Netra 20 Server

The combination of UltraSPARCTM III microprocessor, SolarisTM 8 Operating Environment (Solaris OE) and ruggedized packaging in NetraTM 20 AC Server enable an architecture that is reliable, scales readily, and provides binary compatibility with existing applications. This reduces costs, provides higher system uptime and easier serviceability.

Netra 20 is a dual processor server that:

  • Provides easier administration and recovery through Lights Out Management (LOM) and System Configuration Card (SCC). LOM allows diagnosis to a component level even when Solaris OE is not running, and allows remote shutdown/restart. The SCC stores system settings and enables quick replacement of faulty systems.

  • Offers peace of mind: A highly reliable network even in sub-optimal environments.

  • Protects investments in existing infrastructure by maintaining consistency with Netra server values: consistent footprint, front-to-back cooling, rack optimization, status LEDs and remote management.

Netra 20 AC servers enable a rugged, reliable, and flexible solution for military/government, financial service providers, Internet data centers, and enterprise customers--any environment where compute density is key and space is at a premium.

The Netra 20 server is built to rack into virtually any network environment, with front-accessible components, front-and-back LEDs, removable system configuration card, and support for two- and four-post racks. All this capability is integrated into a compact 4U form factor with a 17.1- by 19.5-inch footprint designed specifically for space-conscious, rack-intensive environments. Each Netra 20 server has a System Configuration Card (SCC) that stores system's Host ID (used in software licensing), ethernet mac-address, and the default NVRAM settings. SCC facilitates easy transfer of the system configuration from system to system without reconfiguration. This facilitates quick replacement of faulty systems, minimizing downtime.

The Netra 20 Server has ruggedized packaging: operating temperature range of five degrees C to 40 degrees C, 20 percent to 80 percent relative humidity, noncondensing, subject to a maximum absolute humidity of 0.024 kg water/kg dry air.

Today's network infrastructure companies--including Telcos, application service providers, internet service providers, and co-location datacenters have a need for a tremendous number of server systems. Due to the limited space available in most datacenter environments, customers typically rack and stack their IT systems. A consequence of the close stacking, however, is a strict requirement for the systems in terms of manageability, serviceability, cooling and upgradeability. Netra products are designed specifically with these requirements in mind. Netra servers all have front-to-back cooling (so that one system doesn't simply heat up the next), front and back LED lights (so you can easily identify a single system in a rack from the front and the back of the stack), consistent footprint, minimal FRUs, a removable Host ID (all to aid in the replacement of a system from a rack), consistent cabling and a multitude of racking attachments (to aid in the racking process).

Automatic Server Restart (ASR) reduces operator intervention and provides maximum uptime. ASR provides system and component monitoring and initiates an automatic reboot without intervention in the event of a system failure. Failed components, such as a failed processor or DIMM, are excluded from a reboot. ASR also denies re-start if a significant failure has not been addressed.
