A local disk interface, usually slower than NVMe or SAS. vSAN ESA cannot use it since that architecture requires NVMe.
Also called Serial ATA.
In the Ultra Transcenders books
Each book explains SATA in context, with comparison tables and the common traps.
Terms in this definition
- LSDOU
The sequence in which Group Policy is processed: the local policy first, followed by site, domain and organisational unit policies. The nearest, last-processed setting takes effect unless Enforced or Block Inheritance alters that.
- NVMe
Flash Optimized Azure Managed Redis keeps keys and hot values in memory while moving colder values, roughly 80 percent of capacity, onto this high-speed flash storage.
- Serial Attached SCSI
SAS for short: the interface typically found on server drives and shared JBOD enclosures; Storage Spaces handles it alongside NVMe and SATA. Don't mix it up with Azure's shared access signatures.
- vSAN ESA
Newer vSAN design built for NVMe, with one tier and storage pools rather than disk groups. OSA is the older design, using two tiers.
