Citrix NetScaler Delivers Massive Network Consolidation for Private and Public Clouds

Citrix Systems today unveiled four new additions to its leading Citrix NetScaler MPX and SDX product lines, delivering the unprecedented performance and virtualization that businesses require in the Cloud Era. Virtualization has been integral to the development of enterprise private clouds, which are being pressed to deliver unprecedented levels of utilization and elasticity. While server and storage infrastructures have been prime beneficiaries of virtualization, the end-to-end networking fabric - representing nearly one-fifth of total datacenter investment - has not yet included the virtualization of key networking services. What is required is a next-generation networking platform that integrates virtualization directly into the networking fabric to consolidate network services at scale, and deliver Pay-As-You-Grow elasticity. The new NetScaler SDX and MPX platforms, including the 50 Gbps SDX 21550 appliance, provide the right networking footprint to tackle large-scale network consolidation initiatives with the flexibility to scale without additional hardware.   

Successful network consolidation requires more than applying off-the-shelf virtualization to decouple selected networking functions from dedicated hardware. It demands a natively virtualized architecture that efficiently scales services, protects application SLAs by fully isolating processing resources, and delivers on-demand elasticity. The new NetScaler SDX platforms meet these requirements and more, supporting up to 40 completely independent NetScaler instances on a single appliance – 2.5 times more than competing hardware chassis-based solutions.

In addition, NetScaler SDX completely isolates system resources, such as memory, CPU and SSL processing, so that the demands of one application do not degrade the performance of another. Besides delivering dedicated SSL resources for each NetScaler service in a multi-tenant environment, the new platform also sets a new high-water mark for SSL performance.

Organizations are transitioning to 2048-bit SSL standards for stronger application security. This shift, along with increased SSL coverage across applications, is putting network and application performance at risk due to the increased processing demands required by stronger SSL key lengths. Smoothly transitioning to stronger 2048-bit SSL necessitates a re-examination of the infrastructure to ensure that processing capacity meets emerging needs. New NetScaler MPX and SDX platforms are designed from the ground up to handle 2048-bit and stronger SSL security, with support for 90,000 new 2048-bit SSL transactions per second, more than two times faster than the leading competitor.

What’s New

  • Industry-leading Network Consolidation: The new NetScaler SDX appliances integrate virtualization directly into the network fabric to support up to 40 completely independent NetScaler instances for large-scale consolidation projects. Each NetScaler instance and policy is supported by dedicated CPU, memory, SSL and compression resources to protect application SLAs, and to meet strict security and compliance mandates.
  • Fastest 2048-bit SSL Performance: NetScaler handles 90,000 new SSL transactions per second with 2048-bit keys, more than two times faster than the leading competitor.

Pricing and Availability

Citrix NetScaler MPX and SDX versions of the 17550, 19550, 20550 and 21550 appliances meet a broad range of price-performance requirements. These models are available later this quarter through Citrix Solution Advisors worldwide. Pricing begins at $145,000 for NetScaler MPX and $220,000 for NetScaler SDX - with no additional cost for enabling maximum SSL performance. Customers can upgrade platform performance and scalability with NetScaler Pay-As-You-Grow licenses.
