feat: Add "server-room.md" Page to the Operations Basics Section

[ywh555hhh]

Description:
I have created a new page named server-room.md for the Operations Basics section, which aims to introduce basic information about small-scale data centers. This page is intended to provide Linux201 project users with essential foundational knowledge about data centers. The main content includes:

• UPS (Uninterruptible Power Supply): Ensures data safety during power outages.
• Switches: Core components for network communication.
• Physical Servers: The main computing units in a data center.
• Others: Additional relevant data center equipment and concepts will also be covered.

Discussion Points:
Can we clarify the focus of the existing server.md section? Should it cover detailed types of physical servers, like blade, tower, and rack servers? We need to discuss how server.md and server-room.md should relate to each other to ensure consistent and logical content organization.

server.md is intended for readers who have no experience with server hardware (and server rooms, of course). I think that server-room.md part could be merged to server.md.

Could someone please review the section I wrote about rack to see if it meets your expectations? Additionally, if there are any corrections or improvements needed, I would appreciate your feedback

	RAID 0
	: 也称作条带化（Striped），将数据分块存储在多个磁盘上，可以充分利用所有容量，获得叠加的顺序读写性能（但随机读写性能一般），但没有冗余，任何一块磁盘损坏都会导致整个阵列的数据丢失，适合需要高性能读写但不需要数据安全性的场景。
	RAID 1
	: 也称作镜像（Mirrored），将数据完全复制到多个磁盘上，提供了绝对冗余，整个阵列中只需要有一块盘存活，数据就不会丢失。代价是整个阵列的容量等单块磁盘的容量，空间利用率低下，适合需要高可靠性<s>而且不缺钱</s>的场景。同时由于每块盘上的数据完全一致，RAID 1 的读取性能可以叠加（甚至包括随机读取），但写入性能不会提升。
	RAID 5
	: 将数据和**一份**校验信息分块存储在多个磁盘上，可以允许阵列中任何一块磁盘损坏，兼顾冗余性和容量利用率。重建期间的性能会严重下降，并且一旦在重建完成前又坏了一块盘，那么你就寄了。
	!!! danger "不要为大容量机械硬盘阵列组 RAID 5"
	否则坏了一块盘后重建的时候就等死吧。
	下面的思考题也会涉及到这个问题。
	RAID 6
	: 将数据和**两份**校验信息分块存储在多个磁盘上，比 RAID 5 多了一份校验信息，可以容纳两块磁盘损坏，适合大容量或者磁盘较多的阵列。尽管允许两块盘损坏，但我们仍然建议在第一块盘损坏后立即更换并重建，不要等到更危险的时候。
	RAID 10, 50, 60
	: 将不同级别的 RAID 组合在一起，兼顾性能和冗余，各取所长，对于 10 块盘以上的阵列是更加常见的选择。例如 RAID 10 = RAID 1 + RAID 0，通常将每两块盘组成 RAID 1，再将这些 RAID 1 的组合拼成一个大 RAID 0。

It's been a long time -- do you still have interests in writing this?

I almost forgot about this PR too. I think I can try to pick it up and continue to improve it within the next month.
