Solarflare’s Open Compute Platform, Software-Defined, NIC Card

CTOvision

Solarflare adapters are deployed in a wide range of use cases, including software-defined networking (SDN), network functions virtualization (NFV), web content optimization, DNS acceleration, web firewalls, load balancing, NoSQL databases, caching tiers (Memcached), web proxies, video streaming and storage networks. Other capabilities include: Hardware Based Packet Telemetry. Hardware Based Security (ServerLock). Marty Meehan.

IDF 2014: Architecting for SDI, a Microserver Perspective

Scott Lowe

Once again this comes back to Intel’s rack-scale architecture work.) A traditional SRF architecture can be replicated with COTS hardware using multi-queue NICs and multi-core/multi-socket CPUs. Workloads are scheduled across these server/linecards using Valiant Load Balancing (VLB). Of course, there are issues with packet-level load balancing and flow-level load balancing, so tradeoffs must be made one way or another.

Is Cisco fighting a losing battle over SDN?

Virtualized Greek

This is different from the current software first movement in that Cisco’s approach is based on their hardware first view of the network. F5 – Security/Load Balancing. I’m wondering if Cisco is fighting a losing battle with their ACI approach to SDN.

Federation Solutions And The New IT Agenda

 ViPR is used to provision the desired storage service level (independently of underlying hardware) and a separate workflow is used to provision the desired data protection (e.g.     Although this is an explicit process today (sorry, no automated load balancing!)

When Using Cloud Computing to Replicate is the Right Idea

Data Center Knowledge

Whether it is redundant hardware or a private hot-site, keeping an environment up and running 99.99% (insert more 9’s here) of the time is a tough job. So, if one site should go down – users would transparently be balanced to the next nearest or most available data center. . About DCK.

David Holder walks through removing unused load balancer IP allocations in NSX-T when used with PKS. Servers/Hardware. Software company Agile Bits recently announced support for U2F-compatible hardware security keys in their 1Password product. Systango has this high-level overview of serverless application architecture along with some pros/cons, use cases, etc. Welcome to Technology Short Take #115!

Fountainhead: Differing Target Uses for IT Automation Types

Fountainhead

A specific angle I want to address here is that of infrastructure automation ; that is, the dynamic manipulation of physical resources (virtualized or not) such as I/O, networking, load balancing, and storage connections - Sometimes referred to as "Infrastructure 2.0". a Fabric), and network switches, load balancers, etc. And, a single virtualized switching node can present itself as any number of switches and load balancers for both storage and network data.

Fountainhead: Emergence of Fabric as an IT Management Enabler

Fountainhead

The next step is to define in software the converged network, its switching, and even network devices such as load balancers. Provisioning of the network, VLANs, IP load balancing, etc. Gartner and others agree - this is the next wave in data center architecture.

Romain Decker has an “under the hood” look at the VMware NSX load balancer. Servers/Hardware. This graphical summary of the AWS Application Load Balancer (ALB) is pretty handy. The series provides an introduction and overview of licensing (part 1), a review of architecture and hardware recommendations (part 2), an overview of data availability (part 3), and a discussion of fault domains (part 4).

What I Mean When I Say "Enterprise Storage" - Chuck's Blog

The architectural responses you'll typically find in enterprise storage arrays is a reflection of these demands: a minimum of two intelligent controllers, with a requirement to grow to far more as requirements expand. non-disruptive everything: hardware, software, configs, etc.

HPs BladeSystem Matrix architecture is based on VirtualConnect infrastructure, and bundled with a suite of mostly existing HP software (Insight Dynamics - VSE, Orchestration, Recovery, Virtual Connect Enterprise Manager) which itself consists of about 21 individual products.

IDF 2013: Future of SDN with the Intel ONP Switch Reference Design

Scott Lowe

Recep will cover the hardware side of ONP; Gershon will cover the software side of ONP (referred to as ONS). Recep talks about how the predominant architecture for network virtualization involves the use of overlay networks created and managed at the edge by virtual switches in the hypervisors. ONP fits into this picture by performing VTEP functions in hardware (at line rate). It is hardware switch independent. Learning NVP, Part 1: High-Level Architecture.

Fountainhead

Converged Infrastructure and Unified Computing are both terms referring to technology where the complete server profile, including I/O (NICs, HBAs, KVM), networking (VLANs, IP load balancing, etc.), From an architectural perspective, this approach may also be referred to as a compute fabric or Processing Area Network. skip to main | skip to sidebar.

Virtualizing Microsoft SQL Server on Windows Server 2012 #winserv.

IT Pros Rock!

In Windows Server 2012, HA is provided top-to-bottom starting from individual hardware components, and then progressing to server redundancy, application availability, and even entire datacenter resiliency. Network and Storage IO redundancy provided by integrated support for Network Load Balancing, NIC teaming, and Multi-path IO (MPIO). To minimize processor overhead on memory and IO intensive database workloads, leverage hardware that offers offload capabilities, such as.

On Network Virtualization and SDN

Scott Lowe

According to Martin, the term SDN originally referred to a change in the network architecture to include a) decoupling the distribution model of the control plane from the data plane; and b) generalized rather than fixed function forwarding hardware. What about virtualized load balancers? Is there a difference between network virtualization and Software-Defined Networking (SDN)? If so, what is the relationship between them? Is one a subset of the other?

Amazon EC2 Cluster GPU Instances - All Things Distributed

All Things Distributed

Building general purpose architectures has always been hard; there are often so many conflicting requirements that you cannot derive an architecture that will serve all, so we have often ended up focusing on one side of the requirements that allow you to serve that area really well.

CLDS006: Exploring New Xeon E5 Optimizations for 10 Gb Ethernet

Scott Lowe

As a provider, Expedient has to balance five core resources: compute, storage (capacity), storage (performance), network I/O, and memory. Using 1 GbE would have required too many ports, too many cables, and too many switches; 10 GbE offered Expedient a 23% reduction in cables and ports, a 14% reduction in infrastructure costs, and offered a significant bandwidth improvement (compared to the previous 1 GbE architecture).

First up is Brent Salisbury’s how to build an SDN lab without needing OpenFlow hardware. Not unsurprisingly, one of the key advantages of STT that’s highlighted is its improved performance due to TSO support in NIC hardware. Related to the bare metal provisioning work (see below under “Servers/Hardware”), Mirantis also detailed some bare-metal networking stuff they’ve done for OpenStack in relation to the use of bare metal nodes.

If you’d like to play around with Cumulus Linux but don’t have a compatible hardware switch, Cumulus VX is the answer. Servers/Hardware. Normally the hardware space is pretty boring (in fact, I’ve been considering removing it from the Technology Short Take series), but HPE decided to shake things up recently with its Synergy servers and “composable architecture”.
