Uptime is a measure of system reliability, expressed as the percentage of time a machine, typically a computer, has been working and available. It is often used as a measure of computer operating system reliability or stability, in that this time represents the time a computer can be left unattended without crashing.
Data transfer is any information that is transferred from one location to another through some communication method. The amount of data is divided by the (average) transfer rate in order to find how long the transfer will take.
RAID (Redundant Array of Inexpensive Disks or Drives) or Redundant Array of Independent Disks is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both. This contrasted with the previous concept of highly reliable mainframe disk drives referred to as single large expensive disk
VMware I/O Analyzer is an integrated framework designed to measure storage performance in a virtual environment and to help diagnose storage performance concerns. I/O Analyzer, supplied as an easy-to-deploy virtual appliance, automates storage performance analysis through a unified interface that can be used to configure and deploy storage tests and view graphical results for those tests.
VMware IO Insight is a tool to help people understand a VM’s storage I/O behavior. By understanding their VM’s I/O characteristics, customers can make better decisions at storage capacity planning and performance tuning. IO Insight captures I/O traces from ESXi and generates various aggregated metrics that represent the I/O behavior. The IO Insight report contains only these aggregated metrics and there is no sensitive information about the application itself.
Make sure that the UPS can handle the total electrical load of the equipment that you want to connect to it. You can use our Load Calculator to determine your total load, and then choose a UPS with an Output Watt Capacity 20-25% higher than that total.
