Mediatrix units running a Virtual Machine are equipped with various sizes of Solid State Drive (SSD) for storage.
A Solid State Drive (SSD) is a form of flash-based storage. Media5 uses high quality, enterprise grade SSDs in its products. However due to its technical nature, flash memory can handle so many read/write cycles. Beyond that, the performance may degrade or in extreme cases, the drive may fail. For customers using a Mediatrix unit running a Virtual Machine, special attention should be paid to the number of writes caused by the Operating System running in the virtual machine, as well as by the application. If the Virtual Machine is not optimised, it will lead to excessive read/write access to the SSD, and hence significantly reduce the lifespan of the SSD. For more details, please refer to Technical Bulletins - Virtual machine installation published on the Media5 documentation portal at https://documentation.media5corp.com/ .
SSD lifespan can be extrapolated and Virtual Machine optimisation can be validated.
For example, let the virtual machine run for a month (or a week), read and compare the WearPercentage parameter at different times during this interval. Use the collected information to extrapolate the lifespan.
For example: the Wear Percentage increased from 19% to 20% in 2 months. Take the remaining 80% divided by a monthly increase of 0.5% gives 160 months left. Therefore at least 13 years left at the current increase rate.
If the lifespan does not meet the expectations, you may consider further optimisation measures e.g.:
The Mediatrix UMN Mib browser can be used for this procedure.
This is an SNMP (readonly) Mib.
