A hypervisor is a layer of software that runs directly on top of a physical server and provides a virtualization layer. It allows multiple virtual machines (VMs) to run on the same physical hardware, sharing the underlying resources such as CPU, memory, and storage. The hypervisor isolates the VMs from each other and provides a virtual machine monitor (VMM) that manages the virtual machines' access to physical resources. The VMM is responsible for managing the VMs' creation, configuration, and removal, as well as their access to the physical resources of the host system. T

Serial Attached SCSI (SAS) is a protocol that offers a cost-effective balance between I/O performance and storage capacity, making it ideal for midrange storage applications. SAS devices provide higher data transfer rates and improved scalability compared to SATA while being more affordable than NVMe solutions, which are typically used for high-performance environments.
