Data written to the stripes is alternated across each of the drives, as shown in the diagram.</p> -<p><img src="http://localhost:1313/brycematheson.io/img/post_images/raid1.png" alt="RAID" /></p> +<p><img src="http://localhost:1313/img/post_images/raid1.png" alt="RAID" /></p> <p>Although RAID Level 0 uses multiple drives, it is not fault tolerant, which means that if one of the drive fails, all of the data on that drive is lost.</p> <p>RAID Level 1 (mirroring): RAID Level 1 uses disk mirroring. Disk mirroring involves connecting multiple drives in the computer (or server) to the same disk controller card. When data has been requested to write data to the drive, the controller sends that same request to each drive. The same happens for a read request: the data is read twice, once from each drive. By “mirroring” the read/write actions on the primary drive, all the other drives become identical duplicates. If the primary hard drive fails, the other drives take over immediately, without losing any data. This is shown in the diagram below.</p> -<p><img src="http://localhost:1313/brycematheson.io/img/post_images/raid2.png" alt="RAID" /></p> +<p><img src="http://localhost:1313/img/post_images/raid2.png" alt="RAID" /></p> <p>RAID 5 (independent disks with distributed parity): RAID Level 5 distributes parity data (a type of error checking) across all drives, instead of using a separate hard drive to hold the parity error-checking information. Data is always stored on one drive, while its parity information is stored on another drive, as you can see from the diagram below. Distributing parity across other disks simply provides a user with an additional layer of protection from data loss.</p> -<p><img src="http://localhost:1313/brycematheson.io/img/post_images/raid3.png" alt="RAID" /></p> +<p><img src="http://localhost:1313/img/post_images/raid3.png" alt="RAID" /></p> <p>RAID 0 + 1 (high data transfer): RAID 0+1 is a nested-level RAID. It acts as a mirrored array whose segments are RAID 0 arrays. RAID 0+1 can achieve high data transfer rates because there are multiple strip segments. RAID 0+1 is shown below. With nested RAIDs, the elements can either be individual disks, or entire RAIDs. This is my preferred RAID configuration, as it provides redundancy for protection in case one of the drives fails, but it also increase read/write input/output. The only downside to this configuration is that you have to purchase four hard drives as a minimum. Start getting into solid-state drives, and you’re easily looking at $600.</p> -<p><img src="http://localhost:1313/brycematheson.io/img/post_images/raid4.png" alt="RAID" /></p> +<p><img src="http://localhost:1313/img/post_images/raid4.png" alt="RAID" /></p> <table> <tr> @@ -280,7 +277,7 @@ <div class="entry-links"></div> </article> <div class="share-icons-body"> - <a href="http://www.twitter.com/share?url=http%3a%2f%2flocalhost%3a1313%2fbrycematheson.io%2fpost%2f2014-07-16-understanding-raid%2f" target="_blank"> + <a href="http://www.twitter.com/share?url=http%3a%2f%2flocalhost%3a1313%2fpost%2f2014-07-16-understanding-raid%2f" target="_blank"> <svg version="1.1" id="Capa_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 612 612" style="enable-background:new 0 0 612 612;" xml:space="preserve"> <g> <g> @@ -297,7 +294,7 @@ S459.64,584.182,306,584.182S27.818,459.64,27.818,306z"/> </g> </svg></a> - <a href="http://plus.google.com/share?url=http%3a%2f%2flocalhost%3a1313%2fbrycematheson.io%2fpost%2f2014-07-16-understanding-raid%2f" target="_blank"> + <a href="http://plus.google.com/share?url=http%3a%2f%2flocalhost%3a1313%2fpost%2f2014-07-16-understanding-raid%2f" target="_blank"> <svg version="1.1" id="Capa_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 612 612" style="enable-background:new 0 0 612 612;" xml:space="preserve"> <g> <g> @@ -318,7 +315,7 @@ S459.64,584.182,306,584.182S27.818,459.64,27.818,306z"/> </g> </svg></a> - <a href="https://www.facebook.com/sharer/sharer.php?u=http%3a%2f%2flocalhost%3a1313%2fbrycematheson.io%2fpost%2f2014-07-16-understanding-raid%2f" target="_blank"> + <a href="https://www.facebook.com/sharer/sharer.php?u=http%3a%2f%2flocalhost%3a1313%2fpost%2f2014-07-16-understanding-raid%2f" target="_blank"> <svg version="1.1" id="Capa_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 612 612" style="enable-background:new 0 0 612 612;" xml:space="preserve"> <g> @@ -335,28 +332,23 @@ <div class="clearfix"></div> <figure class="author-bio"> <img class="bio-image" src="../../img/avatar.jpg" /> -<figcaption class="bio-text">Bryce Matheson works as a Windows Systems Administrator for a small IT company based out of Idaho Falls.
