Abstract
In at least one embodiment, processing can include receiving, at a first node, a read request directed to a logical address LA owned by a second node. The first node can locally cache content and an address hint corresponding to LA. The first node can issue a request to the second node. The request can include a flag to suppress the second node from returning content stored at the target logical address. The first node can receive a response including an address used to read current content of LA1 from back-end non-volatile storage. The first node can determine whether the address matches the address hint cached on the first node. If the first node determines the address and address hint match, the cached content of LA stored on the first node is valid and can be returned in response to the read as current content stored at LA.
