Deduplication is a well-known method that improves storage efficiency and reduces the cost of storage in corporate data centers [3, 4]. For virtualized data centers, and in particular for virtual desktop infrastructure (VDI), centrally-managed networked storage can greatly reduce the overall data footprint because virtual machine (VM) disk images have largely the same content. Recent work by By...

Since large-scale and data-intensive applications have been widely deployed, there is a growing demand for high-performance storage systems to support data-intensive applications. Compared with traditional storage systems, next-generation systems will embrace dedicated processor to reduce computational load of host machines and will have hybrid combinations of different storage devices. We pres...

fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (vcgs) and rep-pcr dna fingerprinting. nit ...

Phase Change Memory (PCM) presents an architectural challenge: writing to it is slow enough to make attaching it to a CPU’s main memory controller impractical, yet reading from it is so fast that using it in a peripheral storage device would leave much of its performance potential untapped at low command queue depths, throttled by the high latencies of the common peripheral buses and existing d...

Network attached storage devices improve I/O performance by separating control and data paths and eliminating host intervention during data transfer. Devices are attached to a high speed network for data transfer and to a slower network for control messages. Hierarchical mass storage systems use disks to cache the most recently used les and tapes (robotic and manually mounted) to store the bulk...

To address the limitations of OpenNebula storage subsystems, we have designed and developed an extension that is capable of achieving higher I/O throughput than the prior subsystems. The semi-shared storage subsystem uses central and distributed resources at the same time. Virtual machine instances with high availability requirements can run directly from central storage while other virtual mac...

This paper assesses our state of knowledge of physiological processes involved in the relationships between insects and their mermithid nematode parasites. Three major components of the host-parasite relationship(s) are reviewed: effects of mermithids on host physiology, effects of host physiology on mermithids, and the physiology of the nematodes themselves. Mermithids induce an array of chang...

Digital watermark is an active research area that has received a considerable attention in multimedia applications. For most watermark applications, it is often desired to retrieve the embedded information without access to the host data, which is known as blind watermark. Most of previous blind watermark schemes either suffer significantly from host data interference or require expense of stor...

According to the new type of portable PLC programming device adopting the own invention technology, a PLC editor system with ARM microprocessor and μC/OS-II system as the core was constructed. Logic operation instructions with multiple operands and their encodes were designed. The data storage capacity was expanded. A CAN extension protocol was formulated. Two-way chain table was adopted to edi...
