Why is configuring an iSCSI LUN on a NAS the best design choice for vDisk storage?

While potentially less expensive than a full SAN, a dedicated NAS with iSCSI capabilities may not always be the absolute least expensive option compared to simpler storage solutions.

While NAS devices can offer some scalability and resilience, a dedicated SAN or more advanced clustered storage solutions typically provide higher levels of these attributes for critical vDisk storage.

Configuring and managing iSCSI LUNs on a NAS still requires specific knowledge and administrative tasks, which might not be the absolute least amount of overhead compared to simpler file shares.

A NAS is an integrated appliance that combines storage hardware with an operating system and network connectivity in a single unit. Utilizing iSCSI on a NAS allows for block-level storage access from a compact device, effectively reducing the physical space, cabling, and power requirements compared to separate server and storage systems.
