Senza Fili Leveraging802.16e Wi Max 091111Monica Paolini
License-exempt spectrum bands make it possible for operators who do not have access to licensed spectrum to deploy wireless broadband networks. Traditionally vendors have developed specific solutions for license-exempt operators, often based on proprietary technology that limits the flexibility and upgradability of their networks.
With Institute of Electrical and Electronics Engineers (IEEE) 802.16e WiMAX, license-exempt operators have access to the most advanced wireless broadband technology on the market today and can take advantage of the same performance, ecosystem, and volume of scale that incumbent, nationwide wireless operators with licensed-spectrum can.
While often positioned as a mobile broadband technology that operates in licensed bands, 802.16e WiMAX can also support fixed and nomadic services, and vertical applications in a range of frequencies up to 6 GHz, including license-exempt bands such as the 5.x GHz band and, in the US, the lightly licensed 3.65 GHz band.
As 802.16e WiMAX products for license-exempt bands are introduced in the market, operators need to know what the value proposition of using 802.16e WiMAX compared to alternative solutions is. How do they stand to gain from a technology that was developed to support mobility? Do they need the extra features that 802.16e WiMAX offers?
We just finished a white paper that addresses these questions by looking at operators' requirements and how 802.16e WiMAX meets them.

CONTAINERIZED SERVICES ORCHESTRATION FOR EDGE COMPUTING IN SOFTWARE-DEFINED W...IJCNCJournal
As SD-WAN disrupts legacy WAN technologies and becomes the preferred WAN technology adopted by corporations, and Kubernetes becomes the de-facto container orchestration tool, the opportunities for deploying edge-computing containerized applications running over SD-WAN are vast. Service orchestration in SD-WAN has not been provided with enough attention, resulting in the lack of research focused on service discovery in these scenarios. In this article, an in-house service discovery solution that works alongside Kubernetes’ master node for allowing improved traffic handling and better user experience when running micro-services is developed. The service discovery solution was conceived following a design science research approach. Our research includes the implementation of a proof-ofconcept SD-WAN topology alongside a Kubernetes cluster that allows us to deploy custom services and delimit the necessary characteristics of our in-house solution. Also, the implementation's performance is tested based on the required times for updating the discovery solution according to service updates. Finally, some conclusions and modifications are pointed out based on the results, while also discussing possible enhancements.

The 2019 Storage brand leader surveys cover 14 storage products. This report includes the results of IT Pro voting for six categories of brand leadership for each service: Market, Price, Performance, Reliability, Innovation, and Service & Support.
AWS is estimated to be the #3 enterprise storage vendor by revenue in 2018, with storage revenue estimated between $1.1-1.486 billion in Q4 2018. By extrapolating AWS's 52% market share of the IaaS market to the storage-as-a-service market, and estimating that 15-20% of AWS's revenue comes from storage, AWS is calculated to have overtaken traditional storage vendors by revenue. If AWS maintains 35-45% annual growth, it is projected to become the #1 storage vendor by 2020, with over $3 billion in storage revenue, cementing its position as a top storage leader through sustained large investments in R&D.
AWS #3 Storage Vendor in 2017 | #1 in 2020IT Brand Pulse
This IT Brand Pulse industry brief uses crowd-sourced data about storage and cloud revenues to estimate the size and ranking of the AWS storage business. The bottom line is AWS is the #3 ranked storage vendor in 2017 and will be #1 in 2020.
The document discusses how server and storage utilization has changed with the adoption of virtualization, noting that a survey found over half of small to medium companies were using VMware hypervisors by 2016, especially among larger companies. It also explains how vMotion traffic can either share the Ethernet network with application servers or be isolated to a dedicated FC-SAS storage network. Finally, it lists some VMware and ATTO solutions related to using direct attached storage to create a SAN.
The document discusses how small to medium businesses have swung between using direct-attached storage (DAS) and storage area networks (SANs) for their VMware environments. It provides an example of a construction firm, Torcon, that converted their DAS setup into a SAN using ATTO technology to save costs and extend the usable life of their servers and storage. The conversion took less than three hours and provided benefits like isolated storage networking and easier expansion capacity. The document advocates that SAS-based SANs provide performance and flexibility comparable to fibre channel SANs at a lower cost that is suitable for cost-conscious small to medium businesses.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
Getting the Most Out of ScyllaDB Monitoring: ShareChat's TipsScyllaDB
ScyllaDB monitoring provides a lot of useful information. But sometimes it’s not easy to find the root of the problem if something is wrong or even estimate the remaining capacity by the load on the cluster. This talk shares our team's practical tips on: 1) How to find the root of the problem by metrics if ScyllaDB is slow 2) How to interpret the load and plan capacity for the future 3) Compaction strategies and how to choose the right one 4) Important metrics which aren’t available in the default monitoring setup.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
This talk will cover ScyllaDB Architecture from the cluster-level view and zoom in on data distribution and internal node architecture. In the process, we will learn the secret sauce used to get ScyllaDB's high availability and superior performance. We will also touch on the upcoming changes to ScyllaDB architecture, moving to strongly consistent metadata and tablets.

