USING HARDWARE RESPONSIBLY

Maintain, redeploy or replace

Consider repairability, remaining support and actual operating demand. Extending service life is useful only when the equipment still meets your security and reliability requirements.

MaintainCheck parts, firmware and service options.

RedeployMatch a suitable role and securely erase any retained data.

Retire responsiblyUse documented data removal and an appropriate electronics recycler.

Compare operating energy

Use measured average input power for the same workload. PSU ratings and processor TDP are different from total system power.

Current equipment · WProposed equipment · WHours per yearNumber of units

Enter valid measurements to compareEnergy difference = (current W − proposed W) × hours × units ÷ 1,000. Excludes cooling, embodied emissions and purchase costs.

CONNECTION DETAILS

Network and storage connections

Platform Selection

Chassis revision, regional SKU and current sales and support status are confirmed before parts are selected.

Compute and memory

Processor family, socket count, thermal limits and memory population are checked together for the selected platform.

Storage and data path

Drive media, form factor, backplane, controller or HBA, cabling and boot design are reviewed together.

I/O and lifecycle

NICs, accelerators, risers, power, firmware, rails, support and regional accessories are listed separately in the BOM.

Configuration Overview

Complete systems and spare parts are quoted separately. CPUs, DIMMs, drive carriers, controllers, NICs and PSUs are matched to the selected platform unless an approved compatible alternative is listed in the quotation.

Servers, switches and storage to consider together

Star Networking reviews upstream switching, storage path, OOB management, power input, rails and service details together so the delivered node can be installed without reworking the BOM.

01
Upstream fabric
25/100/400G uplinks, DAC/AOC, optics and OOB management are planned before shipment.
02
Server node
Supermicro ARS-421GL-NR is staged with CPU, DIMM, storage, controller, NIC, PSU and firmware profile.
03
Storage tier
Boot media, hot data tier, capacity tier and backup path are separated in the BOM.
04
Order Documentation
Service terms, serial numbers, labels, packing details and delivery milestones are recorded with the order.

Deployment / workload

Choosing a server for your applications

Choose platform options and confirm the operating environment before finalizing the design.

Virtualization and private cloud

Balance core density, memory capacity, boot resilience, east-west traffic and support policy.

Data and application services

Align memory, storage latency, controller mode and network throughput with the application profile.

Infrastructure services

Plan resilient boot, management access, power redundancy and a repeatable firmware baseline.

Scale-out deployments

Standardize node BOMs, spares, firmware and delivery batches before multi-system rollout.
