Data centers are changing the way they operate, and with the introduction of virtualization into the production environment and servers, energy efficiency and economic benefits have increased.
Server virtualization is a great way to derive value from the existing servers, dividing them into separate virtual machines. Basically, a bunch of servers are taken that are running at maximum capacity and creating virtual machines out of them. This way, you have fewer servers to run, while the virtual machines save considerable power, energy, and management efforts. So, when you implement server virtualization on a blade platform, you get dual benefits. For the same unit of servers, you get to implement the technologies together.
Blade Server for Virtualization:
Blade Servers and Virtualization are the key building blocks for Next-gen Enterprise data centers. That is so because Blades are modular, ultra-high-density servers (with up to 10x more capabilities than traditional servers). These have shared components like power, cooling, and switches which reduce complexity and cost but improve their management, maintenance, availability, and flexibility.
These servers offer a real deal density advantage at a premium price. One of the standouts of blade servers is that they enable centralized management through a single interface. You can see all the servers simultaneously and work with them all together. You can create server profiles, set up VLANs, add network and SAN, manage power, etc. And these are also the advantages of blades.
Moreover, blade servers enabled IT admins to connect to blade server management via a secure shell. With such an interface, many keyboards’ interactive commands can be facilitated by admins for the system.
On the other hand, virtualization seeks to consolidate physical servers by creating many virtual servers that run concurrently on the physical server. As a result, system utilization improves, the need for additional servers reduces, flexibility increases, and businesses save considerable expenses.
How to Virtualize Blade Servers?
Having said that, not all blade servers come configured for virtualization. But, as an enterprise, you can still configure blade servers and counter the virtualization lacks by optimizing various components such as:
- Select suitable virtual machines for each processor blade.
- Maximize server RAM.
- You can optimize network and storage accessibility.
- Provide proper support for new virtual I/O standards.
*You can also optimize the existing or older blade server environments to enhance the virtualization operations. Do not forget to analyze hardware and software requirements to provide your data center with the best possible performance from older or new blade systems.
Features of Blade Server Virtualization:
Robust System: Blade server virtualization consolidates multiple physical servers into a small number of virtual servers. By enabling numerous
virtual machines in a single-blade server, organizations can significantly maximize the use of servers. At the same time, they can reduce significant hardware costs and save floor space in the data center.
Proper Resource Allocation: Through virtualization, you get appropriate tools to allocate computing resources like CPU, memory, and storage to virtual machines running on blade servers. Doing so ensures efficient utilization of computing resources and reduces any scope of underutilization and over-provisioning.
Real-time Migration: Blade Server Virtualization facilitates real-time migration of virtual machines from one blade server to another without causing any downtime or disruption to the running applications. Such a feature is quite helpful in situations like load balancing, maintenance, and improving virtual machine usage and reliability.
Ensures High Availability: With blade server virtualization platforms, various features get unlocked, such as failover clustering and automatic virtual machine restart. These features are helpful in case of hardware failure or server outage. It ensures the availability of critical applications at all times and reduces downtime.
Management and Monitoring: Virtualization eases interface management through a central repository. It allows the admins to manage and control the entire blade server infrastructure and virtual machines running on them. Some of the tasks admins can undertake are virtual machine provisioning, configuration, performance monitoring, troubleshooting, etc.
Easy Scalability: Blade server virtualization enables scalability for the virtual infrastructure. You can add more blade servers to the existing environment to cater to the growing demands of resources and applications. Additionally, virtualization platforms can efficiently manage the increasing number of virtual machines and distribute the workload evenly across the blade server infrastructure.
Disaster Recovery & Management:
With blade server virtualization, disaster recovery gets simplified. Organizations can replicate, backup, and restore virtual machines daily. Moreover, they can create replicas of virtual machines on remote locations or backups to keep the data safe and protected so you can recover it when a disaster strikes.
Technology is changing fast, and so are the needs for data centers. With blade servers, organizations are sure to address various issues that otherwise wouldn’t have been possible, making the data center more robust and efficient while cutting out significant expenses in keeping up its operation.
