#DFD1 – How Cloudera build a successful OpenSource strategy

3 June 2015
3 comments
Reading Time: 6 minutes

Some weeks ago I was invited to as a delegate at the first edition of Data Field Day (#DFD1) event, scheduled in May 13–15, 2015 in California (Silicon Valley and San Francisco).

Data Field Day event purpose was to cover different topics from others Technical Field Day events: from big data to analytics to hyperscale architecture and cloud security, and all waves of innovations that are transforming the IT. A new format for some growing trends, including micro-services, mobile and the Internet-connected world.

As written in a previous post not all presentations where completely in topic: some where too much storage oriented. But for the first edition of #DFD1 this was acceptable. Cloudera was one of the cases where this issue was not present.

After an upgrade to VMware vSphere 5.5 on a Dell PowerEdge R710, I’ve got strange occasion issues, where the hosts got completly disconnected from vCenter (with the ESXi/ESX host’s status as Not Responding or Disconnected in vCenter Server) and there was no way to reconnect, also after restarting the management services.

Locking in the ESXi console those kind of errors where notable: Bootbank cannot be found at path ‘/bootbank’.

The only temporally solution was power-off the VMs and restart the host. But the issue can randomly came back.

Reading Time: 3 minutes

In previous posts (see ESXi – Partitions layout of system disk and ESXi – More on partitions) I’ve described how are handles the partitions table on the destination installation media of ESXi 5.x (both in the case of a hard disk or a SD/USB disk).

With the new ESXi 6.0 the partition tables is similar in the case of a 1 or 2 GB destination device (like a previous SD media), but has some changes in the case of larger devices.

Core partitions remain the same with standard size: continue reading…

#DFD1 More about data or storage?

Reading Time: 5 minutes

Some days ago I was invited to as a delegate at the first edition of Data Field Day (#DFD1) event, scheduled in May 13–15, 2015 in California (Silicon Valley and San Francisco).

Data Field Day event purpose was to cover different topics from others Technical Field Day events: from big data to analytics to hyperscale architecture and cloud security, and all waves of innovations that are transforming the IT. A new format for some growing trends, including micro-services, mobile and the Internet-connected world.

But if you have seens some of the presentation video you may have some doubts if it was more a data (at high level) related event or a storage event (for some aspects it was also a Storage Field Day extra #SFDx).

Reading Time: 2 minutes

VMware EVO:RAIL represent the first Hyper-Converged Infrastructure offerings from VMware, announced in VMworld 2014 and available from the second half of 2014, and based (on the software part) on vSphere 5.5 and VSAN 1.0.

Now there is a new software release of VMware EVO:RAIL which includes also support for the VMware EVO:RAIL vSphere Loyalty Program.

One of the most notable improvements is that the scale of the hyper-converged infrastructure appliances are now doubled: from beyond the initial four appliances in a cluster and 16 nodes overall to eight appliances in a cluster and 32 nodes overall. Appliances running the updated EVO:RAIL software will now support approximately 800 general purpose virtual machines or 2,000 virtual desktop virtual machines per cluster.

Reset the VMware SSO password in vSphere 6.0

Reading Time: 3 minutes

Due to the changes in the new vCenter Server 6.0 architecture, the SSO has now been incorporated in the new VMware Platform Services Controller “role”.

But the concepts of a global SSO accounts still exist and remain important to manage the infrastructure (and more important during installation and upgrade). If you forget the SSO admin password you can have some trouble. I’ve already wrote on how reset the VMware SSO password in the vSphere 5.1 and 5.5 versions and the procedure remain almost the same also in the 6.0 version.
