Going Green with CHARON-VAX
WorkflowOne Saves Both Energy and Money
WorkflowOne in Dayton, Ohio needed to add more servers to
data center. But their data center UPS was at 95% of capacity.
The Old Hardware
After research, they discovered
that their old VAX systems were drawing most of the power. They
had a 3-CPU VAX 7630 and a 5-CPU VAX 7850 in a clustered
configuration. And about 800 GB of data, in ancient disk drives.
Via email and phone, Quayle Consulting supported Mark Gillespie and
John Moore of WorkflowOne during a proof-of-concept that showed that
CHARON-VAX could replace their entire VAX cluster.
CHARON-VAX is a VAX emulator that runs on a Windows system. The
operating system (VMS), application and data were moved to the
emulated system. Since the system emulates a VAX completely,
right down to the hardware, no changes were required to the application
or data. The part that took longest was copying the data itself.
Stanley Quayle of Quayle Consulting then came on-site to support the
production cutover to the CHARON-VAX system. A few minor issues
were encountered and overcome. The emulated VAX was on-line!
The New Hardware
WorkflowOne selected a HP Proliant server and external disk array,
pictured here. The server is running Microsoft's Windows Server
Some numbers captured by the client:
|Annual Maintenance costs
|48 square feet
|4 rack units (9 inches)
The performance of the CHARON-VAX system was also faster:
|Full backup time
|12 hours 33 minutes
|1 hour 41 minutes
|End of month sales processing
|8 hours 33 minutes
|1 hour 8 minutes
Mark Gillespie's email to senior management says it all:
|Here’s some good news about the
VAX migration. We figured our annual savings on the maintenance
contract alone would be in the 100K range. This does not include the
savings from electrical power or lower A/C use.
I just redid the contract with Hewlett Packard, keeping the two
remaining systems for Development and OMNI, as well as the Right to Use
license for the new emulated VAX.
Annual cost before taking out migrated VAX equipment: $120,178.34
Annual cost with the equipment we have now: $14,787.84
Annual cost avoided: $105,380.50
This is about a 1-year payback
after considering the CHARON-VAX licenses, new hardware, and
WorkflowOne has since purchased a second CHARON-VAX key. In the
event of a disaster, they can recover almost anywhere, not just where a
VAX might be available.
