Fiber, fibre and OM4!
November 12, 2014What’s the difference?
The words Fiber and Fibre are often swapped, most people assume that it is American versus UK spelling, but that is wrong. Fiber is actually the Fiber optic cable whereas Fibre is a generic term to describe the Fabric, which can include both Fiber and Copper technology that links your storage, switches and servers.
OM stands for Optical Multi-mode (multiple rays of light simultaneously) and the 4 refers to the latest version that can extend communications up to 300 meters at 10 Gb/s.
Once written it can’t be overwritten!
November 4, 2014The Program Erase Cycle.
It is true that once a block of data has been written to a Flash drive that it can’t be overwritten, it must be erased first before it can be written to again. This sequence of writing, erasing, and then writing again is known as the Program/Erase cycle. The Program/Erase cycle can serve as a criterion for quantifying the endurance of a flash storage device, it also has another name – Write endurance.
HP Enterprise SSDs are available in four categories based on their Write endurance: Performance, Mainstream, Light, and Value. Choosing which is right for you is generally based on the ‘typical workload’, that is the type of use i.e. high read / write applications require Performance, mixed read / write applications for Mainstream or Light and high read / low write applications for Value.
