Reading Time: < 1 minuteDo you need to understand SAN and NAS storage? There are several resources available online, but I would like to suggest a free course by Neil Anderson.

PowerStore datastore become unavailable in VMware vSphere

22 Gennaio 2022

Reading Time: 3 minutesDellEMC PowerStore is the new product line that will replace the old Equallogic/SC/VNX/Unity series. It’s a nice product with a mix of the features of all those prevuious products and a new modern design both in the hardware and the software parts. From VMware vSphere point of view it can be access as a block level storage with iSCSI and/or FC protocols, but it has also a native vVols implementation and, for example, in the PowerStoreX model it’s the default way to access at the storage resources.

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: 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).

iSCSI Extensions for RDMA (iSER)

7 Aprile 2020
Comments off

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.
