hard drive - SAS-3 vs SAS-2 HDDs - Server Fault
May 28, 2015 · What are the main differences between SAS-3 and SAS-2 HDDs? Are there performance differences? Suppose we are talking of 10k rpm disks, ~1 TB, in both cases. Regards,
sata - Beginner SAS and SAS2 speed expectations - Server Fault
Dec 11, 2013 · We have one SAS backplane, without SAS expander, with 8 HDDs and we connect it to the motherboard with 2 SFF-8087 to 4 sas/sata cables. The motherboard supports SAS2 and the SSD supports SAS2. How...
SAS / SAS2..... compatible? - Server Fault
Is it theoretically possible to mix a SAS2 controller with a SAS expander? We just happen to have this scenario - the expander (which works fine with an older SAS adaptec controller) is not found and Adaptec (which handle the new 71605Q raid controller) insists on telling me this is because the expander is a SA expander and not a SAS2 expander.
Are 6Gb/s SAS drives compatible with 3Gb/s SAS interfaces?
Aug 15, 2011 · Are SAS 3Gb/s controllers (SAS1) forward compatible with newer SAS2 drives specified at 6Gb/s? The controller I have in mind is an LSI SAS1064. I know that SAS2 controllers are backwards compatible with SAS devices. I found some information in this thread:
performance - If I connect a SATA3 6Gbps SSD to a SAS2 6Gbps …
May 31, 2019 · I have 2 SATA3 SSDs in my server, which are currently connected to SATA2 ports. If I wanted to get SATA3 speeds out of them instead, could I buy a SAS2 HBA and use an SFF-8087 to SATA breakout cable to get 6Gbps speeds out of it (since SAS2 is Gbps) or would I need a SAS3 or SATA3 card to get those speeds?
SAS-2 6Gbps Maximum Disk Capacity - Server Fault
Mar 31, 2016 · So I think this should be a simple enough question but my google-fu is not turning up an answer. I am wondering what the maximum size a single physical disk can be under the SAS-2 6Gbps spec.
Is SAS3 backwards compatible with an SAS 1 controller?
May 24, 2021 · ), and it appears SAS3 is backwards compatible with SAS2, but I have not yet seen any confirmation that SAS3 is backwards compatible all the way back to SAS 1. With the right cable, would such a drive be compatible with an older SAS controller like in my motherboard, in the way that USB 3.0 can work with USB 1.0?
raid - SAS Expanders vs Direct Attached (SAS)? - Server Fault
Regarding the theoretical performance: For the 24 drive backplane, you should have (SAS2) 6 gbit x 4 = 24 Gbit what is 1 Gbit per disk. Using the same math, you should get 2 Gbit per disk with the other backplane. Now, 1Gbit per disk stands for... 80 MB/s ? So, 2Gbit would be more than enough for the disk to become the bottleneck. So:
Understanding SAS transfer speeds - Server Fault
Dec 18, 2014 · I've been tasked with building some large storage and i'm first working to expand my SAS knowledge. As i consider transfer bottlenecks and SAS speeds, i can't help but wonder how 12 Gb/s SAS equat...
