Ten or so years ago, network administrators were approached with a new idea: a system based in this new “Voice over IP” (VoIP) protocol that would carry both data and voice on the same wire. While managers were very excited about this new technology because it would save them money on infrastructure (cabling), PBX operators were not amused and did not take kindly to their 66-style punch blocks being rendered obsolete. Network administrators were left to learn and integrate this technology and everything else that went around it, such as Quality of Service and security.

Organizations are ready to promote greater value with virtualization, however, data center complexity and costs are skyrocketing. Virtual machines have emerged as the new “atomic unit,” moving fluidly throughout the data center, promising reduced costs and increased flexibility. Hindered by decreasing budgets and accidental architectures of the past, IT managers are struggling to realize the […]

Small Computer System Interface (SCSI) hard drives have been the preferred method of hard drive storage for servers in enterprise networks for a long time. The Serial attached SCSI (SAS) standard is an electrical standard in which SCSI hard drives are chained together and identified by a SCSI ID. SCSI is an electrical standard which only allows […]

The Cisco Nexus 7000 data center switch is a switch that provides layer 3 capabilities in the Nexus data center product lineup using the Cisco NX-OS operating system.  The Nexus data center switch is the first Cisco switch to provide virtual device context (VDC) capabilities that allow the data center switch to be logically segmented […]

The Cisco Nexus 7000 data center switch provides layer 3 capabilities in the Nexus data center product lineup using the Cisco NX-OS operating system. The Nexus data center switch is the first Cisco switch to provide virtual device context (VDC) capabilities that allow the data center switch to be logically segmented into up to four different […]

The Cisco Nexus switches allow a very high level of bandwidth connectivity positioned as data center switches. The Nexus switches do not support the same features and flexibility as local area network (LAN) based switches, but provide the very high capacity and cost effectiveness needed in data center environments. Nexus switches run a new operating […]
