Methods for managing storage operations for multiple hosts coupled to dual-port solid-state disks and devices thereof

A computing device, comprising:

• a memory containing machine readable media comprising machine executable code having stored thereon instructions for managing storage operations directed to storage devices coupled to multiple hosts;
• and
• a processor coupled to the memory, the processor configured to execute the machine executable code to cause the processor to:
• identify a first physical address mapped to a first logical address in a cached zoned namespace (ZNS) mapping table, wherein the first logical address is extracted from a received request to read at least a first portion of a first file;
• retrieve context metadata comprising a checksum based on the identified first physical address;
• determine when the checksum is valid based on a comparison of at least a portion of the checksum to identification information extracted from the received request and associated with the first portion of the first file, and when the determination indicates the checksum is invalid:
• replace at least the first physical address in the cached ZNS mapping table with a second physical address retrieved from an on-disk ZNS mapping table, wherein the second physical address is mapped to the first logical address in the on-disk ZNS mapping table;
• and
• return the first portion of the first file retrieved from a dual-port solid state disk (SSD) using the second physical address in order to service the received request.

A non-transitory machine readable medium having stored thereon instructions for managing storage operations directed to storage devices coupled to multiple hosts, the instructions comprising machine executable code that, when executed by at least one machine, causes the machine to:

• retrieve a checksum based on a first physical address mapped to a logical address in a cached zoned namespace (ZNS) mapping table, wherein the logical address is extracted from a received request to read at least a portion of a file;
• and
• determine when the checksum is valid based on a comparison of the checksum to identification information extracted from the received request and associated with the portion of the file, and when the determination indicates the checksum is invalid:
• retrieve a second physical address from an on-disk ZNS mapping table, wherein the second physical address is mapped to the logical address in the on-disk ZNS mapping table;
• replace the first physical address in the cached ZNS mapping table with the retrieved second physical address;
• retrieve the portion of the file using the second physical address;
• and
• return the retrieved portion of the file in response to the received request.
