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

In storage systems, "block-based" storage refers to the storage of data in fixed-sized blocks. Each block is identified by a unique address and can be individually accessed and modified. Block storage is typically used in SAN (Storage Area Network) environments and is well-suited for databases and virtual machine file systems where high performance and low latency are critical. The "X" in the exhibit likely indicates a storage type that offers these characteristics, pointing towards block-based storage.References: Dell Information Storage and Management V5, Types of Storage Systems,Dell Certification Resource

FCIP (Fibre Channel over IP) is utilized to interconnect Fibre Channel SANs over long distances. This technology encapsulates Fibre Channel frames into IP packets, allowing them to be transmitted over IP networks. It is particularly useful for interconnecting local and remote FC SANs over distances greater than 200 km, providing a cost-effective solution for SAN extension.References:

Archive is a type of data protection that is used to move primary data to lower cost storage and helps to enforce compliance requirements. It is a process of moving inactive data that is no longer needed for immediate use to a secondary storage medium. Archive uses data compression and deduplication techniques to reduce storage costs, and can also be used to help meet compliance requirements.
