I have tried to find out why there is BSAS & SAS disk types when creating an aggregate to no avail. What is BSAS?
Serial Attached SCSI (SAS)
Bridged SAS (BSAS) - SATA drives
BSAS stands for Bridged SAS.
When you see that on a NetApp system it means you have SATA disks in a SAS enclosure.
Based on current product offerings this would be a DS4243 disk shelf.
Are you seeing both BSAS and SAS disk types in the same aggregate?
I didn’t think that was possible.
Also refer to the below document
This show the mix and match of certain types of disks in the same aggregate
Im not that familiar with netapp. I only know the basics. Anyway I was reading on this forum below:
and you asked "Are you seeing both BSAS and SAS disk types in the same aggregate?"
I do see this and i was trying to figure out which Netapp has what. I was told one has Sata (BSAS) and another has SAS. I see both types in both Netapps. Why is this? Also would you know or know of any documentation on how to learn your current Netapp configuration. What i mean by that is how they are connected to the network and to eachother? these netapps are stored in a Data Center hundreds of miles away. I understand these might be stupid questions but i figure i can learn more about SAN storage. I ve attached screenshots of each netapp.
Is it posted anywhere what the drive specs are on BSAS? I am interested to know what kind of IO it can support.
I don't know of anything posted. BSAS are basically the Sam as 7200 sata drives,
Richard is correct..that BSAS are the same as SATA and can be used as Tier 2 low performing applications or backup filers.
