Selection of fabric-attached storage drives on which to provision drive volumes for realizing logical volume on client computing device within storage area network

A non-transitory computer-readable data storage medium storing computer-executable code that a computing device directly connected to a fabric and running a storage-area network (SAN) manager executes to perform a method comprising:

• receiving a request from an administrator to allocate and mount a logical volume on a client computing device directly connected to the fabric;
• selecting a set of storage drives on which to store data of the logical volume, from storage drives directly connected to the fabric, based on native capabilities, available capacities, and dynamic performance of the storage drives, and taking into account failure domains in which the storage drives of the set are located in satisfaction of the request, wherein each failure domain corresponds to a group of the storage drives such that a failure corresponding to the failure domain causes failure of each storage drive of the group, the method further comprising:
• for each failure sub-domain type of a plurality of failure sub-domain types, preliminarily grouping the storage drives by failure sub-domains corresponding to the failure sub-domain type;
• determining a number of required failure domains from the request;
• combining the failure sub-domains into which the storage drives have been grouped until the storage drives have been grouped into a number of the failure domains equal to the number of required failure domains, taking into account redundancy importance across the failure domains;
• sending a command to each storage drive of the selected set to provision a drive volume;
• and
• sending a command to a SAN software agent on the client computing device to create and mount the logical volume using the drive volumes provisioned on the storage drives of the set.

A storage-area network (SAN) system comprising:

• a plurality of fabric-attachable storage drives directly connected to a fabric, each storage drive of a set of the storage drives to provision and operate a drive volume;
• a client computing device directly connected to the fabric, and that is to execute a SAN software agent to create, mount, and use a logical volume realized by drive volumes of the set of storage drives;
• and
• a SAN manager directly connected to the fabric and that is to manage the drive volumes of the storage drives, to manage the logical volume that the SAN software agent operates, and is to select the set of the storage drives from the storage drives directly connected to the fabric on which the SAN software agent is to create, mount, and use the logical volume on drive volumes provisioned thereon,
• wherein the SAN manager is to select the set of the storage drives taking into account failure domains in which the storage drives are located, by preliminarily grouping the storage drives by failure domains in which the storage drives are located, determining a number of required failure domains from the request, and combining the failure domains into which the storage drives have been grouped until the storage drives have been grouped into a number of the failure domains equal to the number of required failure domains.
