Xserver Rental Server Goes Beyond 'Japan's Fastest': Launching a New Server Environment with Latest Hardware

Xserver Inc. (Headquarters: Kita-ku, Osaka; Representative Director: Naoki Kobayashi) announced that as of March 27, 2026, it has begun providing a new server environment for its rental server service 'Xserver,' which holds the No. 1 market share in Japan (*1). This new environment is powered by the latest 5th Generation AMD EPYC™ processors, which are highly acclaimed worldwide.

The new server environment offers significant enhancements in processing performance, disk performance, and memory capacity compared to previous environments.

By further improving upon the fastest server speeds in Japan (*2) and ensuring high stability, we provide an environment where businesses and information dissemination can be conducted with peace of mind.

■ Features of the New Server Environment

Since the inception of 'Xserver,' we have consistently provided the latest server environments. At the core of this, we have continued to adopt AMD EPYC™ processors, and we have integrated the latest models into this new server environment as well.

◆ Equipped with 5th Generation AMD EPYC™ Processors

We have adopted the latest 5th Generation AMD EPYC™ processors, which excel in large-scale data processing and parallel processing. Each server is equipped with 128 cores and 256 threads, delivering exceptional performance.

◆ Processing Performance Increased by Approximately 40%

Through the adoption of the latest hardware and optimization of server configuration, server processing performance has increased by up to approximately 40% (*3) compared to our previous environment. This allows for more stable site operation than ever before, even during sudden traffic spikes or high-load processing.

◆ Disk Performance Increased by 64 Times

With this latest hardware configuration, we have significantly enhanced disk I/O (Input/Output) performance, which represents data read/write capability. The performance of 'NVMe,' the high-speed connection interface we have traditionally used for all storage, has been further improved. It achieves up to 64 times (*4) the read speed compared to general SSDs (all-SSD or pure SSD) widely used as high-speed storage.

◆ Memory Capacity Increased to 2.3TB

The installed memory capacity has been increased from 1.5TB to 2.3TB, enabling faster and more stable operation.

◆ Existing Customers Can Also Migrate to the Latest Environment

We offer a 'New Server Easy Migration' feature, which requires no specialized knowledge or complex migration tasks. Existing customers can utilize the latest server environment at no additional cost.

※ The server provision with enhanced hardware applies to new server applications made on or after Friday, March 27, 2026.
