Intel RMS25KB080 Manual Do Utilizador
Is an Entry or Mainstream RAID Module right for your application?
RAID is pertinent to both data protection and application performance, thus it is important to select the right product for your needs.
The RMS25KB080/040 is an entry-level product that offers exceptional value and may be perfect for mirroring a small number of drives
or for connecting to a bunch of disks using JBOD mode. However, it does not offer all of the features or the performance of Intel’s
mainstream product line. The following table highlights some of the differences between the three key categories of RAID products.
