[Completed] Scheduled Maintenance on Server: Atlas - March 25, 2009 at 1AM EST (GMT-5)

Recommended Posts

Just three days ago we announced that we had moved to an entirely new backup system using R1Soft CDP technology and today I am writing you to inform you of another beneficial upgrade to our systems and services. We are going to be installing Intel SLC Solid-State Hard Drives into our shared and reseller servers for MySQL. Disk input/output is a very important aspect of a web server and MySQL alone can cause hundreds if not thousands of disk input/output requests every second.


When MySQL is located on a mechanical drive such as the drives in use by nearly every provider there is additional overhead on every request that slows down each and every MySQL query. When a MySQL query is executed on a mechanical drive the drive spends time actually seeking the appropriate location on the disk drive and then more time reading and writing this data. The seek time is magnified significantly when the data you are wanting to read or manipulate is fragmented across the drive.


Solid-State drives have near instant seek times due to not having any mechanical moving parts whatsoever. This means when your scripts execute MySQL queries the results can be found lightning fast and independently of your html or php pages themselves. We believe this will greatly increase the speed at which dynamic scripts such as WordPress, Gallery, vBulletin, Invision Power Board, and other such dynamic scripts will run decreasing load times and reducing the strain placed on the web server with each and every request.


Another benefit to Solid-State drives over conventional mechanical drives is that they fail on the write instead of on the read. What this means is that when a Solid-State drive does begin to fail rather than your data being lost the error is caught on a write to the disk and the system simply writes the data to another location on the disk. This allows us to replace the drive when it begins to fail without you losing any of your important data. We of course have additional layers of redundancy built into our servers and systems such as our backup system in case of a catastrophic failure or a natural disaster to keep your data safe.


We have planned a 30-Minute window of downtime on March 25, 2009 at 1:00AM EST (GMT-5) to 1:30AM EST (GMT-5) however we anticipate the server will be offline for no longer than 10 minutes. If you have any questions, comments, or concerns about this system upgrade or the associated maintenance window please do not hesitate to contact the support department.


Thank you,
