With more and more businesses turning toward virtualization and cloud migration, it is evident that virtualization is enabling businesses to scale their servers make them more flexible. IT leaders and innovators at IT consulting company are taking strides in improving this technology. But besides businesses, Virtualization probably has left an impact on data centers and its physical infrastructure and how data center project management works.
Here is how exactly virtualization is affecting the infrastructure of a data center.
The rise of high density As per IT professionals from top IT consultant companies, virtualization’s most significant benefit is higher CPU utilization rate. It enables data centers to attain server consolidation ratios higher than 20:1. Besides these, it can be grouped to form localized high-density areas.
Reduced IT load effecting PUE Although high-density servers draw more power than simple servers, consolidation leaves only a few of them. This, in turn, results in a lower electricity bill. But consolidation of servers and storage can worsen the power utilization efficiency of the data center.
Data center deploy fixed losses approach to cooling. No matter how much power IT load is consuming, the power used for the assets and cooling remains constant. Though by consolidating server hardware through virtualization the IT load would decrease it will also reduce PUE.
Dynamic IT loads The most significant advantage of virtualization is the ability to move the load from one server to another. The automation of the technology has further increased the speed and ease to transfer data from one server to another. But if the movement of the data is not carefully monitored and managed, it can result in the decreased fault-tolerance ability of the software.
Lowered redundancy requirements Server virtualization reduces the need for redundancy. Besides the ability to move loads from one server to another, a well-monitored virtual server also offers an increased level of software fault tolerance. Whenever there is a problem or threat, data, virtual machines, and storage assets can be moved to a safe location instantly and automatically.
The level of fault tolerance provided by the technology reduces the need to keep redundant power and cooling systems. For instance, in a highly virtualized data center, the failure of an individual UPS will not result in disruption of business operation, nor it would require a backup.
Handling Deduplication No doubt deduplication of data is effective in reducing bandwidth and storage needs and eliminates the need to keep redundant data; it is CPU-intensive and slows down the performance. There are different methods to deduplicate the data which depends on the applications used by the data center.
Managing Enterprise Storage
Data storage is constituted by RAID arrays, volumes, and hardware that are mapped by Virtualization machines. Since virtual data storage structures are complex, the data stored in the server must map to its infrastructure. In the data center, workloads continuously move from one server to another; thus it is essential to track the relationship between the storage and the server to ensure that the data are available on VMs.
