HPE 458243-001 ProLiant ML350 G5 5U Rack Server

Overview

The HPE 458243-001 is a 5U rack-mount server built around the Intel Xeon E5420 quad-core processor running at 2.50GHz with an 80W TDP, a 1333MHz front-side bus, and 12MB of L2 cache. This is the ProLiant ML350 G5 platform in rack configuration — a generation-5 dual-processor-capable tower/rack design that was widely deployed in enterprise data centers, security back-end infrastructure, and branch office server rooms. At 70 lb and occupying 5U of rack space (35 × 24 × 17 in), plan for a dedicated mid-depth rack with appropriate rail support and adequate vertical clearance for adjacent equipment. The 458243-001 (often searched as 458243 001) is a factory-configured unit sourced from distribution; confirm target rack depth and rail kit compatibility before ordering.

Key Features

• Intel Xeon E5420 at 2.50GHz: The quad-core Harpertown die with 12MB L2 cache gives this platform genuine multi-threaded capacity for concurrent workloads — relevant if you are deploying it as a recording server, a VMS back-end, or a virtualization host handling multiple services simultaneously.
• 80W processor TDP: At 80W the E5420 sits at the lower end of the Xeon 5400 series power envelope, which matters in dense rack deployments where per-U wattage drives cooling and PDU circuit planning.
• 5U rack form factor (35 × 24 × 17 in): Five rack units is substantial — confirm your rack has at least 5U of open space and that the 35-inch depth fits within your cabinet's usable depth minus cable management.
• 1333MHz FSB: The 1333MHz front-side bus keeps memory throughput competitive for the platform generation, supporting adequate bandwidth for storage-intensive applications like continuous video recording.
• 70 lb chassis weight: This is a two-person lift. Factor rail kit load ratings and verify that floor-mounted racks meet weight capacity before final positioning.

Integration & Compatibility

As a ProLiant G5 platform, the 458243-001 is compatible with HP/HPE SmartStart provisioning tools and the iLO 2 remote management interface, enabling out-of-band access for headless deployments — useful in locked server rooms or remote branch sites. Confirm OS support with your specific workload; this platform predates Windows Server 2019 and later Linux kernels may require legacy driver attention. For rack servers pairing with network video infrastructure, verify VMS vendor support matrices for the installed OS version. Explore the broader HPE server and infrastructure catalog for complementary platforms. For storage-heavy video recording builds, review our network video recorder options or dedicated NVR appliances that may better fit a purpose-built surveillance back-end. If adding network infrastructure alongside this server, our PoE and managed switch selection supports the surrounding IP camera layer.

Frequently Asked Questions

Q: What processor does the HPE 458243-001 include?

A: The 458243-001 ships with an Intel Xeon E5420 quad-core processor running at 2.50GHz, with an 80W TDP, a 1333MHz front-side bus, and 12MB of L2 cache.

Q: What is the form factor and physical size of the 458243-001?

A: It is a 5U rack-mount unit measuring 35 × 24 × 17 inches (L × W × H) and weighing 70 lb. Verify rack depth and rail kit compatibility before installation.

Q: Does this server include rail kits or mounting hardware?

A: Package contents are not confirmed in available evidence. Contact the seller to verify whether rail kits are included or must be ordered separately.

Q: Is the HPE 458243-001 suitable as a VMS recording server?

A: The Xeon E5420 platform can handle multi-stream recording workloads, but suitability depends on VMS version OS requirements, available RAM, and storage configuration — none of which are confirmed in the current evidence. Verify with your VMS vendor's hardware compatibility list.

Q: What remote management capability does this platform support?

A: The ProLiant ML350 G5 generation supports HPE iLO 2 (Integrated Lights-Out 2) for out-of-band remote management, useful for headless or remote-site deployments.

The HPE 458243-001 is a ProLiant ML350 G5 in rack configuration — a platform I've seen deployed as a secondary recording server or a lightweight virtualization host in mid-size security back-ends. The Intel Xeon E5420 at 2.50GHz with 12MB L2 cache is the defining spec here: quad-core Harpertown with genuine multi-threaded headroom, which held up well in concurrent-stream scenarios when paired with adequate RAM and storage (neither confirmed in the available data for this SKU).

Technical Highlights:

• Xeon E5420 / 80W TDP: At 80W this processor draws less than the top-bin 5400-series parts — meaningful in a rack where you may be running multiple 5U units on a shared 20A circuit.
• 5U / 70 lb chassis: The 35-inch depth is on the longer side; compact 2-post or shallow 4-post racks will not accommodate this without an extender shelf or a full-depth cabinet.
• 1333MHz FSB: Paired with FB-DIMM DDR2 (the G5 memory type), the 1333MHz bus sustains the bandwidth needed for storage-intensive tasks like multi-camera continuous recording — but confirm installed RAM before sizing workloads.

Deployment Considerations:

• This is a two-person lift at 70 lb — coordinate rack installation with a second technician and confirm rail kit load ratings match the chassis weight before sliding it into position.
• The G5 platform predates current OS generations; if you are deploying a modern Linux distribution or Windows Server 2022, verify driver availability for the onboard NIC, RAID controller, and iLO 2 management interface before committing to this unit in a production role.

The 458243-001 fits best as a secondary or redundant compute node in an established ProLiant G5 environment — a shop already running this generation's tooling and driver stack, where adding a like-for-like unit is faster than replatforming. For greenfield deployments, evaluate current-generation HPE platforms instead.
