数据中心基础设施 - 规划高可用性基础设施

我是数据中心基础设施的新手,正在解决一些练习。我遇到了一个我无法回答的问题,所以我很英雄地寻求帮助。问题是:

1) 在规划一个包含 20 台机器的高可用性基础设施时,我需要 SAN,有人向我提出了 3 种不同的解决方案:

  • a) 基于光纤交换机来连接机器的解决方案 到SAN,无冗余。

  • b) 完全基于iscsi的解决方案;

  • c) 一种解决方案,允许我仅将 8 台机器连接到具有冗余的 SAN;

由于这些解决方案都不是理想的,为了确保所有机器都能访问存储,可以推荐哪些解决方案/更改?为什么

请帮忙, 谢谢

I'm new to Datacenter infrastructure and I'm solving some exercises. I came across a question that I can't answer so I'm hero to ask some help. The question is:

1) In planning a high availability infrastructure with 20 machines on wich I'm gonna need a SAN, someone propose me 3 distinct solutions:

  • a) A solution based on optical fibre switches to connect the machines
    to the SAN without redundancy.

  • b) A solution completely based on iscsi;

  • c) A solution that allows me to connect only to 8 machines to a SAN with redundancy;

Since none of this solutions is the ideal, which could be the solution/changes that could be recomended in order to ensure the access to storage from all the machines? Why

Please some help,
Thanks

好吧,让我给你一个不包括a、b或c的答案。

我要做的是采用虚拟化架构(我将在这里使用 VM-Ware 作为示例),将尽可能多的机器移动到虚拟化解决方案中。

在硬件级别,您设置具有双 SAN 交换机的 SAN。这些交换机连接到每台机器的光纤通道 HBA。实际的机器可能是刀片中心中的刀片。

每个刀片服务器都应配备尽可能多的功能,2 个 10 核 CPU 是一个不错的选择。通过这种方式,您可以在尽可能少的刀片中安装尽可能多的虚拟机。

由于您正在谈论 H/A,您很可能希望拥有足够的冗余来松开一个完整的刀片,并在其余刀片上重新启动机器,而不会对性能造成太大影响。

在线服务/维护可以通过 V-Motion 等产品来处理。

基于此设置,您可以继续构建 H/A 集群环境。

Ok, let me give you an answer that doesn't include a, b or c.

What I would do is go with a virtualized architecture (I will use VM-Ware as an example here) where you move as many as possible of the machines into your virtualized solution.

On a hardware level you set up a SAN with dual SAN-Switches. The switches are wired to Fibre-Channel HBA:s per machine. The actual machines would probably be Blades in a Blade Center.

Each Blade should be stuffed with as much power as you can, 2 x 10-Core CPU:s is a good choice. In that way you can fit as many virtual machines in as few blades as possible.

Since you are talking H/A you most likely want to have redundancy enough to loose one full Blade and have the machines restarted on the remaining Blades without affecting the performance too badly.

Online Service / Maintencance can be handled by products like V-Motion.

Based on this set up, you can continue building a H/A clustered environment.

您可以使用具有更多端口的交换机,也可以使用分布式拓扑,其中附加交换机为附加服务器提供附加连接。

server  === \
server  ==== \
server =========FC Switch 1 ===two X connections  FCSwitch3
server =========FC Switch 2 ===two X connections  FCSwitch4
server  ==== /
server  === /

You can use switches with more ports, or you can use a distribution topology where additional switches provide additional conectivity for additional servers.

server =========FC Switch 1 ===two X connections  FCSwitch3
server =========FC Switch 2 ===two X connections  FCSwitch4
server  ==== /
