To further investigate the seeming disparity regarding the Linksys pair, I tested multiple sets of pairs. At three pair, I recorded Mbps; at five pair, Mbps; and at 10 and 20 pairs, Mbps.

As the Linksys pair is 3Com 3CR990-TX-97 10100 Secure NIC by high demand and simultaneous operations, the throughput actually increased considerably, bringing it within range of the top-performing Intel and 3Com entries Figure 3. The Linksys drivers ship on floppy disks, but included a great manual—a slim, detailed booklet.


For those of us who dislike manuals, Linksys provides a handy, one-page quick start card for each common OS. The Linksys card appears to 3Com 3CR990-TX-97 10100 Secure NIC a hybrid design somewhat similar to that of the SMC gigabit card: I used Category 6 cable for the testing. Although the card is compact, the first thing one notices is the large heat sink over the Broadcom ASIC.

The board itself became quite warm to the touch. As if to throw salt at top-tier and other manufacturers, the graphic on the box back claims throughput numbers showing NetGear besting both a similar but not the same Intel card and a D-Link entry. The power transistor is enveloped by a comparatively large heat sink screwed to the board.

The board appears to be dual-sided, at least for the traces, and there are two wires covered by epoxy running from the 3Com 3CR990-TX-97 10100 Secure NIC magnetics chip, indicating a later engineering change. 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 3Com 3CR990-TX-97 10100 Secure NIC 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, one 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 the 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. 3Com 3CR990-TX-97 10100 Secure NIC


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 3Com 3CR990-TX-97 10100 Secure NIC 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 loss, 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 3Com 3CR990-TX-97 10100 Secure NIC 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 card, but with better utilities.

Rumor has it that Adaptec will be coming 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 3Com 3CR990-TX-97 10100 Secure NIC workstations in use.

The firewall can also be configured to stop certain attacks originating from within the enterprise. In typical 3Com fashion, this can 3Com 3CR990-TX-97 10100 Secure NIC 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 a NIC, click 3Com 3CR990-TX-97 10100 Secure NIC 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.

3Com 3CR990-TX-97 10100 Secure NIC policy is associated with the NIC, which is simple to accomplish through the wizard. Keeping your network truly safe and secure - thats the thinking behind the 3Com 3CRTX Network Interface Card (NIC). This intelligent NIC helps to boost.
