Отчёт о Ixia тестировании производительности FS коммутаторов серии S3900

Опубликовано 27 сентябрь 2019 г. От FS.COM

  

Компания FS сотрудничает с Ixia, отраслевым центром тестирования коммутаторов, чтобы провести тестирование производительности на основе RFC 2544 для FS коммутаторов серии S3900. Серия S3900 состоит из трех моделей: S3900-24T4S, S3900-24F4S, S3900-48T4S, которые представляют собой игабитные управляемые стекируемые коммутаторы, оснащенные микросхемами Broadcom с поддержкой 10G SFP+ uplink, предназначенные для SMB, кампусных сетей и корпоративных сетей.

Ключевые результаты теста Ixia FS коммутаторов серии 3900

Результаты тестирования Ixia на основе RFC2544 FS коммутаторов серии S3900 в основном фокусируется на пропускной способности, частоте потери кадров и латентность, которые являются важными функциями аппаратных средств при оценке производительности сетевого коммутатора. Основные выводы в результате тестирования следующие:

Пропускная способность：Все результаты по пропускной способности соответсвуют стандарту для гигбитных портов и портов 10G.
Коэффициент потери кадров: Частота потери кадров всех трех гигабитных коммутаторов составляет 0%, что означает отсутствие потери кадров вообще.
Латентность: Латентность колеблется от 0-45k нс на портах 1G и 0-6k нс на портах 10G, превосходит требуемые 50-125k нс для гигабитных портов и 5-50k нс для портов 10G на всем рынке.

Испытательный стенд

Тест Ixia с шасси Ixia XGS12-SDL начинается с отправки фреймов с заданной скоростью, и фреймы отправляются и принимаются на устройстве Ixia, с помощью которого записывается реальная пропускная способность, частота потери кадров и латентность коммутатора S3900 .

Анализ отчетов о Ixia производительности FS коммутаторов серии S3900

Отчеты о тестировании Ixia показывают реальную производительность пропускной способности, частоты кадров и латентности коммутаторов у коммутаторов серии FS 3900 (S3900-24T4S, S3900-24F4S и S3900-48T4S) с визуализированными данными.

Пропускная способность

Пропускная способность определяется как максимальная скорость пересылки, которую сетевой коммутатор может достичь без потери одного пакета. Мера скорости линии пересылки пакетов основана на количестве 64-байтовых пакетов (минимальных пакетов), отправленных за единицу времени. Стандартная скорость пересылки пакетов составляет 1,488 Мбит/с для порта Gigabit Ethernet и 14,88 Мбит/с для порта 10G при пересылке 64-байтового пакета. Вот теоретическая скорость пересылки/пропускной способности трех коммутаторов S3900.

Предмет	S3900-24T4S	S3900-24F4S	S3900-48T4S
Количество 1G порта	24	24	48
Количество 10G порта	4	4	4
Теоретическая пропускная способность	95 Мбит/с	95 Мбит/с	130 Мбит/с

Тестируются оба порта 1G и 10G трёх коммутаторов S3900. Реальная пропускная способность трех гигабитных коммутаторов достигает теоретического значения. В качестве примера возьмем четыре порта 10G S3900-24T4S.

S3900-24T4S 10G Port Performance.png

Реальная скорость пересылки/пропускной способности четырех портов 10G составляет 59523809.4 FPS (на основе 64 байтов). Таким образом, реальная средняя скорость пересылки для каждого порта 10G составляет 14880952.35 FPS (14.880952.35 Мбит/с), что почти совпадает с теоретической скоростью пересылки 14,88 Мбит/с. Точно так же реальная средняя скорость пересылки для каждого порта 1G составляет 1.488 Мбит/с, что соответствует теоретической скорости. Реальная пропускная способность FS коммутаторов серии 3900, протестированных Ixia:

Ixia Тест	S3900-24T4S	S3900-24F4S	S3900-48T4S
Реальная пропускная способность порта 1G	35.71 Мбит/с	35.71 Мбит/с	71.42 Мбит/с
Реальная пропускная способность порта 10G	59.52 Мбит/с	59.52 Мбит/с	59.52 Мбит/с
Реальная общая пропускная способность	95.23 Мбит/с	95.23 Мбит/с	130.94 Мбит/с
Теоретическая пропускная способность	95 Мбит/с	95 Мбит/с	130 Мбит/с

Коэффициент потери кадров

Определяемый как процент кадров, которые должны были быть переданы сетью, но не были, коэффициент потери кадров тесно связан с общей производительностью службы устройства. Ни один из трех гигабитных стековых коммутаторов FS S3900 не теряет пакет или кадр при тестировании Ixia. Коэффициент потери кадров у них составляет 0%, что в точности соответствует теоретической ситуации.

