Zone Redundant Storage (ZRS): Three copies of your data are stored across 2 to 3 facilities in one or two regions.3 read only asynchronously replicated (no deprecation in performance) copies are stored in the neighbouring region, offering facility and region fault tolerance, but with read-only access in that other region. Read-Access Geo-Redundant Storage (RA-GRS): synchronously replicated copies are stored in a single facility in your region of choice.This is the most expensive resiliency level. 3 asynchronously replicated (no deprecation in performance) copies are stored in the neighbouring region, offering facility and region fault tolerance. Geo-Redundant Storage (GRS): 3 synchronously replicated copies are stored in a single facility in your region of choice.Locally Redundant Storage (LRS): 3 synchronously replicated copies are stored in a single facility in your region of choice.There are 4 resiliency levels, summarized nicely here: You also set a resiliency level to provide you with some level of protection against physical system failure. You do not set a size you simply store what you need and pay for what you store with up to 500 TB per storage account, and up to 100 storage accounts per subscription (by default). This could be used publicly … only if you know the very long secret access keys. When you create a storage account you create a unique URL. A storage account is an address point in the Azure cloud with 2 secure access keys (a primary key and an alternate secondary key to enable resetting the primary without loss of service). You do not create LUNs in Azure storage in Azure comes in units called a storage account. Note that I will cover SSD-based Premium Storage in another post. Sorry – it’s actually all much simpler than that – that’s a good thing! They expect LUNs with predefined sizes, they expect to see RAID, and when you talk about duplicate copies, they expect to see each copy. There are a few things people expect when I present on storage in Azure. I’m going to try cut through a lot of stuff to help you select the right storage for IaaS solutions such as VMs, backup, and DR. You read through them, and are left none the wiser. You use the best pricing tool for Azure and land at a page that has a bewildering collection of 12 items. ![]() You’ve been asked to price up a solution with some virtual machines.
