This tool will help you calculate how much space will be available in a specific RAID configuration based on the number of drives and their size. It will also provide information about required supported storage capacity to make such configuration work.
Please note that each Open-E DSS V6 and Open-E DSS V7 license supports a certain maximum available storage space that can be utilized. With the "Unlimited" license there are no limitations set on how much storage space can be used, also if the combined Storage Licenses exceed 48TB it is treated as "Unlimited" version as well.
1) Available Space in shown in 2^40 bytes units, same way as operating systems calculate it. Hard drive manufacturers use 10^12 bytes units based on which Required License Capacity is calculated. To learn more about storage units read article on our blog.
How to use this calculator?
Product: Select the Open-E product for which RAID array will be used.
RAID Type: Select either Hardware RAID or Software RAID. The Hardware RAID array is managed by any supported dedicated RAID controllers and is highly recommended to use for the RAID type. The Software RAID array is managed by the built-in software RAID manager.
Min. HDD Capacity: Capacity of the smallest drive in your array.
Number of HDDs: The number of drives you're planning to use in the array.
RAID Level: RAID configuration type determining collaboration of discs and fault tolerance.
Subunits: Two-level RAID configuration allow creating arrays that consist of already created RAID setups - "Subunits".
Unused HDDs: Number of HDDs that could not be utilized in selected RAID configuration
What do these results show?
Available Space: How much space will be available for your data in this configuration.
Required License Capacity: Required storage license space for building the RAID system for this configuration that will consists of the base storage and (optionally) additional storage extensions.
On our blog about RAID
RAID0 what it is, how it works?
We published an article about RAID 5: "How does RAID 5 work? The Shortest and Easiest explanation ever" - now is the time for the whole series.
What are RAID1, RAID1+0 and RAID0+1
This is the second article from our RAID series. We hope it shows - in the easiest possible way - what RAID is, the idea of it and how it works.
RAID2, RAID3, RAID4 what it is, how it works?
After RAID 0 and RAID 1 (with RAID 1+0 and RAID 0+1) it is time for RAID 2, 3 and 4. Here we present a small description of the mentioned levels.
RAID5? RAID6? Or other altErnativEE?
Here we are with the next part of our RAID series. This time the article will concern RAID 5, RAID 6 and two alternatives - RAID 5E and 5EE. Take a look...
