By: Bill Kleyman July 23rd, 2013. 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. . ” [.].
By: Jason Verge July 23rd, 2013. They manage dedicated firewalls for us, but as far as loadbalancers we use the cloud. I wasn’t sure cloud loadbalancing would be right, for example, but they showed us the numbers. July 2013 (144). June 2013 (164). May 2013 (165). April 2013 (179).
By: Industry Perspectives July 17th, 2013. The user level elements that are managed within such an IaaS cloud are virtual servers, cloud storage and shared resources such as loadbalancers and firewalls. July 2013 (144). June 2013 (164). May 2013 (165). April 2013 (179). March 2013 (167).
The network industry has focused on protocols for a long time because of the need interoperate hardware devices between vendors. The Second are is the higher level layers such as loadbalancing. If it’s happening at the application level now then why continue to add functionality at the hardware layer?
Recep will cover the hardware side of ONP; Gershon will cover the software side of ONP (referred to as ONS). ONP fits into this picture by performing VTEP functions in hardware (at line rate). Some of these services naturally should run on the top-of-rack (ToR) switch, like loadbalancing or security services.
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 loadbalancers? What about NX-OS, JUNOS, or EOS?
The ability to virtualize the network devices such as firewalls, IPS and loadbalancers also means that these once physical devices that have discrete interfaces can be controlled by software. This is where partnerships from both hardware vendor and existing software management solutions.
Essentially the punchline is this: Weve taken the most commonly-purchased hardware configuration and management tools used by mission-critical IT Ops, and integrated them into a single product with a single GUI that you can install and use in ~ 1 day. If you dont believe Dell hardware is ready for the Data Center, then think again.
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, loadbalancing, and storage connections - Sometimes referred to as "Infrastructure 2.0". a Fabric), and network switches, loadbalancers, etc.
Existing physical IO but with address hardware-based mapping/virtualization (e.g. Workloads, NICs, HBAs, networking addressing and storage connections (complete with fabric-based loadbalancing) can all be cloned… starting with the IO and networking profiles, made possible through IOV. ► 2013. (10).
The next step is to define in software the converged network, its switching, and even network devices such as loadbalancers. Provisioning of the network, VLANs, IP loadbalancing, etc. ► 2013. (10). The result is a "wire-once" physical network topology, but with an infinitely reconfigurable logical topology.
Capital cost – if you count all of the separate hardware components they’re trying to manage. That last bullet, the thing about hardware components, is also something to drill down into. And I mean I/O components like NICs and HBAs, not to mention switches, loadbalancers and cables. ► 2013. (10).
True, both have made huge strides in the hardware world to allow for blade repurposing, I/O, address, and storage naming portability, etc. However, in the software domain, each still relies on multiple individual products to accomplish tasks such as SW provisioning, HA/availability, VM management, loadbalancing, etc.
Servers/Hardware. In any case, this article by Frank Denneman on Storage DRS loadbalancing frequency might be useful to you. OpenStack Summit 2013: Building HA OpenStack with Puppet in 20 Minutes. Reading these early OpenFlow meeting notes (via Brent Salisbury, aka @networkstatic on Twitter) was very fascinating.
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 loadbalancing, etc.), ► 2013. (10). and storage connectivity (LUN mapping, switch control) are all abstracted and defined/configured in software.
