建设和运营数据中心的常见问题
发布时间:2018-03-20 14:42浏览量:


当前,中小企业考虑将服务器迁移到数据中心时,可以采取租用现有数据中心或自建数据中心。无论采取哪种模式,企业必须避免那些可能存在的陷阱。

但是企业怎么知道该避免什么呢?以下是需要注意的10个常见的陷阱:

1
 

虚拟化不足

  如果企业没有采用虚拟化,那说明已经落后了。而在数据中心没有实现虚拟化,那么不仅是落后于人,也预示着需要花费更多的资金。用户可以拥有一台主机托管虚拟服务器时,为什么要为每个任务配置专用硬件呢?这不仅节省了成本,还可以节省空间,并且可以理想地构建一个更加可靠的环境。

2
 

扩展性有限

  如果企业在不考虑扩展的情况下建设数据中心,则会限制今后的发展。企业在构建数据中心时为了适应业务增长,需要为服务器预留大量内存和硬盘的空间,甚至为数据中心预留足够的空间。根据以往的经验,企业建设数据中心时需要考虑将容量加倍,这样就能够有足够的扩展空间。

3
 

云计算资源不足

  云计算是一个灵活的资源,每个中型企业都应该灵活运用。企业可以创建自己的云平台或从AWS购买云空间。无论采用哪种方式,都可以设置一个更加灵活的数据中心体验。即使只能进行云存储,至少企业可以不断扩展存储空间,而无需不断添加新硬件。

4
 

管理不善的服务器

  企业可能都看到了服务器管理不善所造成的结果。当管理服务器发生这种情况时,事情可能会变得更糟。企业需要确保其服务器保持最新状态,备份数据、备份电源等都需要进行定期维护。

5
 

设计不当和机柜货架狭窄

  工作人员在机架上工作时,配线架线缆会不会密集到无法下手?机架设计应易于操作(从前面和后面)。配线架必须清楚贴上正确的标签,电缆应该捆扎整齐得当。不要把所有的设备混杂在一起,这些将会花费大量的时间来设计货架布局。

6
 

数据中心电力不足

  如果企业的数据中心没有足够的电力,那么可能会容易遇到断电的情况,当企业大量服务器同时运行,电力容量不足会发生什么?因此,当企业设计或选择自己的数据中心时,请务必注意预留足够的电力容量,而不能是正好或太少。

7
 

安全意识薄弱

  许多人认为,由于他们已经使用了数据中心设施,所以安全性不再是一个问题。但不要这么假设,无论企业的服务器如何部署,要始终把安全放在首位。没有一个数据中心可以保证100%的数据安全。因此,企业在部署服务器时要有冗余,并且还需要有额外的防范和保护意识以应对威胁。
