Altro bug su CPU Intel: L1 Terminal Fault aka Foreshadow

Comments off

Reading Time: 5 minutesQuest’anno sarà ricordato, informaticamente parlando, come dei bug ai microprocessori. Si è iniziato subito ai primi di gennaio con gli annunci dei bug Spectre e Metldown ma poi si è continutato tutto l’anno. Prima per i goffi tentativi di sistemare i bug citati, ma poi anche per l’incombedere di nuove varianti dei bug. Si pensi che si è arrivati a Spectre V4 e V5! Ma è di pochi giorni l’annuncio di un nuovo bug. Di nuovo a livello hardware, di nuovo su processori presenti nel mercato da diversi anni, inclusi ultimi modelli (che ovviamente sono […]

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.

Gestire il backup della VCSA 6.7

12 Agosto 2018
Comments off

Reading Time: 4 minutesUno dei modi più utilizzati per gestire il backup della VMware vCenter Server Appliance (VCSA) era quello di usare una qualunque soluzione di backup a livello di VM. Soluzione semplice, ma non sempre efficace, visto che in caso di corruzione del filesystem o del database embedded, i risultati di un restore a livello di VM potrebbero essere disastrosi, lasciando una VCSA non funzionante. A partire da vSphere 6.5, la VCSA 6.5 ha aggiunto la possibilità di gestire un backup nativo, tramite l’interfaccia di gestione vCenter Server Appliance Management Interface (VAMI). Ma era comunque un’operazione manuale […]

Slow speed in network transport mode backup

7 Agosto 2018
Comments off

Reading Time: 3 minutesVMware vSphere provides a different way to copy the VM data during a backup operation: those modes are called transport modes. There are at least three major transport mode: network mode (or NBD), hot-add mode (or VM proxy mode), SAN mode (of storage offload mode). Most of the backup products can use those different transport modes depending on the configured infrastructure and the requirements.
