April 2010 COPS/RMS Information Technology Service Availability Metrics Trey Felton Manager, IT Administration

2 Agenda and Commentary March 2010 Outages  A SAN switch which provides connectivity to the storage array failed after the switches were rebooted during maintenance, resulting in unplanned outage of Retail Transaction Processing on 3/8/2010 for 633 minutes. The failed components were replaced and disk data integrity scans (CHKDSK scan) were performed to restore the application. Since data integrity scanning contributed to 513 minutes of the outage, ERCOT is evaluating a solution to improve scanning efficiency.  A failure of a network switch resulted in TML outage on 3/1/2010 for 103 minutes. The incident was resolved by reconfiguring the network and rebooting the switch. ERCOT is working with the vendor to determine the root cause for switch failure to prevent recurrence.  On 3/25/2010, ERCOT took a maintenance outage after the SLA window to implement changes to MarkeTrak. Improvements in performance have been observed, and continue to be discussed at TDTWG.
