AIDA-NG - What we avoid Shared Storage Devices
Server Cluster
single point of failure
Single Database Volume
shared RAID Storage Device

• Conventional Cluster Solutions typically use
  "shared" components, e.g. Application Software,
  Data Volumes, and Storage Devices.

AIDA-NG - What we avoid Database Replication
Standby Server
Operational Server
Database Operation
Database Replication
Corrupted Database Volume
Corrupted Database Volume
single point of failure

• A single database volume is in operation, which
  is replicated to the standby server
• Corrupted Volume is replicated ? Outage of the
  system ? Loss of service

The Goal Satisfied Customers

• Peter,
• See note from Kevin confirming that the
  transition onto AMS-UK is now complete. I like
  to add my thanks to everyone at Comsoft for your
  support in achieving this important milestone.
• The whole transition has gone very smoothly and
  the delay in transitioning the last Xx
  connections was due to a problem with the Xx
  system and NOT AMS-UK.
• Could you please forward this on to all
  interested parties at Comsoft.
• Regards,
• Malcolm.
• Gents,
• I believe all of you are aware that following an
  extremely successful transition of almost all of
  the users by the 1st week in September, we were
  stuck with problems with Xx connections.
  Following another set of testing, we have
  subsequently been able to transition them to
  AMS-UK today and I can thus declare that the user
  transition is complete. Although this is a week
  later than I had planned, in comparison to
  previous transitions of this magnitude, I cannot
  emphasise enough how well this has gone and would
  not have been achieved without a magnificent team
  effort and I take my hat off to them.
• Regards, Kevin
