NetGear warranties its products for five years and includes a CD of driver support, along with a quick start poster.

Although I used shipping drivers for all the other cards, I did update the driver for this card from the NetGear Web site. With five pairs, the driver for this card consistently generated a bluescreen when running Chariot, a performance-evaluation tool.

With the second driver and one pair of connections, I generated an average throughput of Mbps and 45 percent utilization, and three pair returned Mbps and 46 percent utilization, both respectable. At five pair, and the high throughput script, 3Com 10/100 Secure NIC (3CR990B-97) of the endpoints failed in a bluescreen, indicating driver failure.

In attempts to track this down, I ran many other scripts, including the throughput script, which writes a much smaller file and all the Microsoft scripts I could find.

None resulted in a bluescreen, but when I increased the size of 3Com 10/100 Secure NIC (3CR990B-97) message contained in the Exchange script by a factor of three, Chariot would fail near the end with more than five pairs, indicating a TCP connection failure. Interestingly, the Chariot trace shows that the throughput periodically dips before recovering, then quitting.

When running very large file transfers under my simulated heavy loads, the drivers appear to have a TCP ack communication problem. With smaller transfers and moderate loads, there was no evidence of any problem; the throughput, under certain conditions, was much higher than I indicated above.

To be fair, the conditions I created may not exactly simulate real-world conditions, and a NetIQ white paper states that simulating large numbers of clients with few endpoints may lead to TCP ack failure. Nevertheless, the other entries tested showed little evidence of any problem. There are at least two outstanding entries here, however.

I tested this, and it worked as designed. In addition to failover for Ethernet link 3Com 10/100 Secure NIC (3CR990B-97), you may set watchdog timers, abnormal hardware interrupt, too many collisions or abnormal counters to trigger a failover.

The Quartet also supports both 3. All documentation comes on a CD, along with the drivers and some impressive management utilities. For four ports, there are only two annunciators each port, which is a disappointment. With the severe tests from Chariot, I generated in the middle to high s, depending on the test, well within the claimed range considering Ethernet inefficiencies. This card also supports Cisco Fast EtherChannel. The Quartet reminded me of my old favorite, a Mylex four-port, 10Mbps 3Com 10/100 Secure NIC (3CR990B-97), but with better utilities.

Rumor has it that Adaptec will be 3Com 10/100 Secure NIC (3CR990B-97) out with a gigabit version of this card. An additional box includes the firewall software.

The advantage of running the software on the NIC is that this frees up the processor, as well as provides an additional level of security at the actual servers and workstations in use. The firewall can also be configured to stop certain attacks originating from within the enterprise.

In typical 3Com fashion, this can all be managed from one console, as the management utilities are included. As an example, one of the 3Com manuals describes, in simple terms, how to create a no ping policy to prevent hackers from basic network discovery. In the policy server, under the management utility with the Firewall policy server, you simply select 3Com 10/100 Secure NIC (3CR990B-97) NIC, click on the Policy tab at the bottom of the screen, and click on the Create Policy icon.

A wizard guides you through selecting Deny ICMP and the proper direction, which blocks ping attempts. The policy is associated with the NIC, which is simple to accomplish through the wizard. For performance testing, I created some rule sets and measured modified performance with Chariot and QCheck.

Though some NICs claimed to be able to do gigabit Ethernet over Category 5 copper cabling, I wanted to eliminate cable crosstalk and, particularly, attenuation as a variable. With the exception of two crossover cables, which were Category 5e Belkin, www. A variety of ready-made scripts available on its Web site simulates different application mixes.

You have to install an endpoint that runs as a service on each of the pairs you test. I typically used between three and 50 pairs 3Com 10/100 Secure NIC (3CR990B-97) my testing and used two scripts: QCheck gives single numbers that reflect average throughput performance, as well as testing connectivity. I also used NetBench 7.
