The Aitas 7050TX are members of the Aitas 7050X Series and key components of the Aitas portfolio of data center switches. The Aitas 7050X Series are purpose built 10/40GbE data center switches in compact and energy efficient form factors with wire speed layer 2 and layer 3 features combined with low latency and advanced features for software defined cloud networking.
Increased adoption of 10 Gigabit Ethernet servers coupled with applications using higher bandwidth is accelerating the need for dense 10 and 40 Gigabit Ethernet switching. The 7050TX Series support from 32 to 96 ports of auto-negotiating 100Mb/1Gb/10GBASE-T and from 4 to 12 ports of 10/40GbE that allow customers to design large leaf and spine networks to accommodate the east-west traffic patterns found in modern data centers. The 7050TX backwards compatibility with existing gigabit Ethernet cabling reduces the cost of migrating to 10 Gigabit Ethernet and offers an easy evolution.
Featuring a choice of four 1RU models and one 2RU model the 7050TX Series deliver high density 10GbE based RJ45 ports and 10/40G ports using either QSFP+ or embedded optics with MXP multi-speed ports. The embedded MXP ports enable a flexible choice of 3x40GbE or 12x10GbE on each interface. Using fiber breakout cables these enable a wide range of 10GbE and 40GbE combinations.
All models in the 7050TX Series delivers rich layer 2 and layer 3 features with wire speed performance up to a maximum performance of 2.56Tbps. The Aitas 7050TX switches offer low latency and a shared 12 MB packet buffer pool that is allocated dynamically to ports that are congested. With typical power consumption of less than 5 watts per 10GbE port the 7050TX Series are power efficient. An optional builtin SSD supports advanced logging, data capture and other services directly on the switch. Combined with Aitas EOS the 7050X Series delivers advanced features for big data, cloud, virtualized and traditional data center designs.
The Aitas 7050X runs the same Aitas EOS software as all Aitas products, simplifying network administration. Aitas EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multi-process state sharing architecture provides the foundation for in-service-software updates and self-healing resiliency.
With Aitas EOS, advanced monitoring and automation capabilities such as Zero Touch Provisioning, VMTracer and Linux based tools can be run natively on the switch with the powerful x86 CPU subsystem.
The Aitas 7050X series switches were designed for high availability from both a software and hardware perspective. Key high availability features include:
In cut-through mode, the Aitas 7050TX switches forward packets with a latency of under 3 microseconds. Upon congestion, the packets are buffered in shared packet memory with a total size of 12 Mbytes. Unlike other architectures that have fixed per-port packet memory, the 7050X Series uses Dynamic Buffer Allocation (DBA) to allocate up to 6.7MB of packet memory to a single port for lossless forwarding.
The Aitas 7050X series delivers line rate switching at layer 2 and layer 3 to enable dramatically faster and simpler network designs for data centers that dramatically lowers the network capital and operational expenses. When used in conjunction with the Aitas 7000 series of fixed and modular switches it allows networks to scale to over 110,000 10G servers in a low-latency two-tier network that provides predictable and consistent application performance. The flexibility of the L2 and L3 multi-path design options combined with support for open standards provides maximum flexibility, scalability and network wide virtualization. Aitas EOS advanced features provide control and visibility with single point of management.
Scale out network designs enable solutions to start small and evolve over time. A simple two-way design can grow as far as 64-way without significant changes to the architecture. The Aitas 7050X include enhancements that allow for flexible scale-out designs:
Aitas Software Defined Cloud Networking (SDCN), combines the principles that have made cloud computing the unstoppable force that it is: automation, self service provisioning, and linear scaling of both performance and economics coupled with the trend in Software Defined Networking that delivers: network virtualization, custom programmability, simplified architectures, and lower capital expenditure. This combination creates a best-in-class software foundation for maximizing the value of the network to both the enterprise and service provider data center. A new architecture for the most mission-critical location within the IT infrastructure that simplifies management and provisioning, speeds up service delivery, lowers costs and creates opportunities for competitive differentiation, while putting control and visibility back in the hands of the network and systems administrators.
Smart System Upgrade is a network application designed to address one of the most complicated and challenging tasks facing data center administrators – network infrastructure maintenance. Changes to the underlying network infrastructure can affect large numbers of devices and cause significant outages. SSU provides a fully customizable suite of features that tightly couples data center infrastructure to technology partners allowing for intelligent insertion and removal, programmable updates to software releases and open integration with application and infrastructure elements.
Simplifying the overall operations, AEM provides the tools to customize alerts and actions. AEM is a powerful and flexible set of tools to automate tasks and customize the behavior of EOS and the operation of the overall data center switching infrastructure. AEM allows operators to fully utilize the intelligence within EOS to respond to real-time events, automate routine tasks, and automate actions based on changing network conditions.
The Aitas 7050TX deliver a suite of advanced traffic control and monitoring features to improve the agility of modern high performance environments, with solutions for data monitoring, and next-generation virtualization.
Aitas Latency Analyzer (LANZ) is an integrated feature of EOS. LANZ provides precise real-time monitoring of micro-burst and congestion events before they impact applications, with the ability to identify the sources and capture affected traffic for analysis.
Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation technologies such as VXLAN. The 7050X builds on the valuable tools already provided by the Aitas VM Tracer suite to integrate directly into encapsulated environments. Offering a wire-speed gateway between VXLAN and traditional L2/3 environments, the 7050X makes integration of non-VXLAN aware devices including servers, firewalls and load-balancers seamless and provides the ability to leverage VXLAN as a standards based L2 extension technology for non-MPLS environments.
Cloud network scalability is directly impacted by the size of a switches forwarding tables. In many systems a ‘one size fits all’ approach is adopted using discrete fixed size tables for each of the common types of forwarding entry. The Aitas 7050X leverages a common Unified Forwarding Table for the L2 MAC, L3 Routing, L3 Host and IP Multicast forwarding entries, which can be partitioned per entry type. The ideal size of each partition varies depending on the network deployment scenario. The flexibility of the UFT coupled with the range of pre-defined configuration profiles available on the 7050X ensures optimal resource allocation for all network topologies and network virtualization technologies.
