Abstract: In Elastic Optical Networks with Space Division Multiplexing, the dynamic allocation and deallocation of frequency slots can generate spectrum fragmentation, which increases the blocking of ...
A disk error indicating a bad block points out to disk failure. It can happen to HDDs and SSDs and the damage could be hardware or software-related. You’ll notice ...
Decision support queries that scan large indexes can suffer significant degradation in I/O performance due to index fragmentation. DBAs rely on rules of thumb that use index size and fragmentation ...
Abstract: This paper evaluates Spatial Division Multiplexing in Elastic Optical Network (SDM-EON) defragmentation scenarios and applies a combined push-pull and fast-switching defragmentation ...
