Gigabyte LAN Networking = laju sangat ke?

kroeGand · Post time 10-4-2008 03:27 AM

dari pemahaman dan pemerhatian aku Gbit ethernet kat tempat aku cuma digandingkan dgn server yg power2 je. ni kerana server pakai SCSI plus HD nye write speed pun tinggi. yg kat pc cokia tak connect pasal
1) da mencukupi pakai Fast Ethernet adapter (x de keperluan utk upgrade)
2) write speed kat hard disk x cukup power pasal hd lama. so anta laju mana pun tak de guna nya. cukup la dgn apa yg ada

file transfer mmg laju le klu buat antara server tuh

klu ko nak lagi laju aku cadangkan pakai 10Gigabit ethernet port tapi make sure HD tu write speed tinggi mcm SATA II

Nak pakai Gigabit Ethernet(1000) kene pakai CAT6 cabel... kalau CAT5 tu untuk Fast Ethernet(100mb) je..

bit ye... bukan byte...

CAT6 tu still guna RJ45 kan? (soket LAN pun RJ45).

ada guide tak nak crimp dia cemana?

bzzts · Post time 10-4-2008 09:39 AM

betul le, suma hdd baru, 320GB SATA2. buffer memasing 16MB.

still RJ-45.... crimp cable die same cam cat 5..

A ngan A... B ngan B..... kalau nak cross, A ngan B je.....

Category 6 cable, commonly referred to as Cat 6, is a cable standard for Gigabit Ethernet and other network protocols that is backward compatible with the Category 5/5e and Category 3 cable standards. Cat-6 features more stringent specifications for crosstalk and system noise. The cable standard provides performance of up to 250 MHz and is suitable for 10BASE-T / 100BASE-TX and 1000BASE-T (Gigabit Ethernet). It is expected to suit the 10GBASE-T (10Gigabit Ethernet) standard, although with limitations on length if unshielded Cat 6 cable is used.

The cable contains four twisted copper wire pairs, just like earlier copper cable standards. Although Cat-6 is sometimes made with 23 gauge wire, this is not a requirement; the ANSI/TIA-568-B.2-1 specification states the cable may be made with 22 to 24 AWG gauge wire, so long as the cable meets the specified testing standards. When used as a patch cable, Cat-6 is normally terminated in 8P8C modular connectors, often incorrectly referred to as "RJ-45" electrical connectors. Cat-6 connectors are made to higher standards that help reduce noise caused by crosstalk and system noise. Attenuation, NEXT (Near End Crosstalk), and PSNEXT (Power Sum NEXT) are all significantly lower when compared to Cat-5/5e.

dari wiki yg ko bagi tu :

Cat 1: Currently unrecognized by TIA/EIA. Previously used for POTS telephone communications, ISDN and doorbell wiring.
Cat 2: Currently unrecognized by TIA/EIA. Previously was frequently used on 4 Mbit/s token ring networks.
Cat 3: Currently defined in TIA/EIA-568-B, used for data networks using frequencies up to 16 MHz. Historically popular for 10 Mbit/s Ethernet networks.
Cat 4: Currently unrecognized by TIA/EIA. Provided performance of up to 20 MHz, and was frequently used on 16 Mbit/s token ring networks.
Cat 5: Currently unrecognized by TIA/EIA. Provided performance of up to 100 MHz, and was frequently used on 100 Mbit/s ethernet networks. May be unsuitable for 1000BASE-T gigabit ethernet.
Cat 5e: Currently defined in TIA/EIA-568-B. Provides performance of up to 100 MHz, and is frequently used for both 100 Mbit/s and gigabit ethernet networks.
Cat 6: Currently defined in TIA/EIA-568-B. It provides performance of up to 250 MHz, more than double category 5 and 5e.
Cat 6a: Future specification for 10 Gbit/s applications.
Cat 7: An informal name applied to ISO/IEC 11801 Class F cabling. This standard specifies four individually-shielded pairs (STP) inside an overall shield. Designed for transmission at frequencies up to 600 MHz.

