Telecommunication Server Racks
nVent 此次发布的新一代电信级数据中心计算平台 (Schroff ServCite rack) 以OCP 开放架构为基础, 专门为适应电信级别的应用需求而做出升级, 在抗震/防冲击, 散热等关键性能指标上做出特殊加强. 这一开源机架级硬件解决方案由机柜, 机架顶部交换机, 电源子系统及计算/存储单元等模块组成。
ServCite rack的设计方案, 已经获得OCP组织的审核和批准, 成为CG-Openrack-19标准的一个重要组成部分
- 各机械部件均可按需定制, 例如: 机架高度, 宽度, 深度, 色泽, 内部计算/存储模组的位置
- 可选配多种配件, 例如: 电子门锁, 水冷解决方案 (安装于后门板), 智能机架管理
- 可集成PSU, PDU, 交换机, 计算/存储模块机械框架, 数据光纤
- 抗震, 防冲击能力达到UBC-1997 ZONE4 标准
- 可选配模组内电源转接板(12VDC至主板), 以及光-电转换解决方.
The ServCite Rack is based on the concept of OCP (Open Compute Project). OCP is an industry-wide initiative for defining the specifications and designs for the most energy efficient and economical data center possible. There are, however, additional requirements for environmental and mechanical durability in the telecommunications industry that are not covered in the OCP standard.
The Schroff ServCite rack meets the requirements and fulfills design considerations for telecommunications applications . The nVent offering comprises a rack with shelves, ToR (Top of Rack) switches, a power shelf, and sleds for computing or storage intensive applications.
ToR – Top-of-Rack Switch for optimized cable handling Storage Sled – 2U, full width, 800 mm deep.
An example configuration contains a single Dual-socket Xeon motherboard with 2x10 Gb optical NICs for Data Plane, 2x1 Gb optical NICs for BMC and Management and up to 256 GB RAM.
Compute Sled – 2U, half width, 800mm deep.
An example configuration holds 2x Dual-socket Xeon motherboards each equipped with up to 256 GB (16x 16 GB) RAM.
Power Shelf to provide 12V power supply to the busbar Power Busbars distribute 12V power to the sled Fiber Optic links between sleds and ToR switches Front side of rack Rear side of rack
The new generation of telecommunication system based on OCP is breaking down the barrier between a rack and a carrier grade shelf. Sleds are directly plugged into the rack, compared to the traditional concept of a system with blades installed inside a rack.
The nVent offering comprises a rack with the following components:
The Open Rack describes the cabinet, which contains the shelfs and sleds. The rack delivers the OCP infrastructure, including power distribution, cable management and if applicable cooling.
The shelf hosts different configurations of sleds
and provides access
to the power busbars as well as the connection to an optical header for the uplink to the switch.
A sled is hot swappable, connected to the Top-of-Rack Switch and can be either a Computing sled or a Storage sled. The height is 2 U and the width will either be half-wide or normal wide depending on the sled configuration. Both sled types can easily be combined in any configuration.
The power shelf is located
in the bottom of the rack.
It contains a number
of front pluggable PSU’s which can be configured
in N+1 or 2x N+1 or
other redundancy configurations. Variants
for AC, HVDC or -48V DC voltage are available.
