Top 4 Use Cases for Migrating Virtual Machines

One of the advantages of VMware vSphere is that you can move a virtual machine (VM) from one location to another, across servers, storage locations — even data centers. Physical servers don’t have that ability and that can have many implications for disaster recovery, availability, etc.

Top 10 Must-See Sessions at VMworld 2014

After missing last year, I am headed back to VMworld in San Francisco. By the looks of the schedule builder bursting with a whopping 375 sessions, not counting repeat sessions, in only 19 timeslots spread over four days, it’s going to be a busy week.

Good Reasons to Get VCP5-DCV Certified

Achieving VCP5-DCV certification is a good way to distinguish yourself from others in the virtualization community. It’s also a great way to validate your technical capabilities as you look to advance your career. But that’s not all.

What is VMware VSAN?

Up until now, the cost of managing and maintaining storage was deemed unavoidable and worth it to ensure high availability, shared access across hosts, low latencies, etc. These features will still probably be required for large, complex companies (and for core data center functions, etc.) for years to come, but in many other cases, they may not be required.

VMware Resource Pools: Building Blocks

An assessment revealed that in a company’s current physical environment, the total RAM usage of the Windows servers during times of peak demand was 128 GB, which was 67% of the total RAM capacity of 192 GB. This led to a decision to allow 150% RAM over commitment for the Windows VMs. After analyzing the existing servers and planning for growth for three years, the predicted total configured RAM for all VMs was 450 GB. But, to allow 150% over commitment, only 67% of the estimated, or 300 GB, was procured for direct use by VMs. More RAM was actually purchased to allow overhead and spare capacity for ESXi downtimes, but only 300 GB was planned for direct VM usage.

VMware Resource Pools: New Test Environment

A company had a hundred traditional, physical, Windows servers in production that they wanted to migrate into a new vSphere environment. They intended to duplicate each production server to create a hundred test virtual servers, each configured identically to its production counterpart, except they would run in an isolated network.

Where Do I Get vCenter Operations Manager (vCOPS)?

For years, vSphere has had alarms to let you know when things are above or below thresholds you specify. This is a great first step in identifying items that may require your attention and/or further investigation. The problem is that these thresholds are static; you set a value and are notified if it is above that value, such as CPU utilization > 75%. While useful, it can lead to many false alarms if you have a virtual machine (VM) that routinely exceeds that value or one that spikes to that value for a while during a batch-processing interval.

Enter vCenter Operations Manager (vCOPS). Let the computer do what it does best: monitoring and alerting, figuring out what is “normal,” and then notifying administrators when things are abnormal.
