Picking between VMware and Hyper-V

Picking a hypervisor has become an increasingly difficult proposition. The technology you choose may depend less on the technical differences between the hypervisor technologies and more on your strategic direction and the type of IT resources you already have in place.

How Much Memory Does Microsoft’s SQL Server Need?

Microsoft SQL Server uses memory to improve performance by caching data, and it will use as much memory as it can based on how much it has been allocated. On a physical server, with a fixed amount of memory, that means making an initial estimate of how to divide the limited system memory between SQL, the operating system, and other applications on the server.

Securing and Optimizing the Virtual Network Infrastructure

An efficient and fully functioning VMware infrastructure is dependent on shared virtual resources that include server, network, and storage - but the glue that holds the virtual infrastructure together is virtual network resources.

VMware Distributed Resource Scheduler

As we’ve discussed in previous posts, VMware can ensure uptime in the event of a hardware failure via its High Availability (HA) feature. HA detects when a VMware ESX host fails, and uses vMotion to move the virtual machines (VMs) on the failed host to an available host in the cluster. However, HA does not monitor VM performance and will not move VMs to a different host if they would perform better on that host. That’s where VMware’s Distributed Resource Scheduler (DRS) comes in.

Monitoring for Availability

You’ve set up server monitoring, and your CPU, memory and disk I/O values are all within baselines. The server responds to a ping, and your web services are all running.  But when you try to pull up your company’s home page, you get a “

VMware – High Availability and Fault Tolerant Cluster Configurations

While virtualizing servers with VMware has the advantage of minimizing hardware monitoring requirements and saving on facilities costs, it does have the disadvantage of introducing a single point of failure for multiple servers:  the ESX host computer.  One hardware failure taking out an ESX host can take out all the Virtual Machines (VMs) on that host, rather than taking out one individual server.
