我手頭上有2948G-L2 , 這台還中古貨蠻便宜的 ... 只是好吵...  況且這台L2 switch也不算是小switch , 2U 的高度, 48 port 10/100 interface 可以用在中型公司的core switch 了 !! 只不過這樣的中古機器也沒有1G的速率... 再說,Cisco也從沒出過小switch(體積小的那種),就死心吧!! 3Com可以試著找找看... 嫌貴,就只好轉向買國產品了(我寧願把買這種機器的錢拿來買2948G + GBIC(fiber or RJ -type都好) Cisco早期的產品,我有信心超級耐用....(當然還是要好好保養並清理灰塵及風扇)

當流量一大，性能差別就出來，而事實上Intel的確是把PRO/1000 PT Desktop的效能和功能封印起來 |

HP ProCurve 1800 或 Dell PowerConnect 27系列也不錯，在家中使用足夠了 |

昨天也用iperf測了一下PCI和PCI-E的差別
iperf版本1.7.0(新的找不到windows下的) 一端是桌機內建Marvell 88E8056，OS是WinXP SP3 另一端是Core Duo MODT電腦，OS跑FreeBSD 6 內建Intel 82573L Intel PRO/1000 PL Network Adaptor (應該是走PCI-E的) 另外插一張Intel Pro 1000/GT在PCI Switch是ASUS GigaX 1108M (之前很便宜的那台GbE switch) 網路線是雜牌Cat 6 server端參數 iperf -s -w 65536 Marvell 88E8056 -> Intel Pro 1000/GT (PCI) iperf -c 192.168.1.160 -w 65536 -P 10 -t 180 ------------------------------------------------------------ Client connecting to 192.168.1.160, TCP port 5001 TCP window size: 64.0 KByte ------------------------------------------------------------ [1864] local 192.168.1.173 port 2475 connected with 192.168.1.160 port 5001 [1832] local 192.168.1.173 port 2477 connected with 192.168.1.160 port 5001 [1800] local 192.168.1.173 port 2479 connected with 192.168.1.160 port 5001 [1848] local 192.168.1.173 port 2476 connected with 192.168.1.160 port 5001 [1816] local 192.168.1.173 port 2478 connected with 192.168.1.160 port 5001 [1912] local 192.168.1.173 port 2472 connected with 192.168.1.160 port 5001 [1880] local 192.168.1.173 port 2474 connected with 192.168.1.160 port 5001 [1784] local 192.168.1.173 port 2480 connected with 192.168.1.160 port 5001 [1768] local 192.168.1.173 port 2481 connected with 192.168.1.160 port 5001 [1896] local 192.168.1.173 port 2473 connected with 192.168.1.160 port 5001 [ ID] Interval Transfer Bandwidth [1768] 0.0-180.0 sec 1.77 GBytes 84.5 Mbits/sec [1800] 0.0-180.0 sec 1.81 GBytes 86.5 Mbits/sec [1848] 0.0-180.0 sec 1.72 GBytes 81.9 Mbits/sec [1784] 0.0-180.0 sec 1.64 GBytes 78.3 Mbits/sec [1832] 0.0-180.2 sec 1.77 GBytes 84.5 Mbits/sec [1880] 0.0-180.2 sec 1.66 GBytes 79.2 Mbits/sec [1912] 0.0-180.2 sec 1.65 GBytes 78.8 Mbits/sec [1816] 0.0-180.2 sec 1.68 GBytes 80.2 Mbits/sec [1896] 0.0-180.2 sec 1.74 GBytes 83.1 Mbits/sec [1864] 0.0-180.4 sec 1.81 GBytes 86.1 Mbits/sec [SUM] 0.0-180.4 sec 17.3 GBytes 822 Mbits/sec Marvell 88E8056 -> Intel 82573L iperf -c 192.168.1.170 -w 65536 -P 10 -t 180 ------------------------------------------------------------ Client connecting to 192.168.1.170, TCP port 5001 TCP window size: 64.0 KByte ------------------------------------------------------------ [1768] local 192.168.1.173 port 2503 connected with 192.168.1.170 port 5001 [1880] local 192.168.1.173 port 2496 connected with 192.168.1.170 port 5001 [1896] local 192.168.1.173 port 2495 connected with 192.168.1.170 port 5001 [1912] local 192.168.1.173 port 2494 connected with 192.168.1.170 port 5001 [1816] local 192.168.1.173 port 2500 connected with 192.168.1.170 port 5001 [1848] local 192.168.1.173 port 2498 connected with 192.168.1.170 port 5001 [1784] local 192.168.1.173 port 2502 connected with 192.168.1.170 port 5001 [1800] local 192.168.1.173 port 2501 connected with 192.168.1.170 port 5001 [1832] local 192.168.1.173 port 2499 connected with 192.168.1.170 port 5001 [1864] local 192.168.1.173 port 2497 connected with 192.168.1.170 port 5001 [ ID] Interval Transfer Bandwidth [1784] 0.0-180.0 sec 1.90 GBytes 90.5 Mbits/sec [1800] 0.0-180.3 sec 2.02 GBytes 96.1 Mbits/sec [1848] 0.0-180.3 sec 1.89 GBytes 90.0 Mbits/sec [1832] 0.0-180.3 sec 2.12 GBytes 101 Mbits/sec [1896] 0.0-180.3 sec 2.10 GBytes 99.9 Mbits/sec [1880] 0.0-180.3 sec 1.93 GBytes 91.7 Mbits/sec [1912] 0.0-180.3 sec 1.95 GBytes 92.8 Mbits/sec [1864] 0.0-180.3 sec 2.06 GBytes 98.2 Mbits/sec [1768] 0.0-180.3 sec 2.04 GBytes 97.1 Mbits/sec [1816] 0.0-180.3 sec 1.84 GBytes 87.7 Mbits/sec [SUM] 0.0-180.3 sec 19.8 GBytes 945 Mbits/sec 不過實際檔案傳輸都差不了太多，好像是都卡在硬碟IO， 所以最多衝到5~60MB/sec而已。 |
