A technique for partially offloading, from a main cache in a storage server, the storage of cache tags for data blocks in a victim cache of the storage server, is described. The technique includes storing, in the main cache, a first subset of the cache tag information for each of the data blocks, and storing, in a victim cache of the storage server, a second subset of the cache tag information for each of the data blocks. This technique avoids the need to store the second subset of the cache tag information in the main cache.
