Reading Time: 7 minutesThe L1 Terminal Fault (aka Foreshadow) bug is another speculative execution side channel attack that affects Intel Core processors and Intel Xeon processors only. For VMware vSphere, there are some patches available as described in this document: VMSA-2018-0020. All patches have been released on August, 14th 2018.

Reading Time: 4 minutesThis is the year of the security threats originated by hardware level bugs. The year has begun with the Spectre and Metldown bug with several months of possible solutions, new BIOS, new patches… and new variants of those bugs (like Spectre V4 and V5). But we are far from the solution because other bugs came out. And more will come out… All the software used at the microprocessor level and all the optimizations will probably be a good vector for new attack patterns. As already written, we are still far from the solution.

Reading Time: 3 minutesIn the last Veeam Community Forums Digest newsletter there is an interesting note about possible performance issues in VMware vSphere backup based on hot-add transport mode. VMware has confirmed that the increased Hot Add times experienced by some Veeam customers who have installed Veeam Backup & Replication Update 3a and the reason is the latest Virtual Disk Development Kit (VDDK) 6.5 version used in U3a to support also vSphere 6.5 Update 2.

Reading Time: 3 minutesOne common way to backup the VMware vCenter Server Appliance (VCSA) is to manage as a common VM and use a backup solution to backup (and restore) the entire VM. But it’s approach does not always work, for example in the case of a database corruption the VM restore could be not working. Starting with vSphere 6.5 and the new VCSA 6.5 was possible to use also a native backup solution integrated with the vCenter Server Appliance Management Interface (VAMI). But it was a manual operation (some scripts are available to automate and schedule it).

Reading Time: 2 minutesVM Explorer is another backup (and replication) tool with native support for virtualized platforms (vSphere and Hyper-V) with a good success in the SMB segment. Initially was build by a Swiss company (Trilead), acquired later by HP(E) and recently acquired by Microfocus. Lot of changes in the name, but not in the substance and with a good development and release cycles. Now Microfocus has released a new VM Explorer release (v7.1) compatible with the latest version of VMware vSphere 6.7.

Reading Time: 3 minutes Virtual Instruments has announced a new partnership with SANBlaze Technologies, Inc., a pioneer in SAN Emulation and validation technologies and a leading provider of storage solutions for embedded systems.
