An Efficient Access Forwarding Method Based On Caches On Storage Nodes

Abstract

In this paper, we discuss access forwarding schemes for the replication that achieve balanced access load distribution for data replicas on multiple storage nodes. In

An Experimental Evaluation of the Adaptive Replica-assisted Migration for Parallel Storage Systems

“…We also use replicas for access services, forwarding partial accesses of primary data to replicas. Using replicas not only with migration but also with regular services is beyond the scope of this paper, although we discussed the usage in [5] An advantage of our method is that systems can migrate moderate amount of data even if the source node already becomes hot spot.…”

Comparison of replica assisting and speed adjustment for service-aware horizontal data migration on autonomous disks

“…Access forwarding to nodes storing replicas decreases the hit ratios of cache memory on each storage node because both the primary and replica data of other nodes may be stored in the same cache and will compete for cache space. In this paper, we use a method for choosing forwarded accesses that uses the hit ratios of each cache to estimate the popularity of data at low cost [7]. It helps the replication to use the limited cache space efficiently if accesses for data in less demand are forwarded.…”
