BT Diamond IP Sapphire Ev10 IPAM appliance provides centralized IP address management (IPAM) capabilities for mid-range applications. The Sapphire Ev10 runs BT's IPControl software to enable management of your IPv4 and IPv6 address space and to configure your premises or cloud-based Sapphire, ISC or Microsoft DHCP and DNS services. Your Sapphire Ev10 may also be instantiated to serve as a redundant peer for cloud-based IPAM database backups of your primary IPControl deployment. Sapphire appliances are built from the ground up for security and robustness. Our appliances offer numerous security features including a hardened operating system (OS), network interface access control lists (ACLs), minimal open ports, uninterruptible boot process and jailed file system to name a few.
