Are your enterprise servers new and genuine?

Yes. We supply new and factory-sealed new-old-stock (NOS) servers from Dell, Lenovo, xFusion and Inspur, sourced through authorized manufacturer channels. New servers are covered by a 3-year warranty.

Can you ship GPU and storage servers to my country?

We export to 60+ countries across North America, Europe, the Middle East, Southeast Asia, Africa and Latin America, with door-to-door freight, customs documentation and insurance handled by our team.

How fast will I receive a quotation?

Most configuration lists receive a detailed quotation within one business day. For complex deployments, our engineers confirm compatibility and provide options before pricing.

Do you support system integrators and resellers?

Yes — system integrators, IT resellers, project suppliers and tender bidders are our primary customers. We offer multi-brand consolidation, neutral configuration advice and repeat-order account support.

How do I pay, and what terms are available?

We accept international bank transfer (T/T) in USD. Standard orders are confirmed against a proforma invoice, while established repeat accounts and project bidders can discuss agreed payment terms in advance.

What is the lead time for delivery to the Middle East or Southeast Asia?

In-stock configurations are normally built and tested within a few business days, followed by door-to-door air or sea freight depending on the destination. We provide a clear timeline and tracking once the order is confirmed.

How is warranty and after-sales support handled overseas?

New servers carry a 3-year warranty. Our support team coordinates with the manufacturer and arranges replacement parts and remote troubleshooting, so you receive the same level of service in any region we ship to.

Can you build a fully custom configuration to my specification?

Yes. Send your required CPU, memory, drives, accelerators, power and networking preferences — or simply describe the workload and target budget. Our engineers specify, assemble and burn-in test the complete system before shipment.

Data center switches and high speed server networking in an enterprise rack

Data Center Switches Explained: How to Choose the Right Switch

Networking buying guide · Updated 2026-09-29 · 9 min read

Choose a data center switch from port speed and count, the role it plays in the topology, and the buffer and software features your traffic needs — not from the largest port count in the catalogue. Matching the switch to ToR, leaf or spine use avoids most buying mistakes.

Short answer: define the role first

A switch that connects servers inside one rack is specified differently from one that aggregates racks or forms the spine of a fabric. Start by naming the role — top-of-rack, leaf or spine — then set port speed, port count, uplinks and buffering. That single step prevents the common error of buying an oversized or undersized box.

ToR, leaf and spine: what each role needs

A top-of-rack switch connects the servers in a rack and uplinks toward the rest of the network. It needs enough downlink ports at the server NIC speed and a smaller number of faster uplinks. In a leaf-spine design, leaf switches act like ToR aggregation points while spine switches provide a fast, predictable forwarding layer and are chosen for high throughput and consistent latency rather than for feature-heavy edge ports.

ToR / leaf: high server-facing port density at 10/25GbE, with 40/100GbE uplinks.
Spine: high-speed 100/200/400GbE ports, large switching capacity, low and consistent latency.

Port speed and oversubscription

Port speed should match the server NIC generation and the traffic pattern: storage, backup and east-west-heavy workloads reward faster links. Oversubscription compares the total bandwidth available to servers with the bandwidth that actually leaves the rack. A higher ratio costs less but can create contention; storage and high-performance clusters usually want lower oversubscription than general-purpose racks.

Plan uplinks so normal traffic does not saturate them, and leave headroom for maintenance windows when one link is down.

Buffers, latency and forwarding capacity

For storage, big-data and bursty workloads, buffer size can matter as much as raw throughput because it absorbs traffic bursts without dropping packets. Forwarding capacity must be non-blocking for the role, and cut-through switching keeps latency low in performance fabrics. General web tiers need less buffering and can prioritize cost and management simplicity.

Software and operations

Features such as VLANs, link aggregation, QoS, multicast, routing and EVPN support vary by software tier and licensing, so confirm the features you need are included rather than assuming a base switch exposes everything. Think also about how the device will be managed — command line, central management or automation — and how it integrates with the existing network.

Decision	What to confirm
Role	ToR, leaf or spine
Ports	Speed, count, uplinks and breakout support
Oversubscription	Acceptable ratio for the workload
Buffering	Enough for storage and bursty traffic
Software	Routing, EVPN, QoS and management features included

Buying switches with servers: why it helps

Specifying switches alongside the server and storage order lets us match NICs, cables, optics and transceivers end to end, which removes a surprising number of deployment delays from incompatible or missing parts. Tell us the server count, NIC speed, rack layout and growth plan and we will propose the ToR and uplink design with the correct optics and cables.

Frequently asked questions

What is the difference between a ToR switch and a leaf switch?

A top-of-rack switch connects the servers in a single rack and uplinks to the aggregation or spine layer. In a leaf-spine fabric the leaf performs a similar server-facing role but is designed around a flat, scalable connection to every spine switch. The terms overlap but leaf-spine designs emphasize scaling and consistent paths.

What switch speed do my servers need?

Match the downlinks to the server NIC generation, commonly 10/25GbE today, and provide faster 40/100GbE uplinks. Storage, backup and east-west-heavy applications benefit from more headroom, while lighter web tiers can use higher oversubscription to control cost.

What is oversubscription and why does it matter?

Oversubscription compares total server-facing bandwidth with the bandwidth leaving the rack. A low ratio gives servers near-full uplift but costs more; a higher ratio saves money but can congest under heavy traffic. Storage and HPC clusters generally require lower ratios than general-purpose workloads.

Do I need a managed or an unmanaged switch?

Data center deployments effectively always need managed switches because they require VLANs, link aggregation, QoS, routing, monitoring and firmware control. Unmanaged switches suit simple lab or office connections and lack the configuration and visibility a production network depends on.

What are optics and transceivers, and why do they matter?

Optics or transceivers are modules plugged into switch ports to carry fibre or copper at the required speed and distance. They must match the port type, cable and device on each end. Sourcing them with the switches and servers avoids the common problem of incompatible or missing modules at installation.

When should I move to 100GbE or higher?

Move to higher speeds when storage replication, backups, virtualization or east-west traffic regularly saturates existing links, or when a new server generation already includes faster NICs. Higher-speed uplinks are also normal at the spine layer, where throughput and consistent latency drive the design.
