Funding for the recent improvements was set aside in HASCS's $4.8 million budget and no extra money was allocated for the upgrade, according to Steen.
HASCS planned an 18-hour system shutdown last Saturday and Sunday to copy the directories from the existing storage space to the new disk array.
But the system remained shut down seven hours longer than scheduled.
"The copy didn't go quite as well as we expected it to," Osterberg said. "We were very upset with ourselves that we didn't accurately forecast it."
HASCS also performed an unscheduled system shutdown early Friday morning to resolve conflicts between the new disk array and e-mail software, Osterberg said.
Osterberg said he believes the shutdowns did not affect many users.
"We were fortunate that it was spring break and the usage was low," he said
