EIDE Disk Arrays and Its Implement
نویسنده
چکیده
Along with the information high-speed development, RAID, which has large capacity, high availability, and high performance, has played an important role in storage system. Comparison with SCSI disk drive, the body of EIDE disk drive is similar to SCSI’s, but for long time, EIDE disk drive performance is lower than SCSI disk drive’s. Recently,an EIDE drive is rapidly developed. New EIDE drive almost offers similar performance to SCSI’s. At the same time, PC motherboard provides a lot of technology supports. Thus, it is possible that RAID is consisted of EIDE disk drives. Although many technologies and methods of SCSI RAID can continue to be used in EIDE RAID, there are other problems required to solve in EIDE RAID. The research work is processing. In this paper, for the first time, we propose a kind of architecture based on system integration, and a method of protocol conversion between SCSI and ATA. They should support a host to send an I/O request from a SCSI adapter to an EIDE RAID. They also support heterogeneous channel disk arrays. The test result is the performance and price ratio of EIDE RAID is better than SCSI disk arrays’.

Redundant Arrays of IDE Drives
We report tests of redundant arrays of IDE disk drives for use in offline high energy physics data analysis. Parts costs of total systems using commodity EIDE disks are now at the $4000 per Terabyte level. Disk storage prices have now decreased to the point where they equal the cost per Terabyte of Storage Technology tape silos. The disks, however, offer far better granularity; even small insti...
متن کاملWorking with Arrays of Inexpensive EIDE Disk Drives
In today’s marketplace, the cost per Terabyte of disks with EIDE interfaces is about a third that of disks with SCSI. Hence, three times as many particle physics events could be put online with EIDE. The modern EIDE interface includes many of the performance features that appeared earlier in SCSI. EIDE bus speeds approach 33 Megabytes/s and need only be shared between two disks rather than seve...

High-energy physics experiments are currently recording large amounts of data and in a few years will be recording prodigious quantities of data. New methods must be developed to handle this data and make analysis at universities possible. Grid Computing is one method; however, the data must be cached at the various Grid nodes. We examine some storage techniques that exploit recent developments...

متن کاملA Modular, Analytical Throughput Model for Modern Disk Arrays
Enterprise storage systems depend on disk arrays for their capacity and availability needs. To design and maintain storage systems that efficiently satisfy evolving requirements, it is critical to be able to evaluate configuration alternatives without having to physically implement them. In this paper, we describe an analytical model to predict disk array throughput, based on a hierarchical dec...
