Cisco’s M5 UCS servers take intent-based approach to data center

It's not the server -- it's the system. That's the word from Cisco as it rolls out its new, M5 generation Unified Computing System rack and blade servers, triggered by Intel's release of the Xeon Scalable Processor platform.Cisco's new servers use the Xeon Scalable processors -- unveiled Tuesday in New York -- to fuel performance as well as increase server density and throughput.  But the value in the UCS product family lies in how the hardware works with configuration management and optimization software to make data centers run at peak efficiency, company officials say.To read this article in full or to leave a comment, please click here

High Expectations for Low Precision at CERN

The last couple of years has seen a steady drumbeat for the use of low precision in growing numbers of workloads driven in large part by the rise of machine learning and deep learning applications and the ongoing desire to cut back on the amount of power consumed.

The interest in low precision is rippling through the high-performance computing (HPC) field, spanning companies that are running applications sets to the tech vendors that are creating the systems and components on which the work is done.

The Next Platform has kept a steady eye on the developments the deep-learning and machine-learning …

When is a Connected Route Not Used?

I ran into this situation on a recent project and thought it would make an excellent question on an exam. It could be worded something like this:

What is the behavior of a router or Layer 3 switch when a dynamic route is learned that partially overlaps with a directly connected network?

a. The router reboots
b. The network reboots
c. That’s um-possible
d. None of the above

The answer, of course, is “d” but the specifics of what does happen is what’s interesting. First, this is the scenario I’m trying to describe in the question above:

R12#show ip route
...
Gateway of last resort is not set

      10.0.0.0/8 is variably subnetted, 6 subnets, 3 masks
D        10.1.14.0/24 [90/1024640] via 123.1.1.14, 00:14:37, Ethernet0/1
C        10.10.10.0/24 is directly connected, Ethernet0/0
L        10.10.10.12/32 is directly connected, Ethernet0/0
D        10.10.10.64/26 [90/1024640] via 123.1.1.14, 00:14:05, Ethernet0/1

R12 has a directly connected network 10.10.10.0/24 on its e0/0 interface. It has also learned a route for 10.10.10.64/26 via an EIGRP neighbor on its e0/1 interface. We can see both networks Continue reading

LockPoS Joins the Flock

While revisiting a Flokibot campaign that was targeting point of sale (PoS) systems in Brazil earlier this year, we discovered something interesting. One of the command and control (C2) servers that had been dormant for quite some time had suddenly woken up and started distributing […]

Episode 7 – Extending Layer 2

There’s plenty of debate in the networking community about the merits of extending layer 2 networks, when you should do it, how you should do it, what pitfalls you should avoid, and what benefits you should expect. Join us as our panel discuss the finer points of what you should consider when you are considering extending layer 2 in your network.

What is hyperconvergence?

Hyperconvergence is an IT framework that combines storage, computing and networking into a single system in an effort to reduce data center complexity and increase scalability. Hyperconverged platforms include a hypervisor for virtualized computing, software-defined storage, and virtualized networking, and they typically run on standard, off-the-shelf servers. Multiple nodes can be clustered together to create pools of shared compute and storage resources, designed for convenient consumption. The use of commodity hardware, supported by a single vendor, yields an infrastructure that's designed to be more flexible and simpler to manage than traditional enterprise storage infrastructure. For IT leaders who are embarking on data center modernization projects, hyperconvergence can provide the agility of public cloud infrastructure without relinquishing control of hardware on their own premises.To read this article in full or to leave a comment, please click here

Intel tightens data-center grip with Xeon Scalable Processor platform

Make no mistake: Intel's Xeon Processor Scalable Family, based on the company's Skylake architecture, is about much more than revving up CPU performance. The new processor line is essentially a platform for computing, memory and storage designed to let data centers -- groaning under the weight of cloud traffic, ever-expanding databases and machine-learning data sets -- optimize workloads and curb operational costs.In order to expand the market for its silicon and maintain its de facto processor monopoly in the data center, Intel is even starting to encroach on server-maker turf by offering what it calls Select Solutions, generally referred to in the industry as engineered systems -- packages of hardware and software tuned to specific applications.To read this article in full or to leave a comment, please click here
