Deconstructing Network Attached Storage systems
Network Attached Storage (NAS) has been gaining general acceptance, because it can be managed easily and files shared among many clients, which run different operating systems. The advent of Gigabit Ethernet and high speed transport protocols further facilitates the wide adoption of NAS. A distinct feature of NAS is that NAS involves both network I/O and file I/O. This paper analyzes the layere...
متن کاملDetector Arrays for Digital Holographic Storage Applications
This chapter discusses detectors for holographic data storage applications. While it may be possible to use a single detector or linear array of detectors, the focus here is on 2-D arrays of pixels. There are many considerations for the detector array when designing a complete system that arise from the intimate relationship between the holographic storage system, optical readout technique and ...
متن کاملInducing Models of Black-Box Storage Arrays
This paper applies statistical model-induction techniques to the problem of forecasting response times in storage systems. Our work differs from prior research in several ways: we regard storage systems as black boxes; we automatically induce models rather than constructing them from detailed expert knowledge; we use lightweight passive observations, rather than extensive controlled experiments...
متن کاملDesign Of Provably Correct Storage Arrays
In this paper we describe a hardware design method for memory and register arrays that allows the application of formal equivalence checking for comparing a high-level register transfer level (RTL) specification with a low-level transistor implementation. Equivalence checking is increasingly applied in practical design flows to verify regular logic components. However, because of their specific...
متن کاملUsing MEMS-Based Storage in Disk Arrays
Current disk arrays, the basic building blocks of highperformance storage systems, are built around two memory technologies: magnetic disk drives, and non-volatile DRAM caches. Disk latencies are higher by six orders of magnitude than non-volatile DRAM access times, but cache costs over 1000 times more per byte. A new storage technology based on microelectromechanical systems (MEMS) will soon o...
