There must be an even number of drives for raid.
Raid 10(10) and raid 1 are the most costly fault tolerance methods because they require 50 percent of the drive capacity to store the redundant data.
Supported Local Raid Levels, rAID 0, striping (No Fault Tolerance) : Offers the greatest capacity and performance without data protection.Minimum number of drives per raid 10 group: 4, single drive cost: Cost per TB usable bmi calculator kg woman : Total cost: To calculate, enter: Number of drives per raid group - the number of drives in a single raid 10 group (minimum 4 drives, must.Best applications for using Network raid-5 volumes include applications with mostly read, sequential workloads, such as file shares and archiving.Such applications include databases, email, and server virtualization.Raid 10 requires minimum of 4 drives, and the number of drives must be even.Network raid : The redundancy system which can be configured across multiple boxes.
If you select this option, you will experience data loss if a hard drive that holds the data fails.Network Raid : raid-10, network raid-10 data is striped and mirrored across two storage systems.Usable capacity is N-1 where N is the number of physical drives in the logical array.Note: 1 TB 1000 GB and GiB All rights reserved.Nraid10 : 10,6TB, nraid101 : 7TB, nraid102 : 5,3TB.Each data block is written to all drives in the set.Basic Set-up : A Multi-Site SAN, with 4 HP P4500 nodes of 12x600GB.Raid 01 is a combination of raid 0 with raid 1 - data blocks are mirrored across two identical raid 0 groups.Network raid-101 data is striped and mirrored across three or more storage systems.The system continues operating with a slightly reduced performance until you replace the failed drive.One who knows deeper, does better.
Raid 1 mirrors the contents of one hard drive in the array onto another.
Raid 6 : Offers the best data protection and is an extension of raid.
