== How does Hornbill measure space used ==
 
Hornbill only measures space used by your instances data, it does not measure disk space used by our software or any infrastructure components we deploy in order to deliver the Hornbill service.  The measurement is broken down into two separate domains known as "Disk Storage" and "Database Storage".  We separate these two for good reason. For "Database Storage" the underlying database we use (MariaDB) and its storage engine determine the space utilised for a given database (each customer instance has its own dedicated database).  For "Disk Storage" this is where we store files (see explanation of our [[Content Addressable File Store]] technology) below, each customer also has their own CAFS store.

== Storage Quota and Utilisation ==
 +
Every Hornbill instance comes with 30Gb of storage and additional storage can be purchased when needed. We audit storage utilisation daily and keep storage utilisation history on the following basis: -
 +
* Daily Database storage used for the last 90 days rolling
 +
* Daily Disk storage used for the last 90 days rolling
 +
 +
Your storage information can be seen in the Hornbill Administration tool under the [https://wiki.hornbill.com/index.php?title=Support_Passcode '''Your Subscriptions'''] section. Techniques available to manage storage consumption can be found [https://wiki.hornbill.com/index.php?title=Managing_Instance_Storage_Usage  '''here'''].

== Storage Size Definition ==
 +
There is sometimes confusion about abbreviated size values used in computing. For example, most uses of the team Gb mean Gigabyte, but there are two values this can mean, one is decimal, based on "1 byte x 1000 x 1000 x 1000" and the other is base 2, which is calculated as "1 byte x 1024 x 1024 x 1024). The modern interpretations of these size abbreviations are 1Gb = 1000000000 bytes and 1GiB = 1,262,485,504 bytes, and in general a Gb is what is normally used. The problem with base 2 calculations is the are non-linear so do not work properly as the computing technology has reached tera and peta byte scale, so the decimal scheme has been adopted generally, and this is true for the Hornbill platform.  To for the avoidance of any doubt, the following table sets out what we mean when stating storage sizes in Mb, Gb, Tb etc..
