NRT Online allows you to access the functionality of NetResults Tracker with just a browser and Internet access. Because there is no program to install, you can work when you want, where you want - at the office, at home, from remote offices or on the road.
- Browser – Internet Explorer 7.0+, Chrome 12.0+, Firefox 3.6+, Safari 4.0+.
- Internet Access – A high-speed connection (minimum 1 Mbps) is strongly recommended. NRT Online can be used without a high-speed Internet connection, but performance may be affected.
Availability and Reliability
NetResults Tracker Online has maintained an availability of 99.99% (outages totaling less than 53 minutes per year) for nine years in a row. Many of those years actually showed 100% availability according to our dozens of monitoring sites on the Internet; however, since our checking is at most once a minute from each location, we've been conservative in our numbers. The last time availability was lower than 99.99% was in 2005 (when it was 99.97%). And, even when there have been outages, no outage has ever resulted in customer data loss.
With enough luck a system with very little redundancy could perhaps achieve those numbers for 2 or 3 years. But to do it 9 years in a row, through many new application versions, operating system versions, database upgrades, hardware updates, and general technology changes requires more than just luck. It requires high quality software, highly redundant hardware, good fault-tolerant design, and proactive monitoring and servicing of the system by well-trained engineers.
To provide such high service reliability and data integrity we use:
- High-availability hardware. Our servers all have dual processors, redundant hot-swap power supplies, fully mirrored (RAID-1 or RAID-10) redundant hot-swap disk, redundant fail-over networking, redundant cooling, ECC memory, etc.
- High-availability power. Each server has two hot-swap redundant power supplies connected to two independent switched power distribution units, connected to two independent uninterruptable power supplies (for short term power outages), connected to multiple utility feeds and N+1 diesel generators (for long term power outages).
- High-availability cooling. N+2 industrial chilled water cooling, raised floors, cold-aisle containment, 32+ foot high ceilings.
- High-availability networking. The primary data center has fiber connections to three Tier 1 Internet service providers. The backup data center has fiber connections to two more Tier 1 Internet service providers. Redundant routing/switching pathways to each server. Automated 24x7 monitoring of the service from more than a dozen locations on the Internet with pager notification to multiple NetResults engineers.
- High-availability storage. In addition to each storage node in the SAN having the high-availability hardware mentioned above, the SAN itself is designed to survive failure of any single storage node without service disruption.
- High-availability software. Virtualization of servers so that even if a single physical server (with all redundant elements listed above) does fail, the virtual machines running on it can quickly be restarted on new hardware. In the case of planned hardware maintenance, live running virtual machines can be moved to new hardware without any service disruption.
- Multiple Tier IV data centers for disaster recovery.
- Multi-level security. Check in, biometric authentication (e.g. retina scan, palm reader), and pin code required for access. 24 x 7 CCTV monitoring inside and outside facilities.
