Can I mix SAS and SATA drives?
While you can use a combination of SAS and SATA hard drives running on the same controller, you cannot mix them in the same array. This means that if the hard drives are configured together in any sort of array, you would need to replace that SAS hard drive with an identical SAS hard drive.
How many HDD can be connected using SAS?
An eight-port SAS controller (approximately $600) can support a large number of drives. With only internal connectors, an eight-port controller can connect up to eight drives directly, or more if expanders are used. Using external connectors, an eight- port controller can connect up to 128 drives by scaling with JBODs.
What is an SAS hard drive?
In computing, Serial Attached SCSI (SAS) is a point-to-point serial protocol that moves data to and from computer-storage devices such as hard disk drives and tape drives. SAS offers optional compatibility with Serial ATA (SATA), versions 2 and later.
Can you mix SSD with RAID 5 HDD?
Do not mix SSDs and HDDs within the same disk array. A disk array must only contain SSDs or HDDs. An HDD hot-spare device replaces a failed device for an HDD disk array. It is preferred that SSDs be protected by RAID 5, RAID 6, RAID 10, or by system mirroring.
How much faster is SAS than SATA?
SAS, or Serial Attached SCSI, is a faster and historically more expensive interface. Because SAS drives are able to rotate so much faster (up to 15K RPM) than SATA drives (typically 7.2K RPM), seek times may be substantially faster by more than 2 times.
Can a SAS drive be used with a SATA drive?
The Perc Controller configuration you have shown would be fine. You can mix SAS and SATA drives on the controller, it can handle both. You can have SAS arrays and SATA arrays present on the same controller. You can NOT have SAS and SATA drives present in the SAME array though.
Can a Dell controller mix SATA and SAS?
Hello. Dell controllers including the H200 do not supported mixing either SAS, SATA or SSDs together in the same array. They can however, each separately constitute a Virtual Disk on the same controller. Consider replacing the failed drive another SAS drive of same or higher capacity.
Can you replace a SAS drive with a larger one?
I was hoping to replace 1 with a larger drive and let it re-mirror. Then replace the other 120GB SAS drive with a larger one. Then when it is done, you go into Disk Manage on Windows 2012R2 or higher and you can extend the C: drive to see the additional space.
Why do I need a Seagate SAS controller?
There are many factors to take into consideration, including where and how the unit will be used, which applications will be used, and what the necessary requirements are, as well the capacity levels, performance, reliability, or speed needed.
