â€œConvergenceâ€ is a buzzword seen in the IT press constantly these days. All convergence means is placing communications that used to ride on its own network onto one unified network; Ethernetâ€™s cheapness, ubiquity, and ever-growing link speeds makes it the network everything is moving towards. The first big convergence move was to combine voice networks with data networks, using IP telephony. The challenges of a converged voice/data network include prioritizing voice traffic over pretty much anything else during times of link congestion, and keeping call quality high by delivering datagrams in a predictable time with a predictable gap in between those datagrams.

Windows Storage Server is one of the most interesting products from Redmond, a specialized version of Windows Server with integrated storage target capabilities, including iSCSI, NFS, SMB, and single-instance storage (file-level deduplication). Although Windows Server 2008, with its many storage feature updates, was released last year, the updated version of Windows Storage Server was still under construction until last month. But Windows Storage Server 2008 is available to manufacturers today.
I’ve just come back from a NetApp training course; good course and recommended for anyone who wants to pick up some storage fundamentals, it covers all the NetApp bases and by the end of it, you should be fairly confident to do pretty much all the day-to-day routine tasks that you might be asked to do as an administrator of a NetApp array.
We think of web apps as what belongs in the â€œcloudâ€. Virtualization is changing this so that both small and enterprise apps are a fit. To me there can be an internal cloud and an external cloud. As virtualization continues to evolve, we will see the lines blur between both.
Most physical to virtual migrations (P2V) of servers end up as virtual machines with the partitions encapsulated in virtual disk (.vmdk or .vhd) files. But what if the physical server already has a partition that’s configured through an iSCSI connection to the SAN, and what if that’s the same SAN that the new VM will […]