bila pulak 10Gbit ni nak kuar aaa :re:

x tau la bro..... para2 engineer nak tumpukan dkt WLAN je kot skg ni.... skg dah sampai N untuk rumah 248mb/s...

bzzts · Post time 10-4-2008 04:05 PM

tu la, aku baru je usha wifi 11n, kononnya max 300mbps...

kroeGand · Post time 11-4-2008 04:29 PM

isk dah kuar dah cuma tak fully commercialized lagi utk retail. klu x silap mcm kat Telekom dah ada dah tapi pakai utk backbone network je lah

tapi for sure akan ada beza lah kalau kau pakai Gbit Ethernet ni. just make sure network equipment semua Gbit Ethernet compliance je. HD tu pun dah SATA sure ok nye tuh. silap2 belum sempat tekan enter file dah kena transfer pasal power gile Gbit Ethernet nih

just my 2 yen

bzzts · Post time 12-4-2008 01:46 AM

kiranya wiki ni kena update la ye? 10gigabit dah kluar ye?

thanks for de info.

hardware aku suma dh tip-top. cuma nk "bida'ah" kan usage aje...

kroeGand · Post time 12-4-2008 03:26 AM

yup dah kuar. klu ko nak beli router or switch dia bole try tanya Juniper, Huawei, Alcatel and some other telecommunication equipment provider. tapi harga dia

ni some stories about TM nye new network
http://www.alcatel-lucent.com/wp ... News_Article_000348

klu sesapa perasan TM ada iklan pasal new product nama dia metro e. ni le sebahagian drpd TM punye NGN (Next Generation Network) yg diorang nak pakai pure IP base network dan nak tutup legacy/traditional TDM base network tuh. pendek kata lepas ni ATM/Frame relay tu semua bole bungkus le.

dan klu jadi HSBB nanti aku teringin nak merasa Gbit ethernet sampai ke umah pakai FTTH mcm kat Jepang tuh. setakat nak d/load anime tu sure kejap gilos

cuma subscription fee tu je la yg confirm mahal giler

owh .. ok .. bleh ek camtu ..

bzzts · Post time 12-4-2008 06:24 AM

buleh aje. dulu aku campur 8port HUB + 5port switch sbb port tak cukup.

HUB 10mbps je, SWITCH 100mbps.
takkan GLAN takleh gabung ngan SWITCH 100mbps kot?

wifi 11a/b/g/n pun buleh kawtim...

ctredzuan · Post time 12-4-2008 06:30 AM

nak tanya, apakah gigalan ittew... adik bzsstt sila terangkan, ahkak kureng jelas

networking guna kabel (LAN).

dulu cuma ada network HUB yg kelajuan cuma 10mbps.
pastu network SWITCH pulak kluar dgn speed 100mbps.
skrg dah ada yg baru, Gigabit LAN, speed 1,000mbps (1GB/s)

sekian. mekaseh.

aku ada soklan tambahan .. er .. tapi tunggu aku lukis rajah dulu la .. hhehe .. malam sket kot ..

pada pandangan aku memang laju la..pasalnye kat U aku pakai Gigabit LAN

transfer software dari server ke pc mengambil masa yang agak singkat berbanding transfer dari pc tersebut ke dlm external hdd

bzzts · Post time 12-4-2008 05:10 PM

external hdd guna USB je. mana nak lawan Gigabit speed?

How fast is USB 2.0?
USB 2.0 has a raw data rate at 480Mbps, and it is rated 40 times faster than its predecessor interface, USB 1.1, which tops at 12Mbps. Originally, USB 2.0 was intended to go only as fast as 240Mbps, but in October 1999, USB 2.0 Promoter Group pumped up the speed to 480Mbps.

As far as we know, effective rate reaches at 40MBps or 320Mbps for bulk transfer on a USB 2.0 hard drive with no one else is sharing the bus. Flash Drives seem to be catching up too with the some hitting 30MB/s milestone. For all we know, USB interface could become become the bottleneck for flash drives as early as 2008.
