چکیده

In this paper, we compare the performance of SBOD and MBOD architectures for storage systems using a command profile based on the Storage Performance Council (SPC-1) Benchmark. The performance comparisons include changes in the strip size, in the number of disks and in the intra-enclosure transmission rate (2Gbps and 4Gbps). We show that performance is maximised with 16kbyte strips and that SBOD performance is up to 120% better than MBOD for large strips; the MBOD becoming bandwidth limited at 2Gbps. We also show that an SBOD with an intra-enclosure transmission rate of 2Gbps matches the performance achievable by 4Gbps MBOD/SBOD when loaded with SPC-1 traffic.

IOmeter Performance Comparison of SBOD and MBOD

In this paper, the performance of the emerging Switched Bunch Of Disks (SBOD) RAID architecture is compared to the more traditional Managed Bunch Of Disks (MBOD) using both analytical and simulation models. The benchmark used for this comparison is the conventional IOmeter that enables Throughput and IOPS of these systems to be compared. The SBOD configuration that maximises its performance is ...

Work in Progress: On The Scalability of Storage Sub-System Back-end Network

The aim of this on-going work is to study the scalability of the back-end network of storage subsystems in terms of the number of disks that can be linked to the network. It is well known that without considering the limitation of back-end network, increasing the number of disks in a RAID based storage system will increase the parallelism, and so can lead to a higher performance. Moreover, to s...

Sulfonated Porous Carbon (SPC): An efficient and recyclable solid acid catalyst for one-pot three-component synthesis of 2,3-dihydroquinazolin-4(1H)-ones under solvent-free conditions

A simple and efficient procedure has been developed for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones derivatives under solvent-free conditions. This method uses the condensation of isatoic anhydride, aldehydes, and amines in the presence of a catalytic amount Sulfonated Porous Carbon (SPC). One of the important advantages of the new method is that the SPC could be recycled and reused.

Earth Pressure behind an Integral Bridge Abutment and Comparison with that behind a Conventional Bridge Abutment under Traffic Loads

 Integral bridges are gaining increased popularity because of both economic and fast construction associated with the omission of bearing supports and expansion joints. In the present study the cyclic earth pressure behind integral bridge abutments under traffic surcharges are investigated and compared with that induced behind the abutment of  conventional bridges (with isolated deck and abutme...
