Systems and methods for exchanging runtime functionalities between software stacks

A system architecture comprising:

• a data storage medium;
• a host system comprising:
• a first computing element including a first processor to receive a first set of Input/Output (I/O) requests in the host system,
• a host operating system (OS), and
• a host middleware that logically resides between the host OS and an application in the host system, the first computing element to execute a host system task within the host OS;
• and
• a manageability system comprising:
• a second computing element including a second processor to receive a second set of I/O requests in the manageability system,
• a manageability OS, and
• a manageability middleware that logically resides between the manageability OS and an application in the manageability system, the second computing element to execute a manageability task that is delegated away from the host system, wherein the manageability task is executed within the manageability OS;
• wherein the second computing element is to reorder the second set of I/O requests based on the first set of I/O requests;
• the host middleware is to inform the manageability middleware of at least one data file in the data storage medium that the host middleware accesses;
• and
• the manageability middleware is to synchronize with the host middleware so as to concurrently access the at least one data file being accessed by the host middleware.

A method, comprising:

• receiving, in a host system including a host OS, a first set of I/O requests for accessing a shared storage medium to be executed by a first computing element including a first processor, wherein the first computing element executes a host system task within the host OS;
• receiving, in a manageability system including a manageability OS, a second set of I/O requests for accessing the shared storage medium to be executed by a second computing element including a second processor, wherein the second computing element executes a manageability task within the manageability OS, and wherein the second set of I/O requests is independent of the first set of I/O requests;
• and
• reordering the second set of I/O requests based on the first set of I/O requests,
• wherein the host OS includes a host I/O scheduler to provide the first set of I/O requests to the manageability OS, wherein the manageability OS includes a manageability I/O scheduler to set up the second set of I/O requests for accessing the data storage medium and to repeatedly reorder the second set of I/O requests based on the first set of I/O requests provided by the host I/O scheduler.

A non-transitory computer-readable storage medium storing instructions that upon execution cause an arrangement including a host system and a manageability system to:

• receive, in the host system including a host OS, a first set of I/O requests for accessing a shared storage medium to be executed by a first computing element including a first processor, wherein the first computing element executes a host system task within the host OS;
• receive, in the manageability system including a manageability OS, a second set of I/O requests for accessing the shared storage medium to be executed by a second computing element including a second processor, wherein the second computing element executes a manageability task within the manageability OS, and wherein the second set of I/O requests is independent of the first set of I/O requests;
• and
• reorder the second set of I/O requests based on the first set of I/O requests,
• wherein the host OS includes a host I/O scheduler to provide the first set of I/O requests to the manageability OS, wherein the manageability OS includes a manageability I/O scheduler to set up the second set of I/O requests for accessing the data storage medium and to repeatedly reorder the second set of I/O requests based on the first set of I/O requests provided by the host I/O scheduler.
