Virtual Machine Compute Optimizer Version 2.0.0

The Virtual Machine Compute Optimizer (VMCO) is a Powershell script that uses the PowerCLI module to capture information about the hosts and VMS running in your vSphere environment, and reports back on whether the VMs are configured optimally based on the Host CPU and memory. It will flag a VM as “YES” if it is optimized and “NO” if it is not. For non-optimized VMs, a recommendation is made that will keep the same number of vCPUs currently configured, with the optimal number of virtual cores and sockets. Note that the VMCO will not analyze whether your VMs are configured with the correct number of vCPUs based on the VM’s workload. A more in-depth analysis tool such as VMware vRealize Operations Manager can make right-sizing determinations based on workload and actual performance. Changes in Version 2.0.0 Priority of the findings are captured Details on the findings are included Cluster information is captured to determine if Host HW is not consistent across the cluster Report if a VM spanning pNUMA nodes actually has the pNUMA exposed to the guest OS Report if advanced settings have been changed on the VM or host level to expose pNUMA to the guest OS Reports...

What’s RAMBleed? Steal Sensitive Data From Computer Memory

RAMBleed is a side-channel attack that enables an attacker to read out physical memory belonging to other processes. The implications of violating arbitrary privilege boundaries are numerous, and vary in severity based on the other software running on the target machine. As an example, in our paper we demonstrate an attack against OpenSSH in which we use RAMBleed to leak a 2048 bit RSA key. However, RAMBleed can be used for reading other data as well.

[Update]: EMC VNX2 Storage Systems – Drive and OE Compatibility Matrix (Feb 2018)

EMC VNX2 Drive and OE Compatibility Matrix The document will help you to know that the minimum compatibility between VNX storage system OE and disk drives. The supported part numbers and minimum version of software are listed. Before installing a new disk in a storage system, use the EMC Unisphere Manager to determine the VNX OE revision running on the storage system. In Unisphere Manager, the VNX OE revision appears on the Software tab of the Storage System Properties dialog box for the storage system. Note 1: Changes and additions in the tables since the last revision of this document are noted in red type. Note 2: The disk part number (PN) appears on a label on the front of the disk carrier. Note that although the OE GUI may display an alpha suffix at the end of the PN (like PWR or SSD) these characters are not part of the actual orderable PN. Note 3: PNs in tables with a ‘YES’ entry in the Spin-Down Support column may report a suffix of PWR through the OE GUI (EX: 005049278PWR). This PWR suffix is used by the OE and is not part of the actual orderable PN. Supported Disk Drives...