Server Virtualization is Leading the Way to Software Defined Data Centers
This industry brief is about a renaissance in how virtual machines are networked. To help the reader understand why
the industry is moving out of the dark ages, we first examine the driving force behind the new technology: hyperscale
service providers and software define data centers.
Necessity is the mother of invention, and cloud service providers invented dozens of new information technologies to
operate profitably while deploying millions of virtual machines dispersed geographically around the world. Virtual
networking for VMs is pervasive in hyperscale data centers because it is a core capability for meeting requirements
for cost-effective server virtualization at scale.
Renaissance in VM Network Connectivity in the Enterprise
The same virtual networking technology Amazon and Microsoft Azure use to achieve QoS, greater workload
portability and lower cost, is now available to the masses. Read this report to learn more about how to design more
efficient network connectivity for your virtualized servers.
Executive Summary
Originally invented to increase the utilization of server hardware in a single data center, server virtualization now underpins expanding
workload portability for computing across geographically dispersed cloud data centers.
Workload Portability
3. Document # INDUSTRY2015005 v4, July, 2015 Page 3
Software Defined Data Center: Server Virtualization Leading the Way
Approximately 80% of new workloads deployed in enterprise data centers are hosted on virtual machines, otherwise
known as software defined servers. Hyperscale data centers have taken that concept two steps further with software
defined storage and software defined networks. Almost every enterprise IT organization is at some stage of
transforming their infrastructure into private clouds with a software defined data center architecture allowing them
to efficiently manage virtual resources across multiple data centers.
The Model for Data Center Efficiency
Traditional Data Center
In a typical enterprise data center, IT
organizations have broken free from server
vendor lock-in with hypervisors which can
virtualize any server using an x86 processor.
However, most networking and storage
environments remain silos of vendor-
specific hardware and software.
Software Defined Data Center
In software defined data centers, IT
organizations have transformed their
networking and storage infrastructure from
vendor-specific hardware into open-source
based software and hardware. This is
accomplished by deploying apps on virtual
machines and industry standard servers—all
under the centralized control of a cloud
operating system such as OpenStack.
Today, over 80% of new workloads in the enterprise are deployed on virtual machines, and the benefits of server
virtualization have signaled IT organizations it’s time to consider a migration to software defined networking and storage.

10GbE Server Connectivity
The penetration of server virtualization has reached the point where almost all new workloads are running on virtual
machines, IT pros are comfortable with tier-1 apps running on virtual machines, and VM density is increasing to the
point where network I/O has become a critical issue.
This aggregation of VMs, workloads and I/O explains why, after ten years on the market, the deployment of 10GbE
network connectivity has become a necessity. This trend is also driving adoption of virtual networking technology to
partition 10GbE ports and shape the virtual network links on a per-VM basis.
Trending Now in the SDDC
Emerging Virtualized Server Network Connectivity—10GbE NICs Partitioned into vNICs
Past Virtualized Server Network Connectivity—6 x 1GbE Ports
According to IT Brand Pulse surveys, a typical virtualized server has an average of six 1GbE ports configured and the only
network virtualization deployed is teaming. IT pros say the biggest issue with 1GbE is lack of performance, and the biggest
issue with upgrading to 10GbE is cost.
4Gb2Gb2Gb2Gb
4Gb1Gb4Gb1Gb
Port 1 vNICs
Port 2 vNICs
What’s trending in server network connectivity is the use of 10GbE NICs in combination with partitioning. The two together can
provide more bandwidth than a pair of teamed NICs, and offset the cost of 10GbE by replacing up to ten 1GbE NICs.
5. Document # INDUSTRY2015005 v4, July, 2015 Page 5
Less than Half of IT Pros are Virtualizing Network Connectivity to VMs
While the use of virtual NICs and virtual switches is pervasive in hyperscale data centers, less than half of enterprise IT
pros surveyed said they will deploy these virtual networking technologies in 2015.
This indicates there is an opportunity for many enterprise IT organizations to lower the cost of their virtualized servers
by partitioning physical networks into many virtual networks, and to improve the performance of their applications by
implementing QoS to guarantee bandwidth to select virtual networks and workloads.
More than Half Prefer to Use a Hypervisor for Virtual Network Management
Over half of IT pros surveyed indicated they would prefer to use a hypervisor to manage their virtual networks, almost
twice as many who preferred to manage virtual networks through a switch.
This indicates a preference for a virtual networking management platform which is common to all servers.
All are Balancing the Benefits of Virtual Networks with Available Resources
Implementing virtual networks is not trivial. Busy IT pros continue to map physical network ports to their VMs because
they don’t have the time and/or budget to learn the technology and evaluate products. Even large enterprises with
thousands of VMs must balance the benefits of virtual networks with available resources.
New approaches to virtual networking are needed which will make adoption easier for small enterprises, and lower the
cost for large enterprises.

