PLUMgrid brings on Cisco vet for network virtualization push

As it preps its go-to-market plans, the semi-stealthy startup brings another former Cisco product whiz aboard to lead engineering. Lele Nardin spent 15 years at the networking leader and was most recently SVP of engineering at Ericsson Silicon Valley.

Today in Cloud

Hot on the heels of VMware’s $1.26 billion acquisition of Nicira, Oracle said it will buy Xsigo for its software-defined networking (SDN) technology. SDN gear does to the network what VMware did to servers. It virtualizes the hardware and gives control to a software application, thereby managing traffic loads in a more flexible and efficient way. The challenge for users adopting SDN technology is to ensure that network policies on the regular network are in synch with virtual switches. For example, a virtualization admin sets policies on the vSwitch; the virtual machine moves off that server. Suddenly it’s using a regular switch where the policies are different and the application breaks. Much like the early days of server virtualization, admins will need to consider how virtualization impacts their total environment to avoid causing unnecessary disruption to services.

Oracle snaps up Xsigo for SDN smarts

If there was any doubt that software-defined networking (SDN) expertise is a hot ticket, Oracle’s planned acquisition of Xsigo, coming on the heels of VMware’s blockbuster $1.26 billion buy of Nicira, should erase it once and for all.

What’s Nicira? Read this and find out.

Nicira, the not-so-stealthy startup working in the network virtualization space was “outed” Monday by the New York Times as a secret startup pursuing the next hot trend in computing. But the article overstated Nicira’s secretiveness and perhaps its role as network virtualization hits the mainstream.

Backblaze vs. CrashPlan: Mac Backup Smackdown, Round 2

Online backup companies know that once you pay for the painstaking initial data dump, you’ll likely stay a customer long-term, because of convenience. But could unique features and attractive pricing convince you to switch? Today we turn to Backblaze and CrashPlan to find out.

How to Use Google for Calendars But Yahoo! for Mail, Contacts on iPhone

My post last week about merging Google Contacts generated a related question from Dave Zatz, because although he’s very content with Yahoo! (s yhoo)for mail and contacts, he’s interested in using Google Calendar (s goog) for events on his iPhone (s aapl). Surely you can’t mix and match among these on a single device, right? Actually, it turns out that you can do this thanks to the magic of Google Sync.

Virtualized I/O Takes Cloud Computing to the Next Level

logoThe folks behind PrimaCloud, a cloud computing and storage product that offers a service-level agreement that it claims delivers 99.99 reliability (that means it can go down 53 minutes each year), said today it will save $1 million by virtualizing its network and will spend 50 percent less to deliver its high reliability cloud. The company has installed boxes from Xsigo Systems that sit between the servers and switches and create a cloud through which the network traffic from the virtual machines loaded on the servers is routed. The network can handle traffic destined for other servers or for the storage network without requiring separate cables. Read More about Virtualized I/O Takes Cloud Computing to the Next Level

Xsigo Raises Money for Virtual I/O

Stack_Comparison_HorizXsigo today said it’s raised an undisclosed amount of venture capital from Kleiner Perkins Caufield & Byers, Greylock Partners, Khosla Ventures and North Bridge Venture Partners to support sales of its I/O virtualization appliance. Several filings submitted to the California Department of Securities show that back in April, the San Jose, Calif.-based startup had raised as much as $51 million, but Jon Toor, VP of marketing for Xsigo, declined to comment on either amount. Xsigo’s appliance sits inside a rack of virtualized servers and manages the way the virtual machines on those servers talk to one another, the network and the storage infrastructure. The Xsigo appliance works with any hypervisor, network and storage type. Read More about Xsigo Raises Money for Virtual I/O

Next Up: I/O Virtualization?

Austin, Texas-based startup NextIO has scored $18.8 million in a third round of funding, bringing the I/O virtualization systems maker to almost $40 million in total venture capital raised since 2003. It’s attacking one of those nitty-gritty technical problems in data centers and tossing around today’s favorite buzzword to do it.

NextIO makes chips and software to tackle I/O virtualization for the PCI Express protocol. Virtualized I/O allows a group of servers and/or storage systems to run Ethernet, FibreChannel, InfiniBand or whatever other flavor of interconnect technology through one box. This makes it easier to manage a network without having to map each server to a set endpoint. NextIO expects to ship products this year to OEMs that make servers and storage systems.

It’s not alone in attacking aspects of I/O virtualization. Others include Neterion, NetXen, 3Leaf, Xsigo and even some 10Gig-E players who have added I/O virtualization capabilities such as Solarflare Communications are trying to bring virtualization across the data center.