Латентность

Латентность переадресации коммутатора - это время, которое требуется коммутатору для перемещения пакета со своего входящего порта на свой исходящий порт. По сути, тест латентности измеряет, насколько быстро коммутатор может переслать пакет. Обычно латентность коммутатора для коммутатора Gigabit Ethernet составляет от 50 до 125 мкс (50–125 нс), а для коммутатора 10 Гбит/с - от 5 до 50 мкс (5–50 кс). Чем короче латентности, тем выше производительность коммутатора.

Для гигабитных коммутаторов серии S3900 латентности коммутатора в гигабитных портах даже колеблется в диапазоне от 0 до 45 тыс. нс, что меньше обычных 50-125 тыс. нс. Это указывает на то, что этот коммутатор имеет намного лучшую производительность в задержке, чем «стандартные» ситуации.

Заключение

FS управляемые стекируемые гигабитные коммутаторы серии S3900 - это высококачественные сетевые коммутаторы с высокой пропускной способностью, без потери кадров и низкой латентностью. Максимальная пропускная способность - до 130 Мбит/с при скорости линии 100%, что соответствует теоретическому числу. Частота потери кадров достигает наилучшего значения 0%, а латентность колеблется от 0-45тыс нс для портов 1G и 0-6тыс нс для портов 10G, что намного ниже, чем в среднем по всему рынку, что указывает на отличную производительность с низкой латентностью.

A:
I think the answer is yes as this is what I do От FS на 5 май 2021 г.
Q:
it stated that prot 27 and port 28 are for stacking, if i connect a server or storage on that port 27 and port 28, and i connect a machine on the another port on the same switch, can i ping the machine connected on port 27 and 28? or those two ports are only for stacking От Alec George на 6 апрель 2021 г.

A:
Yes. Ports 27 and 28 can be used as regular ports. They don't have to be used for stacking. От FS на 7 апрель 2021 г.
Q:
hi does fs3900 SFP+ port support 2.5G speed. I'd like to connect usb to ethernet port 2.5G device От EOS.Srl на 18 март 2021 г.

A:
Hello, 2.5G is not supported. От FS на 18 март 2021 г.
Q:
Hi, is there a way to set a default gateway for the Management Interface - or is the accesss only possible from the same network Segment? От Sebastian.Schubert на 19 октябрь 2020 г.

A:
Hello, the s3900 management port is not isolated from the service interface, so you only need to write a default route. For example: IP route 0.0.0.0 0.0.0.0 10.32.133.254 От FS на 20 октябрь 2020 г.
Q:
My switches are running the most recent release of the software available, but the ssh server implementation is so ancient that it cannot interoperate with even a four-year-old Ubuntu 16.04 client. When can this be fixed? От Garrett.Wollman на 26 август 2020 г.

A:
Hello, our switch supports ssh2.0, please describe in detail "the implementation of sh server is so old". Asymmetric encryption support: RSA1, DSA2 Symmetric encryption support: AES-128, AES-192, AES-256, 3DES, des_cbc, Blowfish HASH support: MD5, SHA1 От FS на 27 август 2020 г.
Q:
After the S3900 switches are stacked, the device has lost the stacking port. What is the reason? От henson на 19 июнь 2020 г.

A:
After the S3900 switch is successfully stacked and you check the port status through the commands, the two stacking ports of the device will disappear which is a normal situation. It is mainly to prevent misoperation. Please don't worry. От FS на 19 июнь 2020 г.
Q:
Why is the calendar set time of the switch restored after restarting? От Emoef на 18 июнь 2020 г.

A:
The time of calendar set is not saved in the configuration file so it will not continue counting after the device is turned off. It is recommended to use the ntp service to synchronize the system time, so that after the switch restarts, you only need to set the next restart time, and don‘t need to set the system time again. От FS на 18 июнь 2020 г.
Q:
When multiple S3900 switches are stacked, one of them will go down. Will it affect the normal operation of other switches? От Soucie на 16 июнь 2020 г.

