Integrity, confidentiality and availability are absolute requirements when dealing with databases which are a company’s repository for proprietary and sensitive information. NeoSpire takes database operations seriously and knows a company’s database server is likely the most critical asset within the hosted environment. Clients can expect premium-level service in regards to the day-to-day responsibilities of managing the database environment from our expert team of administrators.
Mission Critical Managed Hosting means never suffering unplanned downtime. NeoSpire manages some of the most serious business applications supported by MSSQL. Our experts can design and deploy the most appropriate high-availability solution based upon your technical and business requirements.
A high availability mirroring solution supports maximum database availability with automatic failover to the mirror database if the principal database fails. The high availability mode is best used when automatic failover is required for a single database. Since this solution involves cross-node transactions, the principal server must wait briefly for responses from the mirror server, and therefore, the performance of the principal server may be affected by the capability of the mirror server. Because a single database failure will cause an automatic failover, if you have multi-database applications, a different operating mode may be necessary.

Fully transactional safe data replication
Supports replication between physical locations
Witness server provides for automatic failover
Mirror database is not online and cannot be queried
Performance hit due to two-step, cross-node commit process
Must license SQL server on the principal and mirror servers
The High Protection operating mode also has full transactional safety, but has no witness server as part of the mirroring session. The principal database does not need to form a quorum to serve the database. In this mode only a manual failover is possible, because there is no witness to fill the tie-breaker role. An automatic failover is not possible, because if the principal server fails, the mirror server has no witness server with which to form a quorum.

Fully transactional safe data replication
Supports replication between physical locations
Full redundancy with only two nodes
Mirror database is not online and cannot be queried
Performance hit due to two-step, cross-node commit process
Must license SQL server on the principal and mirror servers
In the High Performance operating mode, transactional safety is off, and the transfer of log records is asynchronous. The principal server does not wait for an acknowledgement from the mirror that all transaction log records have been recorded on the mirror. The mirror does its best to keep up with the principal, but it is not guaranteed at any point in time that all the most recent transactions from the principal have been hardened in the mirror's transaction log. Since the safety is off, automatic failover is not possible because of potential data loss.

Very low replication overhead means transactions execute quickly
Supports replication between physical locations
Full redundancy with only two nodes
Mirror database is not online and cannot be queried
No guarantees that the mirror database is always 100% up-to-date
Must license SQL server on the principal and mirror servers
In Active/Passive clustering, SQL Server runs across two or more nodes, with only one node being active at any given moment. All nodes share a single storage system, typically a SAN. When the Active node has a failure one of the Passive nodes will assume control of the storage, take over the Active node’s IP address, and relaunch the SQL Server instance.

Zero transaction overhead
Very low cost since only one node must be licensed for SQL Server
Though the storage system can be made very redundant, it is still a single point-of-failure
Typically can only provide redundancy for hardware at a single site
