The KR4480V2 is a high-end 4-socket rack server powered by the 4th Gen Intel® Xeon® Scalable processors. Optimized for
customers' data-intensive critical services, the server features powerful computing performance, flexible modular design,
excellent scalability, and enhanced reliability and security, making it suitable for application scenarios such as large transaction
databases, in-memory databases, virtualization integration, HPC, deep learning, and ERP
Powerful Computing Performance
Supports 4 new-gen Intel® Xeon® Scalable processors, with up
to 60 cores and 120 threads per CPU, up to 350W TDP, and 3
Ultra Path Interconnect (UPI) links per CPU at up to 16GT/s per
link, significantly improving its cost performance in virtualization scenarios.
It supports 64 DDR5 ECC DIMMs (4,800MT/s, RDIMMs),
delivering superior speed, high availability, and a memory
capacity of up to 16TB.
The all-flash configuration of 24 NVMe SSDs provides a high
IOPS ten times higher than that of high-end enterprise-level
SATA SSDs, boosting the storage performance.
With 4 dual-width GPUs or 8 single-width GPUs, it provides
ultra-high AI training performance to meet customers' computing needs in deep learning, inference, training, etc.
Flexible Modular Expansion
The I/O modular design supports 2 full-height modules that can
be flexibly deployed to fit customer requirements on scalability
The modular design of drive modules enables the server to
support multiple flexible drive configurations, providing elastic,
scalable storage capacity to meet different storage capacity
and upgrade requirements.
It supports up to 24 front 2.5-inch
SAS/SATA/NVMe drives or 21 front 2.5-inch SAS/SATA drives
and 4 NVMe drives, and supports 8 directly-connected SATA
drives onboard. It supports 2 internal M.2 SSDs and 12 3.5-inch
drives to store the data in layers.
Supports 4 PCIe expansion slots onboard and 12 PCIe expansion slots through riser cards, as well as 4 dual-width GPUs or 8
Supports 2 hot-swap OCP 3.0 slots that can flexibly support
1/10/25/100/200Gb OCP 3.0 cards (multi-host); the OCP 3.0
cards can connect to 4 CPUs at the same time, improving the
performance by 20%.
Multi-Dimensional and High-Reliability Design
Supports hot-swap SAS/SATA/NVMe drives. With RAID cache
and data protection enabled by the super-capacitor in case of
power failures, SAS/SATA drives can be configured to RAID
0/1/1E/10/5/50/6/60 depending on the RAID card in use.
The LEDs for fault diagnosis on the front and rear panels, the
plug-in LCD module, and the ISBMC Web GUI indicate the
statuses of key components and quickly lead engineers to failed
(or failing) components, simplifying maintenance, speeding up
troubleshooting, and enhancing system availability.
The BMC management network port on the rear panel enables
local O&M through ISBMC, improving O&M efficiency.
Provides 4 hot-swap PSUs with N+M (M≤N) redundancy;
provides 12 hot-swap fan modules with N+1 redundancy,
improving overall system availability.
The ISBMC monitors system parameters in real time and sends
alerts in advance, enabling engineers to take corresponding
measures in time to minimize system downtime.
Security, Trustworthiness and Easy Management
Provides security-enhanced TPM 2.0 and TCM modules and
secure measurement for trust, establishes a complete
hardware and software trust chain, and discovers malicious
intrusion and device replacement in time, so that worldwide
customers can ensure the security and controllability of their
Supports the trusted Intel PFR boot to effectively prevent
network attacks against firmware and safeguard customer's
data and assets.
The security panel design supports the intrusion alert function.
Online memory diagnosis helps service engineers quickly locate
the failed DIMMs, improving maintenance efficiency.
ISBMC4, an intelligent remote server management system
developed independently by us, supports mainstream management specifications in the industry such as IPMI 2.0 and
Redfish 1.8, greatly simplifying device deployment, management and maintenance of users, and providing higher operational reliability, easier maintenance and more accurate and
comprehensive fault diagnosis capabilities.
4U rack server
