As a key part of the new vCloud Suite, vCloud Director 5.1 gets a bunch of new features, and takes on a new role. The new role is that vCD is built into the suite, and is the layer where the cross-cluster capabilities are implemented. Therefore vCD becomes much less of a Cloud Management solution, and much more of a key part of the platform which implements Virtual Data Centers (VDC’s) for customers.

Coming on the heels of VMware’s acquisition of Nicira, Oracle announced today that it is acquiring network virtualization vendor Xsigo Systems for an undisclosed amount.
Just what are storage hypervisors? There are several companies that claim to have storage hypervisors. Wikipedia states that a hypervisor is “conceptually one level higher than a supervisory program”. We also know that from our normal use of hypervisors that they manage the underlying resources that a guest uses. Do these definitions work for a storage hypervisor?
Storage Security is not only about Encryption, which is just one aspect of Storage Security requirements for the virtual and cloud environments. It is also about increasing defense in depth and knowledge of what is touching your storage environment. As well as providing security around those touch points and to a great extent auditing and protecting the data residing within the storage devices regardless of where the devices live: within the virtual environment or within a cloud.
I recently had the joys of helping deal with an All Paths Down (APD) situation which presented itself when removing a LUN from all the hosts in a cluster. If you do not detach the device first, which will also initiate an unmount operation before you physically unpresent the LUN from the ESX, it causes an APD situation to happen. ADP is when ESXi server no longer has any active paths to a device. When the device is no longer present and you rescan the adapters ESXi server will still retain the information on the removed devices and hostd will continue to try to open a connection to the disk device by issuing different commands like read capacity and read requests to validate the partitions tables are set. If SCSI Sense codes are not returned from a device (you are unable to contact the storage array, or the storage array that does not return the supported “SCSI codes”), then the device is in an All-Paths-Down (APD) state, and the ESXi host continues to send I/O requests until it times out.

EMC VSPEX is a converged infrastructure offering targeting private clouds offered through EMC and VMware VAR’s. This focus upon the channel makes this the first “private cloud in a box” that is explicitly designed for VAR’s and SI’s to take to their mid-market customers. As such the potential for such an offering is huge. However it is highly likely that the success of VSPEX will be clouded by EMC’s less than stellar track record with the channel, and the complete absence of management software from the offering.
