Silver Peak Extends Replication Performance Over WAN

Silver Peak Systems, Inc. announced that its WAN optimization software has been certified to accelerate remote replication for the new Dell Storage SC4000 Series arrays, also announced.

Silver Peak’s software-based approach to data acceleration overcomes WAN impediments like distance, poor quality and limited bandwidth helping storage and IT administrators to meet RPO while saving money on network infrastructure.

The new SC4000 Series arrays bring high-end storage capabilities to mid-sized deployments, offering all-flash performance for up to 72% lower costs than competing pure flash arrays. The enterprise arrays offer the same intelligent data placement capability as the Dell Compellent SC8000 that moves data among traditional rotating drives, write-optimized flash (SLC) and read-optimized flash (MLC) drives to optimize overall storage costs.

When Silver Peak software is combined with the SC4000 Remote Instant Replay, companies can protect up to 20x more data over existing networks. Silver Peak complements SC4000 by reducing TCO and enabling customers to deploy over existing, lower cost networks like Internet/VPN in collaboration with Dell storage.

“Deployed with our Dell SC-Series Storage SAN-to-SAN replication, Silver Peak is enabling us to replicate up to four times the TB of data per day,” said Steve Borba, AVP and network security manager, Citizens Business Bank. “Silver Peak improved our usable bandwidth by more than 22x, providing headroom for future growth.“

The SC4000 Series can scale to more than 400TB of raw capacity and can support a range of workloads. For example, it can host up to 10,000 Exchange 2013 user mailboxes in a single 2U SAN with 24 HDD drives or can achieve nearly 120,000 IO/s with less than one millisecond latency for OLTP or mixed workloads. With the addition of Silver Peak, remote replication throughput over the WAN can be increased to accommodate up to 2TB/hour of replication capacity without having to upgrade the existing infrastructure, which extends capacity for future growth (hourly data throughput based on an average of 6x data reduction over a 1Gb/s WAN.).

Silver Peak overcomes the common challenges that hamper offsite replication over shared WANs or the Internet, including limited bandwidth, distance and network quality. With Silver Peak’s simplified storage forwarding method, deployment takes less than 20 minutes and is done without complex network configuration changes. Administrators simply download and install Silver Peak software in the data center and DR sites, point the Dell Storage arrays to Silver Peak, and in minutes start accelerating replication traffic.

In joint Silver Peak and Dell lab testing, the combined solution delivers 6x to 20x better replication performance on average compared to un-optimized replication environments. For example, on a 155Mb/s shared network between Atlanta, GA and Dallas, TX (40 ms of latency), the time required to replicate a 20GB dataset was reduced from 1.3 hours to 3 minutes.

“Silver Peak continues to build on its status as a Dell global partner for WAN optimization by providing Dell Storage users performance over the WAN that is equivalent to a dedicated, low-latency link,” said Marc Trimuschat, VP alliances and the Dell relationship for Silver Peak. “By combining Silver Peak data acceleration software with the new Dell Storage SC4000 Series, enterprises can easily meet their RPOs, lower DR costs, and extend distances between replication sites using their existing WAN infrastructure.“

Silver Peak software for Dell storage is available with a free 30-day trial and supports the entire line of Dell storage solutions – including SC-series, PS-Series, and MD-series. Pricing for Silver Peak replication acceleration software starts at approximately $5,000 for a one-year subscription, which includes two Silver Peak software licenses and support. Perpetual pricing options are also available. To download a free 30-day trial.

Silver Peak is a Dell global partner for WAN optimization and storage replication in more than 30 countries. It provides real-time network optimization techniques within Dell data center switching, campus networking, server and storage products. Silver Peak is also with Dell data center and branch solutions, where Silver Peak software can run on PowerEdge servers, blades, or the new PowerEdge VRTX shared infrastructure platform.
