Read Product Review CyberServe EPYC EP2-R182-Z90

Server manufacturer Gigabyte made a calculated move when AMD launched its second generation of core-dense EPYC CPUs. While the blue-chips chickened out and waited to see what demand would be, Gigabyte went full steam ahead and produced no less than 28 EPYC 7002 rack server solutions – more than four times the rest put together.

Gigabyte’s range is really quite remarkable: you can choose from 1U, 2U and 4U rack chassis with single or dual CPU sockets, plus 2U quad node hyper-converged systems. Memory choices range from eight to 32 DIMM slots, all supporting eight-channel DDR4, while there’s just about as many storage options as you can think of.

On review we have Broadberry’s CyberServe R182-Z90 which showcases Gigabyte’s 1U 2P rack platform and delivers a hardware package that defies belief. The price we’ve shown includes a pair of mighty 32-core 2.9GHz AMD EPYC 7542 CPUs teamed up with a generous 128GB of super-fast 3,200MHz DDR4 ECC memory.

With 64 physical cores up for grabs, enterprises that don’t want 4P or 8P platforms won’t find a better value solution this this - a single 28-core Xeon Scalable Platinum 8280 CPU alone will cost you more than this entire server. And of course, while Intel snoozed, AMD went ahead and produced the world’s first 7nm CPU.

Broadberry CyberServe R182-Z90 review: Build and design

The CyberServe chassis is very well constructed and removing the lid reveals a smartly designed interior affording easy access for upgrades and maintenance. The dual EPYC 7002 sockets are located towards the front of the motherboard and flanked on each side by a total of 32 DIMM slots, allowing memory to be boosted to a massive 4TB.

Expansion options are very good for a 1U chassis; the server offers two PCIe Gen4 x16 slots on risers both with room for full-height, half-length adapter cards. The extra bandwidth of these Gen4 slots means the server can support the latest high-speed 50GbE and 100GbE network adapters.

Of equal interest are the two OCP (Open Compute Project) slots at the rear. Along with an OCP 2.0 Gen3 slot, the server has an OCP 3.0 Gen4 version and its tool-free design allows industry-standard mezzanine cards to be easily slotted in from the rear without needing to open the server’s lid.

All of Gigabyte’s servers support every EPYC 7002 CPU including the 48 and 64 core models. Furthermore, they are certified to support a cTDP (configurable TDP) of up to 240W which offers a potential performance boost and can be manually set from the server’s BIOS.

Broadberry CyberServe R182-Z90 review: Storage features

The CyberServe comes with four hot-swap LFF/SFF drive bays across the front. No drives are included but the server comes with Gigabyte’s nifty tool-free drive carriers as standard and Broadberry allows you to install your own choice of drives without invalidating its warranty.

Two on-board four-port SATA connectors are provided but the motherboard doesn’t have any embedded RAID, so you’ll need to source an extra controller. Broadberry offers a good range of hardware RAID adapters, with the MegaRAID 9341-4i option delivering all the usual RAID suspects plus SAS3/SATA device support for the princely sum of £200.

The motherboard also has a single M.2 NVMe slot and the price includes a 1TB Intel 660p NVMe SSD card. This is a useful feature as you can run your OS or hypervisor from it and reserve all four front bays for data storage duties.

More storage choices are on the table for Gigabyte’s 1U systems. For example, the CyberServe R182-Z91 model comes with eight hot-swap SFF and two NVMe SSD bays. Businesses that want maximum storage performance may prefer the R182-Z92 version which sports a full complement of ten hot-swap U.2 NVMe bays.

Broadberry CyberServe R182-Z90 review: Power, cooling and management

The system was supplied with a meaty pair of 1200W hot-plug redundant power supplies and AMD scores another win over Intel thanks to the EPYC’s low power demands. The EPYC 7542 CPUs may have a high 225W TDP but we recorded the system drawing 110W in idle and peaking at only 446W with all 128 logical cores under maximum load – a 1U rack server in the lab with dual 28-core 2.7GHz Platinum 8280 CPUs peaked at a much higher 672W.

Cooling is handled efficiently by a bank of eight cold-swap, dual-rotor fans behind the drive backplane. Operational noise is noticeable but not excessive for such a powerful system, and we measured sound levels of just 61dB from one metre in front of the server.

Gigabyte has improved its remote management offerings with the embedded AST2500 IPMI controller presenting a freshly designed web interface packed with valuable information. Its new dashboard keeps you posted on all critical issues and you can dive deeper to view hardware sensors, link their thresholds to email alerts, control power and run full OS remote control plus virtual media services.

Gigabyte’s Server Management (GSM) utility offers a web console that provides a status and power dashboard for remotely monitored systems along with views of installed hardware and sensors, fan speed graphs and tools for remote firmware upgrades. Free mobile apps are also available and we used the iOS version on our iPad to link to the central GSM server and view graphs on system availability and health.