do you expect to evaluate or deploy in 2015?
6. Document # INDUSTRY2015005 v4, July, 2015 Page 6
Guaranteed Quality of Service for Specific VMs and Workloads
Dedicating physical 10Gb network ports to VMs can get expensive. That’s why a killer app for virtual networks is to
partition the physical ports and guarantee bandwidth to the most important workloads. The chart below shows the
performance of a SQL workload, which was sharing a physical 10GbE LOM port, was degraded when there was heavy
I/O contention. In contrast, performance was maintained when a QL3400 NIC was configured to prioritize SQL traffic
on one partition, guaranteeing bandwidth to the SQL workload.
Fine Tuning Virtual Networks by Traffic Type
Shaping virtual networks by making use of granular controls for ports and resource pools can further increase
application performance and availability. The diagram below shows examples of how server admins can configure
virtual ports for predefined resource pols with VMware ESX Network I/O Control (NIOC)
Killer Apps for Virtual Networks
Admins may configure virtual port
groups with these capabilities:
Isolation - Ensures traffic isolation so
that a given flow will never dominate
over others, preventing drops.
Shares - Allows flexible networking
capacity partitioning to help users
deal when flows compete for the
same resources.
Limits - Enforce traffic bandwidth
limit on the overall VDS set of
dvUplinks.
Load-based Teaming - Efficiently
uses a VDS set of dvUplinks for net-
working capacity.
IEEE 802.1p tagging - Tags outbound
packets from the vSphere host for
proper handling by physical network
resources.
NIOC classifies traffic into these
predefined resource pools:
VMware vSphere vMotion
iSCSI

Use any Network Partitioning Tool to Consolidate NIC and Switch Ports, and to
Guarantee Bandwidth to Critical Apps (QoS)
Considering that about two thirds of enterprises have not implemented vSwitches and vNICS, most enterprises can
lower the cost of their virtual server network connectivity and improve application performance by taking the first
step with their choice of switch, hypervisor, operating system or NIC tools for basic partitioning and QoS.
Cut Costs by Sharing High-Performance NIC and Switch Ports
It is common for server racks with high VM densities to use high-performance 10GbE NIC and switches to ensure
there is sufficient bandwidth. The quantity and cost of 10GbE links can be reduced by virtualizing ports to increase
utilization. The chart below shows that for 50 servers connected via 10G Base-T, a savings of $75,200 can be realized
by increasing utilization of NICs resulting in elimination a single NIC per server.

Keep all NIC Ports Available for Data Traffic with Hyper-V
There are numerous articles about Hyper-V networking best practices. One best practice which is mentioned
frequently is that you should separate Hyper-V QoS management traffic from Virtual Machine traffic on the physical
network.
NIC-based QoS Enables Partitions on All Ports
A new best practice is to use NIC-based network partitioning (NPAR) for QoS. Because NIC firmware is not accessible
in the same way as operating system resident software, you can mix VM and QoS traffic without compromising
network security. You can also buy-back high-performance network ports which otherwise would be dedicated to
management traffic. You could achieve a cost savings of over $30,000 by implementing this new best practice.

Keep CPU Resources Available for VM Workloads
Many server administrators underestimate the amount of CPU require to process network protocols which are not
offloaded by some NICs. For example, NICs from Intel which use server CPU to “on-load” iSCSI, VXLAN and NVGRE
protocol processing, can steal a third of your server’s processing power.
The Cost of On-Loading Network Management & Protocol Processing
The more expensive your server, the more expensive it is to on-load network protocol processing. The chart below
shows the cost of on-loading the iSCSI processing shown above for 20, 50 and 100 servers which each cost $20,000.

