2012 Server - Microsoft iSCSI Software Target 3.3

The Microsoft iSCSI Software Target 3.3 provides storage (disks) over a TCP/IP network. It turns a computer running Windows Server into a storage device which provides shared block storage. You can use Microsoft iSCSI Software Target 3.3 to perform a variety of storage-related tasks, including the following:
  • Provide shared storage for Hyper-V to enable high availability and live migration
  • Consolidate storage for multiple application servers (i.e. Microsoft SQL Server or Hyper-V)
  • Provide shared storage for applications hosted on a Windows failover cluster
  • Enable diskless computers to boot remotely from a single operating system image using iSCSI
The Microsoft iSCSI Software Target 3.3 is an economical solution suited for a development or test environment and a small, medium, or branch office production environment. It enables storage consolidation and sharing on a Windows Server by implementing the iSCSI (Internet Small Computer Systems Interface) protocol, which supports SCSI-block access to a storage device over a TCP/IP network. For details on how to manage iSCSI targets, see http://technet.microsoft.com/en-us/library/gg232606(WS.10).aspx

----------------
Microsoft ha messo a disposizione gratuitamente un target iSCSI, chiamato Microsoft iSCSI Software Target, al momento disponibile nella versione 3.3.

Di iSCSI si parla quando parliamo della Live Migration di macchine virtuali su Hyper-V sfruttando un volume CSV (Cluster Shared Volume). 

Microsoft iSCSI Software Target consente di esporre i dischi collegati ad un server come LUN accessibili via rete tramite appunto il protocollo iSCSI.

L’utilizzo insieme ad Hyper-V e in particolare l’attivazione dei Cluster Shared Volumes e l’utilizzo del MultiPath IO (MPIO) consente di abilitare scenari di alta disponibilità con Live Migration molto rapida delle macchine virtuali. Infatti, l’utilizzo di uno storage CSV su LUN iSCSI consente a tutti i nodi del cluster di vedere nello stesso momento il disco base della/e Virtual Machine, non rendendo necessario lo spostamento del disco da un host di virtualizzazione ad un altro.

News - The secret of productivity? Working for 52 minutes and then take a break of 17 minuti. - Il segreto della produttività? Lavorare per 52 minuti e poi fare una pausa di 17 minuti.

Il segreto della produttività? Lavorare per 52 minuti e poi fare una pausa di 17 minuti.E’ la ricetta proposta da DeskTime, società che monitora le prestazioni sul lavoro attraverso un software. Il test, che proverebbe il valore di questa formula, è stato condotto su una platea di utenti selezionati tra i più produttivi.
In sostanza, il lavoro più produttivo sarebbe una sorta di sprint sportivo che gli atleti-lavoratori affronterebbero, per fermarsi successivamente a riposare e poi ricominciare, pronti per una nuova performance. Non è molto utile, quindi, stare alla scrivania o al computer senza interruzioni per otto ore di seguito; meglio staccare spesso per recuperare e ripartire.
Il cervello degli uomini non sarebbe infatti tarato per un’attenzione costante per l’intero arco di otto ore consecutive, così come il corpo umano non è fatto per stare nella medesima posizione/postazione per tante ore di fila.

The secret of productivity? Working for 52 minutes and then take a break of 17 minuti.It's the recipe proposed by DeskTime, a company that monitors the performance on the job through a software. The test, which shows the value of this formula, was conducted on a selected number of users among the most productive.

In essence, the more productive work would be a sort of sprint athletes athletes-workers would face, then stop for a rest and then start again, ready for a new performance. It is not very useful, therefore, to be at your desk or computer without interruption for eight hours at a time; disconnect often better to recover and start over.

The brains of men would not have it calibrated for constant attention for the entire period of eight consecutive hours, as well as the human body is not made ​​to stand in the same position / location for so many hours in a row.
