Reading Time: 2 minutesOpenIO was a startup founded 26 June 2015 by a team of 6 co-founders (Guillaume Delaporte, Jean-François Smigielski, Julien Kasarherou, Laurent Denel, Marie Ponseel, Romain Acciari), experts in mail and data infrastructures. The headquarter was located in Lille, France, and there was also an OpenIO office in San Francisco. But on 24 July 2020, OVHcloud acquired OpenIO for an undisclosed amount.

Reading Time: < 1 minuteIl VMUG, in collaborazione con VMware ed Intel, ha organizzato una serie di Webcast sul tema “Bring Distributed Architectures for the Digital Future to Your Organization”. In particolare sugli aspetti legati alla sicurezza delle reti, considerando anche l’attuale situazione legata al COVID-19 e di come abbia cambiato il modo di accedere alle reti e alle applicazioni aziendiali.

Reading Time: 2 minutesNVMe over Fabrics (NVMe-oF) is a perfect alternative to the tradition protocols (iSCSI, FC, iSER, SMB3, and NFS) used to access external enterprise storage. These protocols are good for SAS drives, but they are proven to be inefficient for NVMe flash devices because they are using legacy commands sets designed for generic drives. The new NVMe-oF use the same NVMe commands designed only for fast flash drivers.

Reading Time: 2 minutesThere is a big issue in vCenter Server, with sensitive information disclosure vulnerability in the VMware Directory Service (vmdir). Under certain conditions vmdir that ships with VMware vCenter Server, as part of an embedded or external Platform Services Controller (PSC), does not correctly implement access controls.

Reading Time: 7 minutesQNAP is one of the leaders in the Home/SMB NAS area, with a lot of products including also some Enteprise solutions. But the big advantage of this product is the flexibility to add “apps” and extend the functions of the NAS itself to not only store data, but also use them or provide vertical solutions (like for example video-surveillance).

Reading Time: < 1 minuteThis year is very active for NAKIVO: on January they announced the version of NAKIVO Backup & Replication v9.1, on February the NAKIVO Backup & Replication v9.2 and now it’s the turn of NAKIVO Backup & Replication v9.3. The newest version offers native protection of Oracle databases via RMAN.

Reading Time: 2 minutesiSCSI Extensions for RDMA (iSER) accelera e migliora le prestazione del protocollo iSCSI utilizzando la modalità RDMA (Remote DMA) supportata da alcune schede di rete.  iSER consente ai dati di bypassare i driver di rete generici, il livello socket, e di accedere direttamente nel buffer di memoria del server. Anche il tempo di risposta si riduce per garantire la qualità di servizio del NAS. Combinando iSCSI con RDMA (Remote Direct Memory Access), iSER offre miglioramenti impressionanti e una maggiore efficienza sia per ambienti fisici, sia per ambienti di virtualizzazione.
