Reading Time: 5 minutesMeltdown and Spectre are critical vulnerabilities existing in several modern CPU: these hardware bugs allow programs to steal data which is currently processed on the computer. Meltdown and Spectre can affect personal computers, mobile devices, server and several cloud services. Actually, the only way to minimize those security risks is to patch your operating systems and the hypervisor level (if you are using virtual machines).
Reading Time: 6 minutesAfter few weeks of the recent Intel CPU security bug, not yet closed (considering that affect also the recent Skylake family), there are new threads on the CPU. Meltdown and Spectre are critical vulnerabilities existing in several modern CPU: these hardware bugs allow programs to steal data which is currently processed on the computer. Meltdown and Spectre can affect personal computers, mobile devices, server and several cloud services. Depending on the bug, the affected CPU are Intel processors (since 1995!), some AMD CPUs, and several ARM-based Samsung and Qualcomm system-on-chips used for mobile phones.
Reading Time: 3 minutesNow that the PSOD on vSphere 6.5 and 10 Gbps NICs issue is finally solved seems that vSphere 6.5 critical bugs are closed, but it’s not totally true. During an upgrade from a vSphere 6.0, I’ve found a really strange iSCSI storage issues where all the VMs on the iSCSI datastore were so slow to become un-usable. First I was thinking about drivers or firmware, in the hosts and in the NIC (1 Gbps) or the firmware on the storage.
Reading Time: 17 minutesThis is an article realized for StarWind blog and focused on the design and implementation of a stretched cluster. A stretched cluster, sometimes called metro-cluster, is a deployment model in which two or more host servers are part of the same logical cluster but are located in separate geographical locations, usually two sites. In order to be in the same cluster, the shared storage must be reachable in both sites. Stretched cluster, usually, are used and provided high availability (HA) and load balancing features and capabilities and build active-active sites.
Reading Time: 2 minutesAfter the release of VMware NSX-T v2.0 only three months ago, now VMware has released the new version: NSX-T v2.1, that will enable advanced networking and security across these emerging app architectures, just as it does for traditional 3-tier apps. More specifically, NSX-T 2.1 will serve as the networking and security platform for the recently announced VMware Pivotal Container Service (PKS), a Kubernetes solution jointly developed by VMware and Pivotal in collaboration with Google. NSX-T 2.1 will also introduce integration with the latest 2.0 release of Pivotal Cloud Foundry (PCF), serving as the networking and security engine behind PCF. In these environments, NSX-T will provide Layer […]
Reading Time: 2 minutesNAKIVO has just released the release of NAKIVO Backup & Replication: the new version 7.3 is now much friendly with enterprise-grade deduplication appliances such as EMC Data Domain, HP StoreOnce, NEC Hydrastor, Quantum DXi, and other similar appliances, when they are used as a backup target. There is a new special backup repository type with the special architecture optimized for working with deduplication devices. Thus, before backing up VM data to a deduplication appliance, you can choose to use this repository type, and your data will be backed up to the storage server at a great performance […]
Reading Time: 14 minutesThis is an article realized for StarWind blog and focused on the design and implementation of a ROBO infrastructure. See also the original post. Introduction The fabric of SAN (means Storage Area Network) with Fibre Channel solutions have always been a dedicated network, with dedicated components (like FC switches). But, starting with iSCSI and FCoE protocols, the storage fabric could now be shared with the traditional network infrastructure, because at least level 1 and 2 have a common Ethernet layer (for iSCSI also layer 3 and 4 are the same of TCP/IP networks).
