Accelerate Splunk Data Collection and Monitoring Over the WAN with Silver Peak

Manage remote sites faster, more effectively with Splunk. By eliminating 95 percent of data from the WAN, single host Splunk deployments can collect more information from long-distance remote sites in less time. Remote indexers can be mounted without overwhelming the WAN or sacrificing performance. Splunk-to-Splunk transfers complete quicker and use less bandwidth. With Silver Peak, Splunk performs more consistently at every location.

Splunk collects machine data and provides monitoring and analysis features that turn data into valuable insights to improve business operations. While effective within a data center, Splunk data transfers are susceptible to the increased delay encountered when operating across locations. 

As delay increases, TCP session throughput decreases and when distances become extensive, Splunk takes noticeably longer to retrieve and move information.  Even with nominal distances between locations delay may be a problem due to the routing policies and peering practices of the service provider networks connecting the offices. The fact that delay on a given route varies moment-by-moment, complicates root cause analysis.

Silver Peak addresses those underlying network problems, dramatically improving Splunk performance over distance. As much as  95 percent of Splunk data never has to be moved between locations, saving bandwidth and allowing critical Splunk operations to complete faster. Specifically, Silver Peak solves the following factors impacting Splunk performance over distance:

  • Bandwidth – Silver Peak byte-level deduplication  and compression can eliminate as much as 95 percent of the redundant data sent by Splunk across the WAN. The first time Splunk sends data it is fingerprinted and compressed by Silver Peak. Subsequent requests are fulfilled by the local Silver Peak instance.  
  • Latency – Silver Peak mitigates latency , enabling Splunk to operate more efficiently over distance. TCP Acceleration includes windows scaling, selective acknowledgements, and HighSpeed TCP. Accessing data stores or transferring files with Common Internet File System (CIFS) / Server Message Block (SMB) protocol is made more efficient with  CIFS Acceleration, which includes CIFS read-ahead, CIFS write-behind, and CIFS metadata optimizations. Latency is also reduced through packet coalescing, which re-packages multiple smaller packets into a single larger one, and through Dynamic Path Control, which selects the fastest path to a remote location.
  • Congestion – Silver Peak makes Splunk performance  more predictable across congested WANs regardless of whether Splunk runs over TCP or UDP. Lost packets are reconstituted in real-time, avoiding delays that come with multiple round-trip retransmissions. Retransmission and processing delays are further reduced by resequencing  out-of-order packets.

Silver Peak protects data in-flight between locations with an Accelerated IPSec virtual private network (VPN) running AES-256, the enterprise standard for data encryption. Data-at-rest is also encrypted with AES. End-to-end encryption is provided by SSL/TLS.

Silver Peak offers the most scalable and cost-effective data acceleration software for connecting data centers, remote offices and the cloud. You can download and deploy it  as a free, self-service trial in just 20 minutes or contact us to see how Silver Peak can help your organization.

  • Networks have never been more critical to the success of IT and the business. New virtualization and Cloud technologies and services are remaking the face of IT and the way in which infrastructure is architected. But the common thread throughout is the network, which must be both highly available and high performing. The tools, technologies, and practices of network monitoring and management address these needs, and are thus essential to the success of every enterprise and governmental organization.This Enterprise Management Associates (EMA) research report takes a detailed look at the current state of networks and network management, and examines five major areas of change and evolution affecting network management, including Cloud and virtualization, Software Defined Networking (SDN), big data, the rise of log data and APIs as management data sources, and the ongoing convergence of network operations teams and tools.
