Shortages pressure community distributors into inventive product redesigns


Oct 4, 2022

Provide chain issues have triggered most main networking gamers corresponding to Cisco, Juniper, Arista, and others to revamp or re-engineer some merchandise in an try to beat element shortages and ship merchandise to clients.

Lead instances for some routers, switches and different gear is already delayed properly past six months. Retooling to get {hardware} out the door can add is personal delay and put further stress on engineers trying to reshape issues like energy provides and board-level options with out inflicting main issues themselves.

And from all accounts, it’s the multitude of smaller, considerably older elements of switches and routers which might be inflicting probably the most issues.

Talking at a Goldman Sachs convention this month, Arista CEO Jayshree Ullal mentioned that if there’s a commonality amongst semiconductor shortages it’s older 100-nanometer and bigger chips which might be utilized in issues like analog and solid-state units or energy converters.

“Technically, the fab capability and the supply of that must be simpler, however proper now, there’s a scarcity even there,” Ullal said.  “And there are additionally quite simple logic elements—like energy controllers, ICs [integrated circuits], AD/DA [analog to digital and vice versa] converters, logic units—that aren’t mainstream connectivity, however then you definately nonetheless want them to run to construct your whole system. So, it’s right down to 10 to twenty elements which might be quite simple, which might be inflicting us the best scarcity.”

The ‘golden screw’

Certainly it’s that problem inflicting probably the most issues throughout the {industry}.

“If any of the elements is lacking, the product can’t ship. Corporations can have 99 out of 100 elements to complete a product, however the one scarcity can cease manufacturing and maintain the product from being shipped. That’s the golden-screw phenomenon [one ideally perfect, small bolt that could finish a product] that producers are speaking about,” mentioned Sameh Boujelbene, senior director at Dell’Oro Group.

This varies by vendor and by merchandise as they need to make a judgment name on which elements can be probably the most constraining issue (i.e with the longest lead instances). What we heard about just lately are analog built-in circuits for energy provides however there definitely might be others,” Boujelbene mentioned. “The constant suggestions we now have been getting over the current quarters is that it’s presently impacting extra downstream commodity elements.”

“Every half for every gadget has a separate story, and we’ve seen some suppliers which might be attempting to extend capability, however don’t have entry to gear or they’re ready for orders which might be additionally constrained by semiconductors. So  the challenges are throughout the board and really particular to every gadget,” Ullal mentioned in a monetary name earlier this 12 months.

This contains forcing enterprises to make their very own diversifications to navigate the shortages, and in some instances inflicting distributors to make a modifications to networking gear.

One Cisco government mentioned just lately: “What we began doing someday late final 12 months and positively the primary six months of  this 12 months is basically taking a look at redesigning elements which had been choked, attempting to take away these redesigns, and people redesigns take time.”

On the time Cisco mentioned certainly one of its switches and one wi-fi system had seen some redesign and provide was now getting higher, nevertheless it declined to be extra particular about which merchandise these had been. The truth is not one of the distributors contacted for this story needed to speak about particular redesigns or different modifications they might be making on account of provide chain issues.

What’s a redesign?

Redesigns usually concentrate on printed circuitboards the place the seller would possibly now want to make use of a element it usually wouldn’t as a result of say, its regular provider and backup suppliers don’t have the half, consultants say. So engineers want to determine learn how to make the connectivity pins and different items of these elements work on the board, design that into an current product after which guarantee they will repeat that in a means to assist meet demand.  

Conceptually, if it’s a rational engineering group, it might take a look at what the largest influence is from the fewest variety of modifications, mentioned one {industry} observer. Distributors should not going to alter each product, however they may take a look at merchandise which have probably the most influence. 

“The first focus has been round consolidating {hardware} designs wherever potential, in order that there’s extra element similarity, if not uniformity, between discrete gadget classes and courses. Typically that’s not potential, after all, nevertheless it must be pursued as a normal rule to simplify supply-chain procurement and to convey larger consistency to supply schedules,” mentioned Brad Casemore, analysis vp, Datacenter and Multicloud Networks at IDC. “Equally, if Cisco or one other vendor finds {that a} particular provider or half has been problematic, they’ll search design or provide alternate options.” 

For purchasers it must be reassuring to listen to that their suppliers are re-designing merchandise to accommodate totally different elements and diversify their provide chains. Boujelbene mentioned. “Some distributors had been additionally prepared to pay increased dealer and expediting charges to make sure on-time product deliveries to their clients.”

For higher or worse, virtually all main vendor have used brokers, and paid a better value to acquire hard-to-get elements. However the concept is similar: Distributors can both construct a product or get elements from brokers with some slight modifications that clients most likely don’t care about. Or they will look ahead to the availability chain to settle and take supply when issues are extra out there, consultants mentioned.

Fewer ASICs?

One of many potential outcomes of the availability scarcity and system redesign could also be discount in use of {custom} chips and ASICs present in some Cisco, Juniper, Excessive, and different gear, consultants mentioned.

“Each vendor has just a few chips right here and there that they’re attempting to supply or get another for and, I’d speculate that what they is perhaps taking a look at doing was altering out among the {custom} chips that they had developed and virtually definitely can’t produce in home for extra commonplace {industry} chips,” mentioned Tom Nolle, president of CIMI Corp. “The entire custom-chip factor was, for distributors, a little bit of a PR play.  Business silicon from corporations like Broadcom can be a greater and cheaper choice, long-term, and for the purchasers it might probably find yourself higher, too.”

One other consequence, has been an uptick in gross sales of software program and digital type components for community features, corresponding to utility supply controllers, IDC’s Casemore mentioned.   ADCs are community home equipment that may bolster efficiency and safety of cloud functions.  

“Our assumption is that that is partly as a result of larger availability of industry-standard {hardware} versus fixed-function {hardware} home equipment,” Casemore mentioned.  “Equally, multivendor automation and orchestration programs, in addition to open-source networking software program (corresponding to SONiC—the open-source community working system), has skilled a gross sales enhance.”

“In some instances, we now have famous that clients had been drawn to the larger flexibility and selection that such software program facilitates within the face of supply-chain problems,” Casemore mentioned.
