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
- 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,
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
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.
