Storage system and a method for application aware processing
A method for accessing a storage system, the method may include receiving a block call, from a processor that executes an application and by a storage engine of a computer that is coupled to a storage system; generating, by the storage engine and based on the block call, a key value call; and sending the key value call to a key value frontend of the storage system.
1. A method for accessing a storage system, the method comprises:
receiving a block call, from a processor that executes an application and by a storage engine of a computer that is coupled to a storage system;
determining whether to convert the block call to a key value call based on a state of the storage system;
generating, by the storage engine and based on the block call, a key value call; and
sending the key value call to a key value frontend of the storage system, wherein the state of the storage system comprises a load imposed on the key value frontend of the storage system and on a block frontend of the storage system.
2. The method according to claim 1 wherein the generating comprises generating storage processing hints that are included in the key value call.
3. The method according to claim 2 wherein the storage processing hints are indicative of a priority of the key value call.
4. The method according to claim 2 wherein the storage processing hints are indicative of whether to respond to the key value call by executing a background process.
5. The method according to claim 2 wherein the storage processing hints are application-level semantic hints.
6. The method according to claim 1 further comprising sending the block call to a block frontend of the storage system.
7. The method according to claim 6 comprising sending, in parallel, the block call, and the key value call.
8. The method according to claim 1 wherein the generating of the key value call comprises converting the block call to the key value call.
9. The method according to claim 1 wherein block call is associated with application data; and wherein the key value call is related to application metadata.
10. The method according to claim 1 comprises treating in a different manner block calls and key value calls.
11. The method according to claim 10 comprising associating different levels of service to block calls and to the key value calls.
12. A non-transitory computer readable medium that stores instructions that once executed by a computer causes the computer to execute the steps of:
receiving a block call, from a processor that executes an application and by a storage engine of a computer that is coupled to a storage system;
determining whether to convert the block call to a key value call based on a state of the storage system;
generating, by the storage engine and based on the block call, a key value call; and
sending the key value call to a key value frontend of the storage system, wherein the state of the storage system comprises a load imposed on the key value frontend of the storage system and on a block frontend of the storage system.
13. The non-transitory computer readable medium according to claim 12 wherein the generating comprises generating storage processing hints that are included in the key value call.
14. The non-transitory computer readable medium according to claim 13 wherein the storage processing hints are indicative of a priority of the key value call.
15. The non-transitory computer readable medium according to claim 13 wherein the storage processing hints are indicative of whether to respond to the key value call by executing a background process.
16. The non-transitory computer readable medium according to claim 13 wherein the storage processing hints are application-level semantic hints.
17. The non-transitory computer readable medium according to claim 12 that stores instructions for sending the block call to a block frontend of the storage system.
18. The non-transitory computer readable medium according to claim 17 that stores instructions for sending, in parallel, the block call, and the key value call.
19. A computer that comprises multiple circuits that comprise a processor, wherein the multiple circuits are configured to execute the steps of receiving a block call, from the processor when the processor executes an application and by a storage engine of a computer that is coupled to a storage system; determining whether to convert the block call to a key value call based on a state of the storage system; generating, by the storage engine and based on the block call, a key value call; and sending the key value call to a key value frontend of the storage system, wherein the state of the storage system comprises a load imposed on the key value frontend of the storage system and on a block frontend of the storage system.
