Configuring Active Directory and domain controllerAlthough local user account authentication is available, we configured Active Directory (AD) user account authentication in the lab to simplify user management. Hard disk formattingOne factor that can impact a disk's performance in a safety and security video system is the cluster size of the formatted hard disk. Enabling motion detectionIf motion detection is not working, you must enable a new rule for motion detection. Modifying the number of archive process threadsWhen using archive storage, such as NAS attached Isilon scale-out cluster, each recording server must be modified to use either three or four archive processes. By default, XProtect uses a single thread. Modifying the Archive DB write block size When using archive storage, such as NAS attached Isilon scale-out cluster, the Archive DB write block must be modified. Isilon OneFS for the Archive DBConfigure XProtect to use an Isilon cluster for the Archive DB. Multipathing and NIC failuresConfigure the Unity and SC block storage arrays with multiple paths to recorders using Microsoft MPIO. For redundancy, configure multiple NICs with the recorders and controllers. Recorders that are configured with multipathing reconnect to the volume across another available path after a NIC failure. iSCSI initiator queue depth on ESXi hosts Define the iSCSI initiator queue depth for each SAN attached ESXi host.
