Hardware RAID vs. Software RAID

To make informed disk array purchase decisions, it is important to look beyond a discussion of the different RAID levels and also understand the differences between software and hardware-based RAID implementations. Software-based arrays are typically the least expensive to implement. Conversely, the true cost of this implementation can increase dramatically...

Testing your software RAID: Be prepared

Managing Software RaidHi,I tried this out and it does work perfectly.I was just surprised with how long it takes to rebuild a raid array after a disk failure.On my test PC, although NOT really optimized (i.e. both disks were on the same ATA channel: Master & Slave) it took close...

Testing your software RAID: Be prepared

After successfully setting up a Software RAID mirror, it's important to recognise a drive failure and know how to recover from it. Most often a failing drive will fill your /var/log/messages file with SCSI errors like these: kernel: sidisk I/O error: dev 08:02, sector 1790260 ...

Software RAID for Ubuntu LTS: Better to be safe than sorry

I recently experienced a disk failure on a HP DL320 G3 server. The cheap, high capacity SATA disks were not in a RAID-1 mirror because the server's FakeRAID did not support the flavour of Linux in use. Luckily, important data and configuration files were safely backed up, but it's still...

Software RAID for Ubuntu LTS: Better to be safe than sorry

This article is soooo cool!I was thnking of doing something similar with Linux at home. I did this on Windows 2000 years ago and it worked quite well. I did it with 4 drives then with Disk Management. There's lot's of documentation on how to do it under Linux. I...

Hardware/Software RAID Management

Hello,I have a mix of software and hardware RAID configurations using both Adaptec and Intel RAID Systems. Adaptec has software that will E-mail you when a HDD fails and the RAID requires a new HDD. Intel's software will not E-mail you if a harddrive dies. Is there...

Designing RAID Adapters to Work With Windows

Much confusion exists about how Microsoft Windows operating systems use storage devices such as RAID adapters. This paper discusses how to design RAID hardware and drivers so that they work well with Windows and meet the requirements of the Windows Logo Program. In this paper, a hardware RAID implementation is...

Hardware RAID Vs. Software RAID: Which Implementation Is Best for My Application?

In the last couple of years, RAID Redundant Array of Independent Disks technology has grown from a server option to a data protection requirement. The first implementations of RAID in 1990 were very expensive controller boards with high-performance I/O processors that were as powerful as the host CPU. At that...

Configuring and Managing Software RAID With Red Hat Enterprise Linux 3

Hardware-based RAID controllers have long been the preferred method for implementing RAID storage because they offload the management of RAID arrays onto a separate processor, freeing precious system CPU cycles for other tasks. However, the price/performance ratio of CPUs has decreased, making software-based RAID a viable alternative for system administrators...

Understand 'single digit' RAID levels
