Under the Covers of a Distributed Virtual Computing Platform – Built For Scale and Agility – via @dlink7, #Nutanix

I must say that Dwayne did a great job with this blog post series!! It goes into expelling the Nutanix Distributed File System (NDFS) that I must say is the most amazing enterprise product out there if you need a truly scalable and agile Compute and Storage platform! I advise you to read this series!!

Under the Covers of a Distributed Virtual Computing Platform – Part 1: Built For Scale and Agility

Lots of talk in the industry about how had software defined storage first and who was using what components. I don’t want to go down that rat hole since it’s all marketing and it won’t help you at the end of the day to enable your business. I want to really get into the nitty gritty of the Nutanix Distributed Files System(NDFS). NDFS has been in production for over a year and half with good success, take read of the article on the Wall Street Journal.

Below are core services and components that make NDFS tick. There are actually over 13 services, for example our replication is distributed across all the nodes to provide speed and low impact on the system. The replication service is called Cerebro which we will get to in this series.

This isn’t some home grown science experiment, the engineers that wrote the code come from Google, Facebook, Yahoo where this components where invented. It’s important to realize that all components are replaceable or future proofed if you will. The services\libraries provide the API’s so as newest innovations happen in the community, Nutanix is positioned to take advantage.

All the services mentioned above run on multiple nodes in cluster a master-less fashion to provide availability. The nodes talk over 10 GbE and are able to scale in a linear fashion. There is no performance degradation as you add nodes. Other vendors have to use InfiniBand because they don’t share the metadata cross all of the nodes. Those vendors end up putting a full copy of the metadata on each node, this eventually will cause them to hit a performance cliff and the scaling stops. Each Nutanix node acts a storage controller allowing you to do things like have a datastore of 10,000 VM’s without any performance impact… continue reading part 1 here.

No it’s not Billy Gibbons, Dusty Hill, or drummer Frank Beard. It’s Zeus and Zookeeper providing the strong blues that allow the Nutanix Distributed File System to maintain it’s configuration across the entire cluster. Read more…

Surprising Stats About Mobile Security

Another good article!!

Surprising Stats About Mobile Security

IT security and data protection are the top ranked challenges faced by many mobile IT asset managers. This was certainly brought to light in Mobile Enterprise’s IT headaches executive survey, and recent research from the International Association of IT Asset Managers (IAITAM) brings this to light as well.

When IAITAM asked: how do organizations handle mobility and security? Fifty five percent of respondents access the enterprise from a remote location during off hours and the same number can access enterprise information from any BYOD device. Yet only 60% of organizations track how, how long or who is accessing remotely.
Out of those employees who do access the enterprise remotely, slightly more than half use a secure key or digital pass, while 49% use a login name and password on a secure site. A little more than half (53%) of organizations surveyed have an intrusion protection system for deployed mobile units.

Lost/Stolen Devices Covered
Nearly 90% of respondents have a mobile device policy and process in place for lost, misplaced or stolen mobile devices. At the same time, little more than a quarter have real-time location system tracking on any/all mobile devices. Still, 56% say they are able to perform a remote wipe of all data.
Less than half (43%) will automatically replace a lost, misplaced or stolen device within a 24 to 48 hour period. Eighty-four percent of companies have a firm policy that employees leaving the company must surrender their mobile device(s).
Tracking software downloaded on devices and preventing software downloads came in third and fourth as the most challenging issues, respectively, but with the predicted growth of mobile malware, this number could change going forward.

Asset Tracking?
Nearly 60% believe that they are managing mobile security adequately, but nearly 75% surveyed felt that licensing and management of mobile device assets is a challenge; 52% track their assets using an automated tool, while 36% still use spreadsheets. Another 12% are not tracking mobile assets at all. Members of the Mobile Enterprise Editorial Advisory recently had few things to say about this topic.
The main software programs accessed through a mobile handheld device or smartphone are Microsoft (85%), Google (52%) and Adobe (26%). Many of these same software publishers aggressively protect their intellectual property through software audits.

BYOD
Fifty-one percent of organizations surveyed had a BYOD or BYOT [technology] program that allows employees to use their personal mobile devices for work purposes. Surprisingly, 60% who took advantage of a BYOD program only accounted for 25% or less of employees who brought in their personal devices. 
 
More than three-quarters (77%) allow their employees…
