Traditional high-availability solutions are costly, hard to implement, and difficult to manage.
On the other hand, we offer high availability options that provide continuous access to applications, data and content. They address every potential cause of downtime with their advanced design, functionality, and technology, and they do it with a smile, virtually speaking.
With External IT, your IT services and business-critical applications are delivered with the utmost reliability. This is all thanks to technologies covering both failover and load balancing, bolstered by hardware-independent backup and recovery.
Network hardware and software are integrated, giving you system level resiliency, network level resiliency, and embedded management.

Fault tolerant network infrastructure with synchronous mirroring
At External IT, we’ve designed our architecture in such a way as to deliver a particularly high level of fault tolerance, and to work especially well with synchronous mirroring for real-time I/O replication. For details, just click to our Architecture section.
Continuous data protection for servers with 24 hour rollback
Here you can have local backup with 24 hour rollback. Continuous Data Protection is a fabulous way to go for mission-critical database driven applications when you might want to visit a certain period of time, a particular transaction, or if there’s a corruption or user error.
Exchange High Availability plans
Here you have options:
| Exchange 2007 HA Options | |
|---|---|
| Local Continuous Rreplication (LCR) |
Maintains an exact replica of the Exchange database in either a single site or across multiple geo-dispursed data centers. |
| Single Copy Clusters (SCC) |
Clustered individual Exchange servers configured to failover from one to the other in the event of an outage. |
| Continuous Clustered Replication (CCR) |
This is the highest HA configuration available. No single points of failure across geo-dispursed data centers. |

Exchange 2010 HA
In Exchange 2010 deployments, implementation architecture is somewhat simplified: Database Availability Groups replace server clusters. However, the number of servers in your Exchange DAG and where those servers reside remains highly critical to achieving HA. In a multi-tenant Exchange deployment, multiple servers is the standard. In a dedicated Exchange environment, the client controls the number of Exchange Servers in the group. In addition, the server group can span one or more secondary geo-dispersed data centers for replication and disaster recovery.
SQL Server High Availability plans
Here you have two options: SQL Server High Safety Mirror or High Performance Mirror.
High Safety Synchronous Mirror
If you need to have every SQL application at two sites at all times, we can provide you with a high-safety, synchronous mirror service that will deliver identical data at either a local or remote site. This gives you the highest data protection mode with a performance hit for real-time data sync.
High Performance Mirror
This is similar to the high safety mirror service above, but configured with a primary and secondary server so the data is synchronous. This lets the primary perform at maximum speed, and data is queued. There is a potential data loss tradeoff for this highest performance mode in a worst-case scenario.
Distributed File System
At External IT, we use Microsoft controlled mechanisms for cloud-enabled network replication. This gives you the ability to make your file system look like a normal file structure when viewed by your staff, despite being spread out across the country, or even the globe.
