Cache management at a computer for a remote storage system

A method of reading from a remote storage system at a computer, the computer comprising hardware platform that includes a memory, a central processing unit (CPU) having a first cache for the memory, and a storage device, the storage device configured to store a second cache for the remote storage system accessible by the computer over a network, the method comprising:

• maintaining, by first software executing on the hardware platform, metadata in the memory for the second cache, the metadata including a table having rows, each of the rows controlling multiple entries in the second cache, each of the rows having a first size, the first size less than or equal to a second size of entries in the first cache;
• issuing, by second software executing on the hardware platform, a read or write transaction for an object managed by the remote storage system, the transaction indicating a first address;
• executing, by the first software in response to the first address, a first operation on the CPU to read a first row of the rows from the memory to a first entry of the entries in first cache;
• executing, by the first software, a second operation on the CPU to search the first row as stored in the first cache for the first address;
• and
• performing, by the first software, the transaction based on a result of the second operation to read or write from the storage device.

A non-transitory computer readable medium comprising instructions to be executed in a computing device to cause the computing device to carry out a method of reading from a remote storage system at a computer, the computer comprising hardware platform that includes a memory, a central processing unit (CPU) having a first cache for the memory, and a storage device, the storage device configured to store a second cache for the remote storage system accessible by the computer over a network, the method comprising:

• maintaining, by first software executing on the hardware platform, metadata in the memory for the second cache, the metadata including a table having rows, each of the rows controlling multiple entries in the second cache, each of the rows having a first size, the first size less than or equal to a second size of entries in the first cache;
• issuing, by second software executing on the hardware platform, a read or write transaction for an object managed by the remote storage system, the transaction indicating a first address;
• executing, by the first software in response to the first address, a first operation on the CPU to read a first row of the rows from the memory to a first entry of the entries in first cache;
• executing, by the first software, a second operation on the CPU to search the first row as stored in the first cache for the first address;
• and
• performing, by the first software, the transaction based on a result of the second operation to read or write from the storage device.
