DCF Technologies provides a plug-and-play software called SafePeak that reduces database latency and bottlenecks to micro second response times. SafePeak caches query results and database metadata in high-speed RAM to avoid disk access for repetitive queries. It ensures high availability through failover between active and passive servers and automatic redirection of queries in the event of software or hardware failures. Sample results for a large financial portal showed a 378% increase in throughput at peak times and a 371% improvement in response times for read-only queries with SafePeak.

6. Flow Process – Query In Cache
(C1) Query is found to exist;
result set is retrieved from
the Cache Manager
(C2) Result is returned to the
querying application
6

7. Flow Process – Query Not In Cache & Not Update
(Q1) Query is processed on
target database
(Q2) Result set is returned
(Q3) If repetitive query,
result set is saved in RAM
memory of the Cache
Manager to be accessed
upon the next instance of
the identical query
7

8. Write Request (update, insert, delete)
(U1) Request is parsed and all
results stored in Cache that
have any connection to the
affected database tables are
evicted
(U2) Request is sent to target
SQL Server database and
executed
(U3) Result set is sent back to
the querying application

10. Ensuring High Availability
(A1) Query is routed to Active SafePeak
Query Active server, using MS NLB (VIP) technology
(A1) (A4)
Network Proxy (SafePeak Enterprise version), and then
thru Network-Proxy SW to SafePeak (A2).
(A2) (A3, A4) In the rare event of software
failure, processing is automatically
(A2) redirected to 2nd SafePeak (A3 - optional)
SafePeak or directly to the database (A4).
Cluster
(P1) (A3) optional (P1) If a HW error occurs due to a
Virtual IP malfunctioning server, processing is
Passive automatically shifted into passive
(P3) SafePeak, ensuring that the loss of the
Network Proxy server will not impact continuous
processing.
(P2) (P2) Query is then routed to 2nd SafePeak.
(P2) (P3) If error occurs, processing is
SafePeak redirected to the SQL Server database
