Database and mail applications often push NAS systems to their limit, but can also be taxing on Direct Attached and SAN implementations. Not only is I/O valued over sheer sequential read/write, but uptime becomes crucial, as failure in mid-operation can cause corruption and unwritten requests mount with every second that a database is unavailable. Lighter throughput situations are well-served by 4 or 16-drive NAS appliances with RAID certified Serial ATA drives. More complex configurations are also available, with active-active RAID controllers for maximum I/O and seamless fail-over. DNF also has numerous direct-attached and SAN solutions for database and mail use. For all manner of operations, consider the highlighted products below and feel free to browse through our product menu. Contact us directly for additional information, or for a custom configuration!

NETWORK ATTACHED STORAGE
TaskMaster 16000 RAID	The FibreMaster 16000 RAID is the best option when exceptionally high availability and throughput are required. Dual active-active modular RAID controllers ensure transparent fail-over and help make the most out of the attached fibre channel storage systems, which utilize drives with rotational speeds of up to 15,000 RPM.
Enterprise 12320 RAID	The 12-bay Ultra320 SCSI-host 16320 is capable of over 3TB internal storage space and can be populated with SCSI-grade 10,000 RPM SATA drives for sustained throughput well above the single line speed of a fibre channel system. It is a good option if you're looking add medium amounts of directly attached storage capacity to existing mail servers.
