10 terms to understand before choosing a server

To buy a server, we need to know the server related to know. Just as we learned to read from elementary school, there are some normative knowledge that must be understood, that is terminology. The ten most relevant terms for the server are as follows:

1. Enterprise (Enterprise):

Refers to any large or medium sized company (or non-profit organization or government agency). Generally, we use "enterprise" more frequently, mainly because it is more extensive than the business organization or company contains.

2. Base Price

Starting price ("... Yuan "), is basically much lower than the ultimate cost of owning a server. For example, IBM's xhttp://www.aliyun.com/zixun/aggregation/16960.html ">series 365 has a bottom price, 999 of the 4-way rack-Optimized Xeon server." Standard two processors, upgrade to four additional requirements, 498. This does not include the operating system, Windows 2003 Enterprise Edition to Spend, 209, memory standard 2 GB, to upgrade to GB, and then spend, 788, six hot swap hard disk, plus a set of the cheapest keyboard and monitor, The final price is 930.95, which is about four times times the reserve. Of course, companies can also choose a cheaper Linux operating system, or choose a cheaper option, but no matter what, for a 000 of the server, add about 000 of the option is the most common.

3. Entry level (entry-level)

The bare simplest configuration--in a sense, can hardly be called a server. For example, Dell describes its PowerEdge SC as a premium entry-level server, with a "premium server for small companies" starting at 9, which is the ideal choice for users who are more concerned about costs and are buying the server for the first time for simple it needs. "In other words, the server does not need to add any fees, in fact, because it does not deserve to add the place." This product is described as "easy to install, run and repair"--there is not much that can be run on it, and of course it is impossible to have too many problems. (It can be a file/print server with less than 10 users, but this is the ability of a normal PC.) )

4. Key business (Burritos unacknowledged)

Most of the business that runs the key business (burritos unacknowledged) is not the financial loss of the hardware damage, but the immeasurable economic and reputational damage to the business's production, operations, security, and even the enterprise's customers due to an abnormal business shutdown.

From high-end bank securities, hospitals, steel manufacturing, traffic control centers, national defense policing, to the low-end of the large supermarkets, conventional traffic, there are visible to the high availability of systems (Hight availablilty System, hereinafter referred to as HA systems) urgent needs. It vendors (IBM, HP, etc.) that provide business-critical solutions to the enterprise have a holistic approach that combines their own hardware environment to customers who need the HA system.

Most of these scenarios are based on RISC UNIX systems and high-end storage platforms. Whether the purchase of products and services in these programs, or the cost of maintenance later, is a big expense for most enterprises. Intel Architecture Servers (IA32) are not considered and accepted by businesses that need to run critical business because of their low performance, low scalability, and low reliability. But with Intel's aggressive expansion of the IA platform in recent years, and large-scale follow-up by companies such as IBM, HP and Dell, more and more companies are considering and accepting Low-cost PC servers based on the IA platform to replace expensive RISC servers. The original HA program providers have also launched a fierce competition for HA products and programs on the PC server platform.
