Physical Server vs. Virtual Server Comparison & Benefits

像“十大赌博正规老平台器场”这样的术语往往会让人想到一个特定的图像——一个有一排排闪烁着灯的黑盒子的仓库. Those are servers, right? Yes, but the top-of-mind image begs one question …

Is a Server Physical or Virtual?

When we picture a server farm or data center, what we’re imagining are physical servers, so called because they are here with us as tangible, physical data center infrastructure. 物理十大赌博正规老平台器是电子设备，与我们的电视或智能手机没有太大区别.

But not all servers are physical. Today, many organizations rely primarily or exclusively on virtual servers, and those are something different.

Physical Server vs. Virtual Server

在我们进入物理与虚拟的问题之前，我们是否清楚什么是十大赌博正规老平台器? Because it will come up later.

为了确定起见，十大赌博正规老平台器之所以得名，是因为它通过网络向计算机提供资源. There are various types of servers, typically named for what they do — email servers, application servers, file servers — you get the picture.

第一批十大赌博正规老平台器是物理的，通常只部署一个功能. As computing power increased per server, 我们了解到，我们可以虚拟化十大赌博正规老平台器硬件，并使用少量硬件资源执行相同的功能. Now servers come in both flavors. What is the difference between a physical server and virtual server?

What Is a Physical Server?

A physical server refers to a piece of hardware. It’s a recognizable machine with motherboard, CPU, memory, and the like. Often referred to as “bare metal servers,物理十大赌博正规老平台器在物理硬件和操作系统之间没有鸿沟. A physical server might run Linux, Windows, or some exotic O/S but it will run only one O/S in one instance.

What Is a Virtual Server?

虚拟十大赌博正规老平台器是物理十大赌博正规老平台器的抽象，并模拟这些十大赌博正规老平台器的功能. Multiple virtual servers can be deployed on a single physical server, and that’s one of the key advantages of the technology, as we’ll soon see.

If a physical server can only run one type and one instance of the O/S. If a physical server houses multiple virtual servers, on the other hand, these virtual servers operate like independent servers. 每个十大赌博正规老平台器运行自己的O/S，并使用其指定的计算资源分配, memory, storage and even network components.

Physical Server vs. Virtual Server—When to Use One over the Other

What if you’re considering a virtualization option like VMware vs. physical server technology? Which is best?

Unfortunately, there’s no simple answer. 当涉及到物理十大赌博正规老平台器和虚拟十大赌博正规老平台器时，两者都不是赢家.

• Virtual server vs. physical server performance – that battle goes to the physical server
• Virtual server vs. physical server cost – the virtual server emerges victorious in the end.

As with so many things in technology, it’s a matter of selecting the best option for the particular use case.

Take cost, for example. If you’re starting from nothing, 购买一台物理十大赌博正规老平台器，再加上在其上创建虚拟十大赌博正规老平台器的软件，乍一看似乎是更困难、更昂贵的选择. 只要需要升级十大赌博正规老平台器或正在虚拟化现有环境，平衡就会提示. It is less expensive to upgrade virtual servers, 因为您不必购买新的硬件来运行它们. The upgrade migration tends to be easier to complete.

Server virtualization also drives efficiency. Without virtualization, server utilization rates can be quite low. 迁移到虚拟十大赌博正规老平台器允许组织使用相同数量的物理机器完成更多的工作, and without increasing the footprint in the data center. In the early days, a single physical server could run 10 or more virtual servers, and capabilities have only increased.

There are typically energy savings as well, because servers are hungry for electricity even when doing nothing. 从环境(和电费)的角度来看，把这些精力花在这样做上是更好的 something. 一台十大赌博正规老平台器以高利用率运行比10多台十大赌博正规老平台器使用更少的电力.

Benefits of Virtual Servers and Physical Servers

Let us sum it up:

• 物理十大赌博正规老平台器的绝对性能使其成为要求苛刻的工作负载的首选. If processing speed and/or volume are primary considerations, look to physical servers as your workhorses.
• Virtual servers, on the other hand, are masters of scale. 需要灵活伸缩资源的组织通常会更好地使用虚拟十大赌博正规老平台器, especially if budgets are tight. 这对初创企业和中小企业来说非常好，但也适合大型企业更多变的需求.

Virtual Machine vs. Server—Same or Different?

Remember solving analogies like these in high school?

Physical server: virtual server: physical computer: virtual desktop (VDI)

也就是说，物理十大赌博正规老平台器和虚拟十大赌博正规老平台器之间的关系与物理计算机和虚拟计算机(我们称之为虚拟桌面)之间的关系相同. 虚拟十大赌博正规老平台器和虚拟桌面都是物理十大赌博正规老平台器的抽象(或虚拟化)版本.

pc和十大赌博正规老平台器不是一回事，所以vdi和虚拟十大赌博正规老平台器也不一样. PCs provide services, such as software applications, for a user; servers deliver resources to multiple PCs.

您有时会读到，虚拟十大赌博正规老平台器和虚拟桌面之间没有区别, or you’ll stumble across explanations of a virtual vs. physical machine that conflate PCs and servers. In fact, 这两个词互换使用的频率之高令人惊讶，甚至有点令人沮丧, even by reliable sources on IT topics.

Yes, a server is a type of computer, and a physical PC can be configured to operate as a server, as some IT pros do at home. Functionally speaking, servers and computers are different, as are virtual servers and virtual desktops, and it’s best to keep the terminology straight.

使用Park Place技术支持您的物理和虚拟环境

在了解了这些物理和虚拟环境之后，您可能会有一些疑问. If physical and virtual servers are two different things, 您是否需要两个不同的支持提供商来保持混合基础架构以最佳性能运行? Since virtual infrastructure still runs on physical hardware, 您是否需要虚拟维护专家和物理维护提供商? Absolutely not!

Park Place Technologies brings together the resources necessary to support, maintain, troubleshoot, and repair physical servers, as well as virtualized servers and the physical hardware on which they, too, run:

• Our third-party hardware maintenance 是否有所有物理设备，无论您是否需要存储，网络或 server maintenance. When it breaks, we fix it.
• ParkView Hardware Monitoring™是始终保持警惕的眼睛，负责监督物理设备，主动识别硬件事件并提醒维护团队，以便他们能够立即解决问题.
• Finally, ParkView Server Management™ is an agentless installation supporting multiple O/S instances and hypervisors to maximize uptime for both physical servers from one or various OEMs, along with virtual servers of different varieties as well.

Three tools, one infrastructure managed services provider. That’s the way it should be. 因为无论您的基础设施多么复杂，您都只是一个组织. 您应该得到一个完整的、集成的、优化的支持解决方案.
