Cisco Seen Building Momentum In Nexus 9K, ACI


Cisco is getting a lift from obvious driving force behind its Nexus 9000 switches and fabric Centric application infrastructure. Investment company UBS raised its price target after talks with Cisco EMEA boss Chris Dedicoat thrown UBS numbers found encouraging.

Cisco Nexus 900 1000 9,000 customers and 120 customers ACI and Policy Controller application infrastructure and business Q1, according to UBS analyst Amitabh Passi, based on his conversations with chronic Dedicoat here in Barron. Defined Passi sense of confidence and dynamism in control, software, data centers, mobility and ASR 9000 edge-routing networks.

There Could Be More To Come:

While respectable, we are still in the early days of ICA given ramp installed base of Cisco UCS and 37K + 50K + Cat-6k customers.Cisco expected to announce its Nexus 9000 1000th customer and client 100a APIC next week in the Cisco Global Editors Conference in San Jose.HP could be the tailings layer of Cisco switching pulse. According to the knowledge of the data center, HP has burst open their systems Cisco converged infrastructure to support top-of-rack switches.

Until recently, cloud systems HP ProCurve switches only supported. But the company is offering customers the option of Cisco based on the ubiquity of Cisco switches in global data centers.HP and Cisco have gone from being partners in fierce competitors in the last five or six years due to the inclusion of Cisco the server market data center with its Unified Computing System platform and building your HP networking portfolio through the acquisition of 3Com. HP went so far as to remove all your Cisco networking equipment from its own data centres.

The same seems dynamic partner / opponent suffers Cisco and EMC. Shortly after completion of its investment practically leave the VCE integrated infrastructure joint venture with EMC, Cisco has with IBM to provide an integrated platform that UCS infrastructure combined with storage system.The resulting system VersaStack IBM Storwize addresses the supply cloud, big data and Analytics and providing mobility. 

Over time VersaStack is for business applications from IBM and Cisco integrate ICA and InterCloud Tela be optimized. It channels are sold by both companies worldwide and Cisco and IBM said they will seek to introduce additional reference architectures Time. now that the participation of Cisco VCE was reduced to 10%, the EMC and VCE is not expected to Cisco embrace networking technologies integrated into their infrastructure.
