What are the frequently asked questions about SolidFire Drives?

Last Updated:

Applies to

  • SolidFire


  1. How do I go about replacing a SolidFire Drive? 
  • Contact SolidFire Technical Support.
  • SolidFire will supply replacement drives upon any drive failure. It is recommended to have one spare drive per every five nodes. 
  1. Can I be responsible for destroying my own failed drives under SolidFire's drive replacement policy? 
  • Yes, however there is an additional cost that comes along with drive replacement. 
  1. Does SolidFire do anything special to prevent premature wear and help drive endurance? 
  • Yes - SolidFire works directly with SSD manufacturers to provide
    • write endurance internally 
    • sequentially writing the whole SSD 
    • performing periodic "Garbage Collection" to more evenly "wear" across the whole of the SSD.
  • SolidFire's algorithm provides advances on top of manufacturer's wear leveling to exceed the typical manufacture's failure rates.
  1. Does SolidFire allow for on-site spares of drives? 
  • Yes - Customer must purchase onsite spares.
  1. Can I use my own SSD drives within a SolidFire node/cluster? 
  • No - SolidFire's architecture allows only for specific drive sizes and manufacturers.
  1. How do I know how full a drive is?
  • SolidFire's UI and API calls allow a user to poll a given drive for drive utilization. eg.)

This will display something like the following,

7. Does SolidFire do predictive drive failure? 

  • No - Given SolidFire's architecture, it is best to let a component fail completely versus trying to prevent the failure.
