SAS FLASH Drives
Hi All,
I know about SAS drive and FLASH drive. What is SAS FLASH?
In our VNX5500 have two "SAS Flash" drives which located next to the vault area (0_0_4 and 0_0_5) configured in RAID-1 for FAST cache.
What about "SAS Flash"? is there any difference between Flash and SAS Flash?
I understand Flash drive supports 3500 IOPS and how many IOPS "SAS Flash" will support?
Please suggest.
Regards,
Dhakshinamoorthy Balasubramanian

Hi,
dont worry wether it says „SAS Flash” or “SATA Flash” drive.
It is a regular SLC flash drive.

Well – there were some flash drives in VNX1 that showed as „SATA flash” – but that’s not important – they have the same performance

SAS is how the drive interfaces with the storage system. Other examples would be Parallel SCSI, SATA or FC-AL. All the drives in the VNX are SAS.
