BUILDING SECURE AND REDUNDANT STORAGE FOR FEDERAL, STATE AND LOCAL GOVERNMENTS cont. point of failure. The array is able to do this because the OS is no place in government service that requires one hundred built specifically as a way to use RAID with flash. This solution percent accuracy. RAID-3D uses a series of independent fixes the three major problems that happen when trying to checksums along with dedicated parity to eliminate this shoehorn flash drives into a RAID configuration that they were problem. Any bit errors are instantly detected, healed and not originally designed to run. written around. That same system of parity also eliminates the variable performance some organizations experience with solid state drives. The peaks and valleys in performance are associated By enlisting a Pure with the standard RAID garbage collection mechanisms which tend to get clogged and reduce throughput. RAID-3D looks Storage FlashArray, at this problem like any other point of failure and uses parity to work around all potential bottlenecks. The end result is organizations across consistently fast performance all the time. And last but not least, although flash is much more reliable government can employ than traditional drives due to having no moving parts, drives can still fail for a variety of reasons. Most RAID controllers high security, fast don’t handle flash drive failure very well, but RAID-3D ensures that no two pared drives can fail at the same time. If any drive performance and reliable in the array goes down for any reason, its data is served from a backup location while the OS re-builds and writes around continuous operations. the failing component within minutes. Users never see any performance hit and don’t ever lose data. By enlisting a Pure Storage FlashArray, organizations across government can employ high security, fast performance Called RAID-3D, it’s RAID for pure flash drives. The first thing and reliable continuous operations. Regardless of the RAID-3D does is to eliminate problems associated with bit circumstances, government agencies will know that their errors, device failure and variable performance levels. Starting mission data is protected, efficient and always available. with bit errors, they are the most annoying problem for most organizations trying to use flash with RAID. Flash drives are more vulnerable to returning incorrect data other than what was stored. Normally minor in nature, it nonetheless has © Pure Storage 2014 | 8