Consolidate Virtual Networking
It is estimated that only 15% of IT organizations who are using hypervisors, use a single hypervisor. In addition, most
IT organizations which have deployed virtual networking, are using virtual networking tools from their switch
vendors. One way to improve the efficiency and lower the total cost of your virtual networks, is to consolidate your
virtual networking tools where possible.
By Layering Virtual Networking Services on a Common Platform
A new approach for connecting VMs with virtual networks is to layer services on NIC-based partitions. This approach
allows admins to standardize on a set of virtual network partitioning tools which are hypervisor and switch
independent, and whose virtual network settings migrate seamlessly along with the VMs.

QLogic Eats its Own Dog Food
Until recently, QLogic IT knew they had extra processing power in their 8-node SharePoint cluster, but did not have a
way of using the processing power without risk of degrading SharePoint performance. The IT solved the problem by
deploying the company’s own NIC-based network partitioning (NPAR). NPAR virtual network allows the CPU
resources to be shared by production and dev applications, while guaranteeing bandwidth to the production apps.
The result is QLogic IT has one less cluster and two less servers to manage and keep under service contracts.

IT was able to move dev apps onto the
SharePoint cluster because they could guarantee
bandwidth to production workloads.

#2 in 10GbE NICs for the Enterprise
QLogic has a broad portfolio of high-performance Ethernet adapters for enterprise servers—all of which are designed
to deliver a rich set of virtual networking services for virtual machines. For basic LAN and NAS connectivity, the
company offers the 3200 Series and 3400 Series. If you want to consolidate LAN and SAN connectivity to servers,
QLogic offers the 8300 Series and 8400 Series converged network adapters with full offload of the CPU-hungry iSCSI,
FCoE or Fibre Channel protocols. The 8300 Series can even by converted to a native 16Gb Fibre Channel HBA.
#1 at 25GbE
QLogic has publically stated that OEMs are qualifying their 25G and 100G converged network adapters, so I fully expect
QLogic to be first to market in 2016 with products which are generally available from OEMs. The new adapters will
open up server connectivity for applications that need more bandwidth, and will be a cost-effective alternative to
multiple 10G adapters as the price of 25 G optical transceivers and cables drop.

For typical IT organizations using hypervisors from VMware and Microsoft, the following is a checklist of things to
consider before implementing or optimizing virtual networks to your virtual machines. Each items represents an
opportunity for you to deploy server connectivity more efficiently and cost effectively.
□ (If You Haven’t Already) Implement Virtual Networks
The biggest opportunity to impact efficiency and reduce the cost your server networking is implement some type of
virtual network partitioning tool in the NIC, or hypervisor vSwitch. If sharing 10GbE ports can save one NIC and switch
port per server, the savings will add-up fast.
When 25GbE, 50GbE and 100GbE NIC ports emerge in 2016, implementing network partitioning will be required to
making full use of the bandwidth available on each port.
□ Use NIC-based Partitioning as a Virtual Networking Platform
If you really want to be efficient, consider using NIC-based partitioning because it is hypervisor and switch
independent. It will allow you to standardize on one partitioning tool which works with any hypervisor and vSwitch.
□ Offload Network Protocol Processing
CPU vendors will tell you that on-loading network protocol processing is not a big deal, because they sell processors. It
really is a big deal because it can silently eat-up a third of the server CPU you bought to support VMs and their
workloads. Use NICs which offload iSCSI, FCoE, NVGRE and VXLAN and you will preserve your investment in processing
power for business apps. This issue is especially important if you are using iSCSI or FCoE interface storage which is I/O-
intensive. Don’t giveaway a third of your CPU power if you can avoid it by simply deploying a NIC with offload.

The Bottom Line
The next wave of server virtualization for hyperscales centered around virtualizing the network connections to better
scale and to lower costs. Those benefits are now available to the enterprise. Surprisingly, the humble NIC plays a key
role in the new era of software defined data center because it is the gateway to the industry standard servers which
host business and infrastructure apps, including NFV and software defined storage.
The bottom line is that selecting your NIC technology has suddenly became a strategic decision if you want to wring out
the efficiencies and cost savings enjoyed by the big hyperscales. Don’t settle for fast and dumb on-load NICs. Look for
fast and smart NICs which are designed from the ground up for virtual networking.
Recommendations
Estimate how much time and capital you would save if you implemented virtual networks.
Create a virtual networking strategy that extends from inside server to other data centers.
Standardize on a NIC platform which supports network partitioning (NPAR) and layer other services on top.
Start small and fail fast. Deploy QoS in a DevOps lab or in a non-critical production environment.
