Drive Planning
In a Hadoop-like environment, a single drive is used as the data drive. Therefore, there are two options: JBOD and single-drive RAID 0.
If the LSI SAS3108, LSI SAS3408, or LSI SAS3508 RAID controller card is used, you are advised to create a single-drive RAID 0 group to fully utilize the cache of the RAID controller card (the cache of the LSI SAS3108 RAID controller card is 2 GB) and improve the read/write speed.
