ATTN USERS OF PRODUCTS AND SERVICES
FROM RTH WASHINGTON DATA MANAGEMENT
OVER THE NEXT FEW WEEKS... THE NCF WILL BEGIN THE TRANSITION
TO NEW LINUX-BASED SATELLITE BROADCAST NETWORK UPLINK
SERVERS. THE NEW DEVICES WILL BRING GREATER RELIABILITY TO
AWIPS SBN UPLINK AND WILL SERVE AS THE FIRST OF SEVERAL STEPS
NEEDED TO IMPROVE PRODUCT DELIVERY TIME. THE TIME LINE FOR
THIS UPGRADE IS AS FOLLOWS
JUNE 11 NEW LINUX SERVERS POWERED UP AND CONNECTED AT ANCF...
BUT UPLINK STILL ACCOMPLISHED BY HP-UX SERVERS.
JUNE 12 4TH CHANNEL UPLINK /NON-GOES DCP/ MOVED TO NEW LINUX
SERVER.
JUNE 13 GOES-W CHANNEL MOVED TO NEW LINUX SERVER.
JUNE 17 REMAINING CHANNELS MOVED TO NEW LINUX SERVERS.
MOVING CHANNELS FROM THE HP-UX SERVERS TO THE NEW LINUX
SERVERS SHOULD CAUSE LITTLE TO NO DATA LOSS. INTERRUPTION
OF UPLINK SHOULD BE LESS THAN 5 MINUTES FOR EACH CHANNEL
TRANSITION. NCF WILL SEND AN ADMIN MESSAGE AS EACH CHANNEL
IS MOVED.
THERE WILL BE A TOTAL OF FOUR LINUX UPLINK SERVERS. EACH
SERVER WILL UPLINK ONE CHANNEL. SHOULD ONE SERVER
ENCOUNTER A PROBLEM... THE CHANNEL BEING UPLINKED FROM
THAT SERVER WILL BE MOVED TO ANOTHER. IF IT IS NOT POSSIBLE
TO SPARE TO ANOTHER LINUX UPLINK SERVER... UPLINK WILL BE
RETURNED TO AN HP-UX SERVER. TWO EXISTING HP-UX SERVERS
WILL REMAIN IN THE NCF UNTIL ABOUT JUNE 27.
NCF WILL BE MONITORING THIS UPGRADE CLOSELY AND WILL
INFORM SITES IF ANY PROBLEMS ARE ENCOUNTERED.
