0:12 the rise of 400g is changing the data

0:15 center landscape

0:17 data center operators driven by cloud

0:20 computing iot and more are accelerating

0:23 the product adoption of 100g to 400 g

0:28 today i have with me rugby bitker to

0:31 discuss the rising trend in data centers

0:34 across all theaters and market segments

0:37 with some a little more aggressive than

0:39 others

0:40 rugby it's nice to have you on the call

0:42 with me thank you arun such a pleasure

0:44 to be here so regulate as i mentioned we

0:47 are seeing growing adoption of 400 g in

0:50 the data centers

0:52 what are some of the motivations behind

0:54 the 100 g to 400 g transition

0:58 absolutely so we have seen a significant

1:01 uptick in the data center traffic due to

1:04 a few trends

1:05 uh first enterprises are moving their

1:08 on-prem services onto cloud

1:10 there's also a significant

1:12 uh amount of application traffic uh or

1:15 apt to have traffic in data centers uh

1:18 and the app services are also being

1:20 broken down into microservices

1:22 they are geographically distributed or

1:25 even sitting on

1:26 different clouds

1:28 another trend we've seen is you know

1:30 multiple new devices are connecting to

1:32 the internet for example iot devices and

1:36 this uptick in network traffic is

1:39 putting a huge strain on the uh data

1:42 center or cloud infrastructure

1:44 which is predominantly 40 gig and 100

1:47 gig

1:48 today

1:49 and that's why more and more data center

1:51 operators are you know waking up to the

1:53 idea of moving to 400 gig products uh to

1:56 compensate for that

1:58 um not just that uh there are there are

2:01 also some physical and mechanical

2:03 advantages of moving to 400 big products

2:08 with 400 gig uh as a choice of interface

2:11 you can get these the uh same form

2:13 factor but you can get four times uh the

2:16 throughput as a 100 gig port

2:19 and with the innovations in the power

2:21 efficiency of 400 gig optics the cost

2:25 per bit uh has gone significantly down

2:28 so that makes sense when you talked

2:30 about the the motivations behind

2:33 the transition

2:34 but can you also throw some light on the

2:36 use cases for 400 deployments in the

2:40 data centers absolutely so apart from

2:42 the physical and mechanical advantages

2:45 of 400 gig that we just talked about the

2:48 need for 400 gig really arises from the

2:51 speed of innovation that we see in tech

2:54 today

2:55 so 400 gig as a choice of interface is

2:58 quite

2:59 well suited for applications in

3:01 artificial intelligence deep learning

3:04 healthcare or even fintech that demand a

3:07 high throughput low latency lossless or

3:10 near lossless performance

3:12 if we talk about positioning uh 400 gig

3:15 platform just in terms of like uh you

3:17 know there was their position in the

3:19 network space or network infrastructure

3:22 they're very well suited for uh the

3:24 spine or super spine uh

3:27 layer where the requirement is fast

3:29 switching or even a border leaf

3:31 where you need that feature richness

3:34 or have a nice demarcation with your

3:36 network boundary

3:38 so can you talk about uh the juniper

3:41 400g data center product portfolio

3:44 that support these uh these use cases

3:46 that we just discussed

3:48 sure we have a robust portfolio uh in

3:51 the qfx product line the first uh i

3:54 wanna highlight is the 50 to 20 product

3:56 line which is optimized for fast

3:58 twitching and we also have the 5130

4:00 product line uh which is optimized to

4:03 host a rich feature set

4:05 to support some of the applications uh

4:08 that we just talked about

4:10 i also want to really highlight uh the

4:12 newest member of the qfx family which is

4:15 the 5700 product line

4:18 uh what's unique to this uh platform is

4:20 that it is the first uh

4:23 single pfe

4:25 uh

4:25 vertical slot qfx chassis that supports

4:29 uh speeds from you know 10 gig all the

4:31 way up to 400 gig with the

4:34 unidirectional throughput of 12.8 uh

4:37 tbps

4:38 this platform is also optimized uh to

4:41 host a number of fabric options uh

4:44 especially evpn vxlan and also storage

4:47 and timing features

4:49 which we are seeing a great uh you know

4:51 growing adoption uh these days so what's

4:54 special about the software running on

4:56 these platforms

4:58 that's a great question so the software

5:00 that's built into these platforms is an

5:03 evolved a newer version of junos

5:06 rightfully named juno's evolved

5:09 and with this software we are targeting

5:10 uh some of the major challenges faced by

5:13 data center operators

5:15 challenges like ease of upgrade ease of

5:18 fault isolation

5:20 maintaining a minimum downtime

5:22 ability to pull various

5:24 statistics and analytics

5:27 via telemetry

5:29 just to make intelligent decisions in

5:31 day-to-day network operations and this

5:33 is all possible because of the

5:35 componentized nature of juno's evolved

5:39 and we are very excited to roll it out

5:42 on some of the newer qfx series

5:44 platforms

5:45 um our platforms will also be integrated

5:48 into

5:49 appstra which is our network management

5:52 and automation offering

5:54 rugby thanks for joining me it's been a

5:56 pleasure talking to you

5:58 thank you arun it was great to share

6:00 some of the exciting things we are doing

6:02 at uh in the data center space at

6:04 juniper great thank you and thank you to

6:07 all our viewers
