefit from maximizing thermal headroom: choose power and cooling configurations that avoid thermal throttling under prolonged load. If workloads are highly parallel, adding a second CPU (if chassis supports dual-socket variants) or selecting higher-frequency Xeon processors may be more effective than aggressive core overcommitment.

Compatibility and expandability

Storage options and RAID choices

The ML350 Gen10 supports a wide range of storage media. Typical options include:

• Hot-plug SAS/SATA HDDs and SSDs for capacity and mixed workloads.
• NVMe drives for extreme low-latency storage (if chassis/rail supports NVMe trays).
• Hardware RAID controllers (HPE Smart Array) with cache modules for improved resilience and performance.

Network and I/O expansion

Network interfaces can be tailored to project needs — from 1GbE NICs for basic connectivity up to 10/25/40/100GbE cards for modern networking demands. PCIe expansion allows for additional storage controllers, GPU/accelerator cards for ML inference, or specialized NICs for SR-IOV and DPDK acceleration.

Choosing the right RAID level

• RAID 1/10: Best for high IOPS and redundancy for databases and VMs.
• RAID 5/6: Good read performance and higher usable capacity — consider rebuild times on large NL-SAS drives.
• Hardware RAID with battery-backed cache or flash-backed write cache: Enhances write performance while maintaining data safety.

Reliability, serviceability, and management

HPE management tools and lifecycle features

HPE ProLiant servers commonly include integrated management capabilities that ease deployment and maintenance. Relevant management features for this category include:

• iLO (Integrated Lights-Out): Remote server management for out-of-band access, firmware updates, and health monitoring.
• Scripting and automation: iLO RESTful API and HPE OneView integrations to automate provisioning and firmware baseline enforcement.
• Proactive Health Monitoring: Predictive alerts for failing components, enabling preemptive maintenance.

Serviceability: hot-swap and modular design

Hot-plug drive bays, modular PSUs, and accessible DIMM/CPU trays make on-site maintenance faster and less disruptive. For 24/7 operations, choose configurations with redundant power and hot-spare drives to minimize planned downtime.

Security features and firmware best practices

Built-in platform security

Security in enterprise servers spans firmware, hardware root of trust, and runtime protections. For this ML350 Gen10 category:

• Firmware integrity features help prevent unauthorized code execution at boot.
• Trusted Platform Modules (TPM) and secure boot capabilities support encrypted volumes and secure attestation.
• Regular firmware and BIOS updates should be part of baseline maintenance to close vulnerabilities.

Patch and firmware lifecycle

Establish a firmware update cadence aligned with vendor advisories. For production systems, test firmware updates in a staging environment first and then deploy using automated tooling (HPE Scripting Toolkit, OneView) to reduce human error.

Common use cases and deployment scenarios

Small-to-medium business (SMB) core server

For many SMBs, an ML350 Gen10 equipped with the Xeon Silver 4114 is an excellent general-purpose server for:

• File and print services with moderate concurrency.
• Domain controllers, DNS/DHCP services.
• Small virtualization clusters hosting 5–20 VMs depending on memory and storage choices.

Remote/branch office and edge compute

In branch offices, the ML350's tower footprint and quieter operation (relative to higher-TDP systems) combined with the Xeon Silver 4114's efficient performance make it suitable for local caching, application hosting, and localized data processing.

Database and application servers

Paired with fast storage and ample memory, this configuration supports transactional databases, middleware, and application stacks used by mid-market enterprises. Performance gains are most pronounced when storage I/O and memory are prioritized alongside CPU selection.

Virtualization and container platforms

The CPU core count and memory expandability make the ML350 Gen10 a good candidate for hyperconverged or small virtualization clusters. When running container orchestration platforms (Kubernetes, OpenShift), consider network and storage readiness for clustered storage backends.

Procurement considerations and SKU variations

New vs refurbished vs certified pre-owned

Buyers can choose between new OEM configurations, refurbished units, or certified pre-owned hardware. Key decision points include warranty coverage, support level, and total cost of ownership. Refurbished systems may offer cost savings but ensure updated firmware and verified component health before deployment.

Factory-configured SKUs and custom builds

HPE and authorized resellers typically offer factory-configured SKUs that bundle processors, memory, drive trays, and PSUs. Custom builds allow for precise tailoring to workload needs — for example, maximizing SSD capacity for storage-heavy workloads or adding acceleration cards for AI/ML inference.

Warranty and support tiers

• Basic warranty: Manufacturer defects and part replacements within a fixed term.
• ProSupport/Plus: Faster response times, on-site service, and higher SLAs for mission-critical deployments.
• Extended care: Optional coverage to match business continuity requirements.

Energy efficiency and thermal planning

Power budgeting and cooling

Because the Xeon Silver 4114 is rated at 85W TDP, power planning is simplified relative to higher-wattage CPUs. Still, total system power must account for drives, memory population, add-in cards, and peak utilization. When designing data closets or small server rooms, allocate adequate AC capacity and airflow to prevent hotspots and ensure acoustic comfort.

Sizing UPS and PDUs

Estimate peak draw (including redundant PSU overhead) when sizing UPS to ensure safe shutdowns during outages and to support graceful failover where needed. Use manufacturer power calculators or empirical measurements during pilot runs to refine sizing.

Migration, upgrades, and lifecycle planning

Scaling up vs scaling out

Decide whether to scale vertically (upgrading this server with more RAM, storage, or CPU in supported configurations) or scale horizontally (adding more ML350 nodes) based on application architecture and redundancy requirements. For stateless microservices, horizontal scaling may be cheaper and more resilient; for single-instance database servers, vertical scaling might be easier.
