The Convergence Or Divergence Of HPC And AI Iron

Based on datacenter practices of the past two decades, it is a matter of faith that it is always better to run a large number of applications on a given set of generic infrastructure than it is to have highly tuned machines running specific workloads. Siloed applications on separate machines are a thing of the past. However, depending on how Moore’s Law progresses (or doesn’t) and how the software stacks shake out for various workloads, organizations might be running applications on systems with very different architectures, either in a siloed, standalone fashion or across a complex workflow that links the …

Worth Reading: Journey into the hybrid cloud

“In the cloud” is more now than just a phrase that describes a feeling. Although the cloud began as a vision, over the past decade it has become an integral part of everyday business decisions, even being evaluated for an enterprise’s most critical high-value operations. Thanks to the public cloud, many startups find it quick and easy to set up their initial operation and product-development cycles. Some, such as Uber and Airbnb, even go to market entirely in the cloud. —The Data Center Journal

Linux 4.11 kernel extends packet sampling support

Linux 4.11 on Linux Kernel Newbies describes the features added in the April 30, 2017 release. Of particular interest is the new netlink sampling channel:
Introduce psample, a general way for kernel modules to sample packets, without being tied to any specific subsystem. This netlink channel can be used by tc, iptables, etc. and allow to standardize packet sampling in the kernel commit
The psample netlink channel delivers sampled packet headers along with associated metadata from the Linux kernel to user space. The psample fields map directly into sFlow Version 5 sampled_header export structures:

netlink psamplesFlowDescription
PSAMPLE_ATTR_IIFINDEXinputInterface packet was received on.
PSAMPLE_ATTR_OIFINDEXoutputInterface packet was sent on.
PSAMPLE_ATTR_SAMPLE_GROUPdata sourceThe location within network device that generated packet sample.
PSAMPLE_ATTR_GROUP_SEQdropsNumber of times that the sFlow agent detected that a packet marked to be sampled was dropped due to lack of resources. Agent calculates drops by tracking discontinuities in PSAMPLE_ATTR_GROUP_SEQ
PSAMPLE_ATTR_SAMPLE_RATEsampling_rateThe Sampling Rate specifies the ratio of packets observed at the Data Source to the samples generated. For example a sampling rate of 100 specifies that, on Continue reading

BGP Configurations on HP Routers

Today I am going to talk about the BGP configurations on the HP routers. I already posted the articles on the BGP configurations earlier where i defined the basic configurations on the Cisco and Juniper routers. Apart from these configurations I already put the basic information of the BGP as well. Below are some of the articles for which you can refer to study yourself step by step.

BGP Basics
BGP basics on Juniper Routers
BGP configurations on Cisco routers

Today I am going to have the basic configurations on HP routers with the topology. Below is the basic topology and the basic BGP configuration as below. The Topology and the IP addresses used here are only for the demo purposes and has no relevance with any of the live or enterprise networks.

Below is the demo topology showing the use of the HP routers where BGP is configured in the MPLS environment. This is just a example to showcase the topology. I will come up with the configurations on HP routers in the MPLS environment in later stage. As of now first we need to talk about the basic BGP on the HP routers and step by step we Continue reading

Microsoft introduces Azure Stack, its answer to OpenStack

Microsoft has taken the wraps off Azure Stack, its take on hybrid cloud infrastructure and response to the popular OpenStack open-source cloud computing package. Azure Stack will begin shipping in September.Azure Stack was originally designed as a software-only product, much like OpenStack. But Microsoft has decided to add integrated hardware turnkey solutions from its certified partners such as Dell EMC, HPE, Lenovo, Cisco and Huawei.Microsoft first announced Azure Stack at the Ignite Conference in 2015 and formally introduced it at the Inspire conference in Washington, D.C.Azure Stack is basically the same APIs, tools and processes that power Azure, but it’s intended to be hosted on-premises in private cloud scenarios. By offering the same platform and tools both on-premises and in Azure, the company promises consistency and ease of deployment, whether it’s hosted locally or in the cloud.To read this article in full or to leave a comment, please click here

Viptela Cloud onRamp optimizes cloud access

Over the past few years, SD-WANs have become the Kardashians of the tech industry. That is, it’s hard to go anywhere or talk to anyone without the topic of SD-WANs coming up. Unlike the Kardashians, SD-WANs deserve this level of attention, since the technology is useful by lowering the cost of running a WAN and improves application performance. However, for all the hype and chatter about the topic, its primary focus has been to improve connectivity to branch offices.It’s been well documented on this site and others that the cloud is not only mainstream but also the preferred strategy for many organizations, so a WAN must not only address connectivity to branch offices but also cloud services.To read this article in full or to leave a comment, please click here
