Storage at LuxSci

LuxSci uses very high performance, redundant storage for all shared and dedicated servers. LuxSci also makes extensive backup copies of your data and allows you request restores (see Backups). LuxSci's pricing for disk space reflects this premium infrastructure and the fact that cheap commodity drives and cheap cloud storage are not appropriate for high performance email and database services.

  • Business Class Services: These use RAID 10 SSD drives
    • The disk space that "comes" with a dedicated server is located on the Business Class Hypervisor.
    • Added blocks of disk space are pulled from a large shared Storage Area Network in the Rackspace public cloud. These can be encrypted upon request.
  • Enterprise Class Services: These use RAID 5 SAS drives in a large encrypted Storage Area Network (SAN) private to LuxSci. This SAN has multiple hot spares and uses an array of SSD caching drives to further speed access to stored data.

Disk Space in Shared Accounts

When comparing disk space limits in shared email hosting at LuxSci vs. other providers, please keep in mind:

Many providers give you a specific amount of space "per user".

  • Most users will use far less than their disk space limit; only a few power users will, in general, approach the limit
  • If a user reaches his/her limit, that limit is hard and that user's services will be interrupted!
  • There is generally no way to increase individual user limits! So, if the limit is 10 GB/user and you need 12 GB, you are completely out of luck.
  • These limits are not sharable among the account, i.e. 10 users with 10 GB/user does not give you 100 GB to distribute freely across all users.

At LuxSci, we do not impose per-user disk space limits. (Though as an administrator, you can)

  • Your disk space is "account wide" — i.e. hared by all users and services.
  • Each individual user can use as much disk space as needed and will not be cut off.
  • If your account-wide usage exceeds the purchased limit, you are merely charged for the extra space at regular prices — no services are interrupted.
  • You can easily add more space to your account as needed.
  • Unlike with other email providers, you buy the disk space you actually need and are not given some artificial per-user limit limit.

Disk Space in Dedicated Servers

When you have a dedicated server at LuxSci, your server has a certain amount of physical disk space available to it. This amount is a function of the size of the server (e.g. a Performance x2 has 30GB of space available) and can be expanded by purchasing additional disk blocks. LuxSci charges customers for the extra disk blocks to cover the cost of these blocks and the cost of the backups of that data.

A dedicated customer's disk space limit is set to the maximum size available on the server. Exceeding your allotted storage capacity can result in completely filling your servers disk and that can result in data loss and service down time.

We suggest that dedicated server customers purchase enough disk space so that they always have at least 20-30% free space and thus are never in danger of filling up their disks. LuxSci will be alerted if your disk is getting full and will contact you to suggest that the disk space be expanded or that unneeded data be deleted.
