Intel RMS25KB040 ユーザーズマニュアル

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.

Performance Factors

Utilizes the Intel® Xeon® processor 
and system memory and thus will 
be affected by the server load

 Includes an I/O processor (IOP) for 
true hardware RAID 0, 1, 1E, but 
the IOP is not powerful enough to 
handle parity calculations

Includes a RAID-on-Chip (ROC) 
processor and up to 1GB embedded 
cache for superior performance

Data Protection Factors

Limited diagnostics, tied tightly to 
OS, and long rebuild times
