Maximizing Virtualized Storage to Drive Superior Performance

ATTO products are designed to excel in virtualized storage environments due to their advanced engineering and focus on performance optimization. These products typically feature high-bandwidth capabilities and low-latency connectivity which are critical in virtualized settings where data must be rapidly accessible across multiple virtual machines.

Our XstreamCORE bridges, built on the xCORE acceleration engine, as well as ATTO host bus adapters, network interface cards, and storage controllers use sophisticated data handling techniques such as advanced data streaming, which minimizes the impact of latency and maximizes throughput. This ensures efficient data transfers and reliable performance even under the high I/O demands typical in these environments. Additionally, ATTO products come with extensive support for multipathing, which enhances data accessibility and resilience, a crucial advantage in virtualized storage where data availability and system stability are paramount. Find out more about what makes our products different.

This combination of high performance, reliability, and support for advanced storage management features makes ATTO products particularly well-suited for virtualized storage infrastructures

Find out more about how ATTO is helping to changing what’s possible in the backup & archive application space.

Improved TCO

Time is money. Latency is Time. Looking to reduce costs while maintaining operation excellence? ATTO connectivity products combine cuts your latency along with energy efficiency and manageability to reduce costs while improving performance.

Eliminate Downtime

Avoid data loss in the event of a disaster by building out high-availability architectures with ATTO products. ATTO’s XstreamCORE® intelligent Bridges and HBAs and NICs enable new architectures that blend the elements of redundancy and performance for storage and network solutions.

Streamlining Datacenter Storage Disaggregation

Our products, especially XstreamCORE bridges with xCORE and eCORE acceleration capabilities, facilitate storage disaggregation by enabling more flexible, scalable, and efficient storage architectures. Their range of high-performance connectivity solutions, including Fibre Channel and Ethernet adapters, bridge the gap between computing resources and storage systems, allowing organizations to separate storage hardware from the compute nodes.

This separation is key to disaggregation, as it allows for storage resources to be pooled and managed independently from compute resources. ATTO’s products support this model by providing reliable, high-speed connections that ensure seamless access to storage pools across distributed environments. Additionally, ATTO’s advanced data routing and management features ensure that data flows efficiently between disaggregated storage components, enhancing overall system performance and scalability.

This makes ATTO’s solutions ideal for enterprises looking to optimize their data center resources and reduce costs through storage disaggregation.