A:
If the master is down, it will re-elect, the election process is the same as the first stack. If it is a slave downtime, there will be no impact. От FS на 16 июнь 2020 г.
Q:
Can the stacking and LACP functions of the S3900 be used together? От Helfer на 15 июнь 2020 г.

A:
Yes, after the S3900 switches are stacked, they are logically one device and can implement LACP with other devices. От FS на 15 июнь 2020 г.
Q:
Hello, why do I fail to upload firmware to the S3900 switch when upgrading the switch? От Dennis Haislip на 12 июнь 2020 г.

A:
The S3900 series switches only support a maximum of 2 firmwares. Please use the command dir to check whether there are currently two firmwares. If so, you need to delete one and add the new one. If there is only one, please check whether the firmware is damaged. It is recommended to download and install again. От FS на 12 июнь 2020 г.
Q:
When configuring QinQ, how many QinQ can be configured for each port? От Jimmina на 10 июнь 2020 г.

A:
The S3900 series are the access layer switches, which have certain restrictions on the hardware, so the maximum entry for QinQ is 24 per port. От FS на 10 июнь 2020 г.
Q:
I'm currently evaluating your products for our own infrastructure. I think that your S3900-24T4S could be a good solution for our needs. I need 8 switch to popolate our racks and providing access connectivity to our servers. The main issue is that I also need 2 core switch for connecting the access layer each other and uplink to the network perimeter. I've not found in your catalog a switch model that couldd be used for this scope.We have in plan to upgrade the network with more advanced features in the next future so, for now, I'm investigating the market for an affordable solution. I'm evaluating ubiquity products becaue this vendor has a 12 SFP+ ports available in its catalogue. От Popovich на 9 июнь 2020 г.

A:
Hello, i see you need a solution for your network; our tech and salers can help you design your whole network solution with best quality and price. And we recommend the S3900-24T4S for you to connect to the server. The function of the core switch is more abundant than that of the access layer switch. So as for the core switch, we recommend S5800-8TF12S for the core switch. От FS на 9 июнь 2020 г.
Q:
Does the QinQ function of S3900 series switches support no vlan tags or add double vlan tags? От Jamange на 9 июнь 2020 г.

A:
The S3900 series switches don't support no vlan tags or add double vlan tags yet, but the S58 series switches support these. От FS на 9 июнь 2020 г.
Q:
The S3900 series switch is configured with the sflow function, and then after saving the configuration and restarting, the sflow function disappears. What is the reason? От Aneili на 8 июнь 2020 г.

A:
After the switch is configured with sflow function, the configuration file will not display the sflow configuration. When you check the Sflow configuration command, it will show sFlow. От FS на 8 июнь 2020 г.
Q:

The S3900-24T4S switch could not support the feature that LACP works across the stack, the # 85069 S5850-24T16S switch, which supports MLAG and could meet your need well. От FS на 10 февраль 2020 г.
Q:
Bonjour, j’avais une question sur la partie SFP+. Le switch S3900-24T4S est équipé de 4 ports 10G. Peuvent-ils tous être utilisés pour connecter des serveurs/pc? Dans l'une des question déjà posé, il est indiqué que ses ports peuvent les accueillir, mais dans la documentation, il semble que les port 27 et 28 sont réservé au stacking. Merci par avance. От Mathieu.Canevet на 4 декабрь 2019 г.

A:
Oui, quand vous avez besoin du stack du S3900-24T4S, vous pouvez combiner les 4x10G SFP+, puis utiliser les ports 27 et 28 pour le stack et relier les ports 25 et 26 au serveurs et pc. Quand vous n'avez pas besoin de stack, tous les 4 ports 10G SFP+ peuvent être reliés aux switchs, routeurs, serveurs, pc et d'autres équipements. От FS на 6 декабрь 2019 г.
Q:
Can I combine the 4x10G SFP+ to use 2 ports for stacking and 2 port to hookup servers and nas? От Aldrich.Thiel на 26 ноябрь 2019 г.

A:
Yes, for the S3900-24T4S, you can combine the 4x10G SFP+ to use 2 ports for stacking and 2 ports to connect with servers and nas. When the stack is not needed, all four ports can connect with switches, routers, servers, and other devices. От FS на 27 ноябрь 2019 г.
