Low-Cost and Easy-to-Use Hardware RAID 5 Solutions
[ Source: ACCUSYS ]
January 2008-
This paper from ACCUSYS discusses that RAID (Redundant Array of Independent Disks) technology has been proved as the best technology to protect large-volume data while provide excellent performance. There have been a variety of implementations of RAID, and various products have been delivered to the market. Among them, the most widely adopted RAID technology is hardware RAID 5, which offers the good performance with superior reliability. However, due to its nature of complexity in algorithms, hardware ...
3ware 9550SX SATA II RAID Controller Optimized Performance Report for Windows and Linux
[ Source: AMCC ]
January 2008-
The 3ware 9550SX controller performs exceptionally well when the file system provides high levels of sequential I/O. Performance tuning characteristics can vary with the number of attached drives and the relative size of data blocks. Performance typically scales with the addition of drives to an array. Read and write performance improves when scaling from one to 12 drives for write operations, and from one to 16 drives for read operations. Write performance is affected by several ...
Five Fatal Myths of Data Backup
[ Source: AbilityCRM ]
February 2008-
Data loss can cause catastrophic problems to businesses. When not fatal, it can certainly be costly, time-consuming, and stressful. The best protection against data loss is to backup the data. Yet the process of data backup can be confusing and is often misunderstood. This paper addresses the most common fatal myths that our support desk encounters on a daily basis.
Hardware RAID Vs. Software RAID: Which Implementation Is Best for My Application?
[ Source: Adaptec ]
January 2008-
This paper from Adaptec shows the benefits that hardware RAID offers over software RAID implementations. Advances in silicon technology are allowing for integration of the processors required for hardware RAID into single chip solutions and soon into commodity server chipsets, which will shrink the implementation cost. This reduced cost will enable a broader deployment of hardware RAID solutions into lower-priced servers, making them available to more users. Currently, new levels of data protection and manageability ...
Measuring the True Performance of Today's SATA and SAS RAID Controllers
[ Source: Adaptec ]
January 2008-
One of the difficulties of choosing a RAID controller is that individuals can’t really know how it will perform in the environment until they already have it installed. All too often, RAID vendors quote irrelevant measurements to demonstrate the maximum performance of their RAID controller, and don’t demonstrate how the RAID controller will hold up under a real world application environment. Performance measurements in the IT world can be defined in many different ...
The Move to PCI Express in Next Generation Systems
[ Source: Alliance Systems ]
January 2008-
This paper published by Alliance System describes the next generation Input/Output (I/O) interconnect standard for the PC industry is PCI Express and PICMG 1.3 specifications. PCI Express is a dual-transaction protocol that prioritizes packets to more specific targets, enabling a higher performance interface. But, as platforms change to incorporate these new PCI standards, they are virtually eliminating space for high-end telephony boards. This paper represent the next major leap in PC interconnect I/O ...
The Time Has Come to Switch to RAID 10
[ Source: Alliance Systems ]
January 2008-
RAID (Redundant Array of Independent Disks) is the standard for combining multiple independent hard drives to form one large logical array. Each RAID level represents very different trade-offs in terms of cost, availability, and performance. Applications that can benefit from RAID 10 are ones where both high performance and reliability are paramount. RAID 5 is still the best choice for pure redundancy when using four drives or less, but when performance is a key to the success ...
Performance Analysis of IOP Processor (XScale) for SAN/NAS Application
[ Source: Arizona State University ]
January 2008-
Effectively managing vast amounts of storage has created the need for a robust, scalable and manageable external storage solution. The storage-area network (SAN) and network attached storage (NAS) were designed to meet these needs. In NAS and SAN environment, data is transferred from a server to the storage subsystem, and IOP subsystem memory is used as cache to store data temporarily before writing to the storage devices. This paper studies the current performance capabilities and ...
Storage-Based File System Integrity Checker

January 2008-
This paper presented by Association for Computing Machinery presents storage based Intrusion Detection System (IDS) which uses time and space efficient point-in-time copy and performs file system integrity checks to detect intrusions. The storage system software is enhanced to keep track of modified blocks such that the file system scan can be performed more efficiently. Furthermore, when an intrusion occur a recent undamaged copy of the storage is used to recover the compromised data.
Broadcast Services Enabled by Local Storage and Connectivity

January 2008-
Local hard disks are changing the way in which users consume audio and video content. Technologies that were previously associated with the computer domain are being investigated to offer rich network connectivity to digital set top boxes, allowing users to simply pass media of different types from home to home. These technologies provide broadcasters and other parties many opportunities for new services and many challenges. This paper introduces some of the technologies described in the ...
