Use the Pro Disk Network Systems Compatibility tool at prodisknetwork.com/systems to browse by server model. For example, HP ProLiant DL380 Gen10 supports DDR4 ECC RDIMM at 2666/2933 MHz in slots 1–24. Each product page lists compatible server models. You can also email sales@prodisknetwork.com with your server model and we will confirm compatibility.

SAS (Serial Attached SCSI) drives are enterprise-grade with dual-port redundancy, 10K or 15K RPM speeds, 2.4 million hour MTBF, and up to 12Gbps throughput — designed for 24/7 server operation. SATA drives are lower cost, 7200 RPM, single-port, and suitable for nearline storage or desktop use. Enterprise servers typically use SAS for performance and NL-SAS/SATA for capacity.

An SFP (Small Form-factor Pluggable) transceiver converts electrical signals to optical fiber signals in network switches and routers. Choose based on: speed (1G SFP, 10G SFP+, 25G SFP28, 40G QSFP+), distance (SR = short range up to 300m multimode, LR = long range up to 10km single-mode), and switch brand compatibility (Cisco, Aruba, Juniper). Pro Disk Network stocks compatible transceivers for all major switch brands at 60-80% below OEM pricing.

ECC (Error-Correcting Code) RAM detects and corrects single-bit memory errors in real time, preventing data corruption and system crashes. All enterprise servers require ECC registered (RDIMM) or load-reduced (LRDIMM) memory. Standard desktop DDR4/DDR5 is non-ECC and will not work in servers. Pro Disk Network stocks 91,000+ ECC memory modules for all major server platforms.

NVMe (Non-Volatile Memory Express) is a protocol for SSDs that connects over PCIe, delivering 5–7 GB/s sequential read speeds versus 500–600 MB/s for SATA SSDs. NVMe drives use M.2 2280, U.2, or AIC form factors. For enterprise workloads requiring low latency (databases, VMs, AI inference), NVMe is the standard. SATA SSDs are still used for boot drives and cost-sensitive capacity storage.

A RAID controller manages multiple physical drives as a single logical volume for redundancy and/or performance. Dell servers use PERC controllers (H310 for JBOD/passthrough, H710/H730 for RAID 0/1/5/6/10). HPE servers use Smart Array controllers (P408i, P816i). If you run VMware, Proxmox, TrueNAS, or Windows Server with multiple drives, a RAID controller is recommended. For ZFS-based storage, use the H310 in IT (passthrough) mode so ZFS has direct drive access.

iDRAC (Dell) and iLO (HPE) are out-of-band remote management controllers embedded in enterprise servers. They give you remote power cycling, virtual KVM console, virtual media (ISO mount), hardware health alerts, and system event logs — all without physical access. iDRAC 9 (Dell Gen14-16) and iLO 5/6 (HPE Gen10/Gen11) are the current versions. Pro Disk Network stocks iDRAC and iLO expansion cards for servers missing the Enterprise license.

A hot-swap drive bay lets you insert or remove a drive while the server is powered on and running — no shutdown required. Enterprise servers (HP ProLiant, Dell PowerEdge) have hot-swap bays as standard. Drives sit in metal caddies (trays) that click into the bay. Hot-swap requires a compatible hot-swap drive caddy — caddies are generation and form-factor specific (2.5" SFF vs 3.5" LFF).

DDR4 runs at 2133–3200 MHz and is used in Gen9–Gen10+ servers (Xeon E5, Scalable Gen1-Gen3). DDR5 runs at 4800–5600 MHz with higher per-channel bandwidth and is used in Gen11 servers (Xeon 4th/5th Gen, AMD EPYC Genoa). DDR5 offers 1.5–2× bandwidth improvement for memory-intensive workloads like databases and AI inference. DDR4 and DDR5 DIMMs are NOT interchangeable — slot keys are physically different. Check your server generation before ordering.

Match three criteria: (1) Speed — 1G (SFP), 10G (SFP+), 25G (SFP28), 40G (QSFP+), 100G (QSFP28); (2) Distance — SR (short range, multimode fiber, ≤300m), LR (long range, single-mode, ≤10km), DAC (copper twinax, ≤10m, lowest cost); (3) Switch brand — Cisco, Aruba, Juniper each have OEM modules but all support compatible (third-party) transceivers. On Cisco, run "service unsupported-transceiver" to allow non-Cisco modules. Pro Disk Network compatible transceivers are 60–80% cheaper than OEM and fully tested.

Visit prodisknetwork.com/systems and filter by server model (e.g., HP ProLiant DL380 Gen10). You can browse compatible RAM, drives, PSU, rail kits, and accessories with confirmed compatibility. For the DL380 Gen10: max 768GB DDR4 RDIMM across 24 slots; PSU is 500W or 800W Flex Slot; drives are 2.5" SFF hot-swap SAS/SATA/NVMe. Email sales@prodisknetwork.com with your server serial number for guaranteed compatibility confirmation.

Visit prodisknetwork.com/systems and select your PowerEdge model. For the R720 (Gen12): max 768GB DDR3 RDIMM across 24 slots; 495W or 750W hot-swap PSU; PERC H310/H710/H710P RAID controller; 2.5" SFF or 3.5" LFF hot-swap bays. For the R740 (Gen14): DDR4 RDIMM up to 3TB; 750W or 1100W PSU; PERC H730P or H740P; up to 8× 2.5" or 4× 3.5" front bays. Always check the iDRAC generation matches your server.

No — drive caddies are generation and form-factor specific. A Dell Gen12 (R720) SFF caddy will not fit a Gen14 (R740) without modification, and vice versa. Key differences are the latch mechanism, backplane connector position, and slide geometry. Always order the caddy for your exact server model. Pro Disk Network product pages list exact compatible server models for every caddy.

You can mix capacities in most enterprise servers, but you should follow the manufacturer's memory population rules to avoid performance degradation. Best practice: populate in matched pairs (or sets of 4 on quad-channel Xeon), start from the slots specified in the QuickSpecs, and use identical speed DIMMs. Mixing speeds causes all DIMMs to run at the slowest speed. For maximum performance, use identical DIMMs in all slots of the same memory channel.

Yes. Pro Disk Network stocks NVIDIA A100 (40GB/80GB), A30, A10, H100 80GB, Tesla T4, and V100 GPU accelerators for enterprise AI/ML and HPC workloads. We also carry full GPU-configured rack servers from HP and Dell with multiple GPU slots. Search "A100", "H100", "Tesla", or "GPU" on prodisknetwork.com, or email sales@prodisknetwork.com for a GPU server quote.

HP ProLiant DL380 Gen10: 3TB (24× 128GB LRDIMM). Dell PowerEdge R740: 3TB (24× 128GB LRDIMM). Dell PowerEdge R720: 768GB (24× 32GB RDIMM DDR3). HP ProLiant DL380 Gen11: 8TB (24× DDR5 RDIMM). Cisco UCS C240 M5: 3TB (24 slots). Lenovo ThinkSystem SR650 Gen2: 6TB (32 slots). Actual max depends on CPU installed — higher-tier Xeon CPUs support more memory channels.
