Web Hosting & Application Servers

Web hosting / shared / VPS / managed-WordPress hosting providers operate at thin margins, so hardware choice directly impacts unit economics. The bottleneck is almost always I/O — page caches, database queries, and PHP-FPM child processes all hammer the storage subsystem.

Pro Disk Network's hosting-server kit list: Dell PowerEdge R650 (1U, 24 SFF) and R750 (2U, 24 SFF) for dense deployments; HP ProLiant DL360 Gen10 / Gen11 (1U) for high-density rack hosting; Supermicro 2U Twin (4-node-in-2U) for maximum-density VPS hosts.

For a typical managed-hosting node: 32-48 cores (dual Xeon Silver / Gold or AMD EPYC 7003 series), 512 GB DDR4-3200 memory, 4× 3.84 TB NVMe SSDs in software RAID 10, dual 25 GbE NICs. Lifetime per-customer cost on infrastructure runs $0.30-0.80/customer/month at scale.

If you're running cPanel / Plesk / DirectAdmin, we stock the platforms each control panel certifies. For Cloudflare-style CDN edge nodes, the short-depth XR-series + 4× 1.92 TB NVMe is the standard build. For static-asset/CDN cache, an L3 reverse proxy with 64+ GB RAM and a 1.92 TB NVMe cache tier is plenty.

Frequently Asked Questions

How many WordPress sites can a single server host?

Depends on traffic and caching. With NGINX + FastCGI cache + Redis object cache, a 32-core / 256 GB / 4× NVMe server hosts 5,000-15,000 low-traffic WordPress sites or 200-500 medium-traffic sites. The bottleneck is usually database connections, not CPU.

Do I need RAID for hosting servers?

Software RAID 10 (mdadm or ZFS mirrored) is the modern default — faster than hardware RAID for NVMe, and easier to monitor and recover. Hardware RAID still makes sense for SAS/SATA hot-swap deployments where the controller handles surprise drive removal.

Should I use AMD EPYC or Intel Xeon for hosting?

EPYC has higher core counts at lower TDP per core, which is a clear win for dense VPS / containerised hosting. Xeon Scalable has slightly higher single-thread clock and is more common in OEM hosting platforms. Most major hosts run a mix; we stock both.

What's the cheapest entry-level dedicated server you stock?

Refurbished Dell R430 / HP DL360 Gen9 with 32 GB RAM and 2× 1 TB SATA SSD — around $700-1,200 depending on configuration. For VPS-host work, refurbished R740 with 256 GB RAM and 4× NVMe SSD runs $4-7K and supports 50-100 VPS instances comfortably.
