| Thirty two CAD engineers shared a common Windows Server 2000 file server for storage of all CAD information. Server performance was too slow and storage capacity had been exhausted. The company sought advice in respect of replacement options and how best to integrate a new web-based tracking system. A new CAD engineer informed the company that his last employer had moved to a Linux server to gain better performance. |
The old server was replaced with a rack-mounted solution using white-box servers each decked out with 24x 1.5 TB SATA drives in 4 RAID5 arrays. The RAID5 arrays present to the operating system as separate LUNs. These LUNs are aggregated using software RAID. Samba provides the file and print services, and Apache2 provides the new web services. The local network was upgraded to gigabit Ethernet. Each server has an Intel Quad NIC card using bonded Ethernet. Performance of the new infrastructure is exceptional. |
| A medical equipment manufacturer HR department mandated centralized control of network access. The requirements specified the need for a single directory, file access tracking, network access control based on time-of-day. |
PrimaStasys provided an overview of different ways that site needs could be met. The site obtained solutions from software vendors but chose to implement OpenLDAP closely tied with Samba (previously already in use) and with RADIUS-based access control for all VPN facilities. |
