MedAmerica Billing Services, Inc. (MBSI) provides high quality coding, billing, auditing, accounts receivable management and reporting services to hospitals and healthcare providers from their headquarters in Modesto, California. The challenges they faced were that shortly after they converted from ICD-9 diagnosis codes to ICD-10 codes that performance for the VDI desktops began to suffer noticeably. They chose Xangati to overcome these challenges, which provided the Xangati Virtual Appliance (XVA). It pinpointed the problem that all of the hosts were using a single controller on the Tegile storage system, while the second controller sat in a passive stand-by mode. Rebalancing the storage controller usage solved the problem, which was caused by the inefficient layout of the database for ICD-10 diagnostic codes.
