    DAS (Direct-Attached Storage) and Rack Servers are two different types of storage systems.

    DAS Server is a type of storage system that is directly connected to a single host computer. DAS devices are physically connected to the computer using a cable such as SATA, SCSI, or SAS, and they appear as a local disk to the operating system. DAS is a simple, cost-effective storage solution that is well suited for small and medium-sized businesses and is typically used for file and application storage.

    Rack servers, on the other hand, are specialized computer systems designed to be mounted in a rack. Rack servers are used in data centers and are typically used to host multiple virtual machines or applications. They are designed to be highly available and scalable, and they offer a higher level of performance and reliability compared to DAS systems. Rack servers are typically connected to a network-attached storage (NAS) or storage area network (SAN) for centralized storage.

    In summary, the main difference between DAS and rack servers is the way they are connected to the storage and their intended use cases. DAS is a simple, direct-attached storage solution, while rack servers are designed for more complex, multi-user environments where centralized storage is required.
