Chapter 1 Introduction Chapter 1 Introduction Purpose of this guide This document provides detailed configuration steps and best practices for deploying Silver Peak replication acceleration software with EMC RecoverPoint for data protection across any network. This document builds on the VSPEX Proven Architecture for RecoverPoint, EMC document #H12298. Test and validation results are also included in Chapter 6. Business value EMC RecoverPoint is a data protection solution that provides local, and remote continuous data protection, allowing for any point-in-time data recovery. In the event of data loss, or corruption, data can be recovered across arrays and applications to a consistent state. This allows applications to be quickly restarted, resulting in shorter downtime. The VSPEX Private Cloud solution for VMware vsphere with EMC VNX and EMC RecoverPoint is a highly scalable, building block solution that has been validated for configurations up thousands of virtual machines. While EMC RecoverPoint provides an efficient replication solution, it is subject to limitations created by the Wide Area Network (WAN). When the WAN connecting the two replication units has latency, packet loss or out-of-order, or limited bandwidth, replication throughput can be adversely affected causing missed Recovery Point Objectives and potentially failed replication. Either of these expose the business to additional risk in the event or a recovery to the replica. Silver Peak develops data center class replication acceleration software that fixes the problems that exist on the WAN, enabling more data to be replicated, in less time, and over longer distances. Silver Peak s Virtual Acceleration Open Architecture (VXOA) can be deployed as virtual software (VX or VRX) on any hypervisor or as a hardware appliance (NX). VXOA solves WAN problems by deduplicating and compressing replication traffic, repairing dropped and outof-order packets, and overcoming the effects of latency. When combined with VSPEX for RecoverPoint, Silver Peak software enables customers to meet their RPOs regardless of WAN bandwidth, latency, or quality. 6

Chapter 1 Introduction Scope This guide is limited to the installation and configuration of the Silver Peak software, and changes that need to be made to a functioning RecoverPoint environment. This document does not cover the installation or initial configuration of RecoverPoint. For more information on deploying RecoverPoint please see the EMC VSPEX with EMC RecoverPoint for VMware vsphere 5.5 Design and Implementation Guide. Audience This document is intended for storage architects, IT engineers, storage administrators, professional services engineers, virtual administrators, and SAN administrators.

Chapter 2 Solution Architecture Overview Chapter 2 Solution Architecture Overview Solution Overview Silver Peak software is deployed as a virtual machine on the LAN. While Silver Peak software supports deployment across several hypervisors, this document focuses on VMware. When deployed with RecoverPoint, Silver Peak uses a single IP address and network connection to accelerate RecoverPoint replication, CRR. For this deployment no network changes need to be made, as all redirection will be performed by the RecoverPoint appliance. RecoverPoint RecoverPoint VNX 1 VMware vsphere VMware vsphere VNX Primary Data Center Secondary Data Center Figure 1. RecoverPoint and Silver Peak Solution Overview Silver Peak VXOA Overview Architecture Silver Peak provides a robust WAN optimization solution that addresses the bandwidth, latency, and packet loss issues that are common to most enterprise environments. Silver Peak's optimization techniques are all performed in real-time and primarily at the network (IP) layer to ensure maximum performance across the widest range of applications and WAN environments. 8

Figure 2. Silver Peak VXOA Architecture Chapter 2 Solution Architecture Overview Silver Peak appliances leverage the following Virtual Acceleration Open Architecture (VXOA) technology components to accelerate all enterprise applications in a secure and reliable fashion: Network Memory: Silver Peak's solution for disk-based WAN deduplication. Network Memory inspects all traffic that is sent between clients and servers, storing information as a local instance in Silver Peak appliances. Repetitive information is delivered locally rather than sent across the WAN, improving application performance and WAN utilization. Cross-flow payload and header compression provide additional gains on first-time data transfers and nonrepetitive traffic. Network Integrity: Silver Peak employs a variety of real-time techniques to address packet delivery issues common to shared WAN technologies such as MPLS and Internet connections. These include adaptive Forward Error Correction (FEC) and Packet Order Correction (POC) to overcome dropped and out-of-order packets, and advanced Quality of Service (QoS) techniques to prioritize traffic and guarantee network resources. Network Acceleration: Silver Peak mitigates the impacts of latency across the WAN by using various TCP acceleration techniques, like adjustable window sizing and selective acknowledgements. These tools help to overcome inherent chattiness that can otherwise hamper application performance across a WAN. Encryption: Silver Peak can encrypt network traffic using an AES-256 IPsec VPN. Any traffic sent between Silver Peak software instances can be accelerated and encrypted at wire speed. Virtual Deployment Options: Silver Peak can be deployed as a physical appliance (NX) or a virtual instance (VX/VRX). Silver Peak s virtual products can be deployed on any hypervisor (VMware, Microsoft Hyper-V, Xen, and KVM) and on any server hardware that meets the minimum requirements. Sizing VRX replication acceleration software is typically sized based on the available WAN bandwidth for data protection traffic, including replication, backup, and data migration. Each VRX model has a limit on the amount of WAN bandwidth that it will support. The VXOA software that powers VRX can also be limited in the amount of bandwidth that will be used on the WAN. For example, if you have 100 Mbps of WAN bandwidth, but only 40 Mbps is available for replication traffic, a VRX-4 will be used with a configured system rate limit of 40 Mbps. This allows the VRX-4 to take in as much data as possible, optimize the data, and then transmit up to the rate limit across the WAN. Table 2. Silver Peak Replication Accelerator Models Silver Peak Model VRX-2 VRX-4 VRX-6 VRX-8 WAN Throughput 20 Mbps 100 Mbps 300 Mbps 1 Gbps Average Accelerated Data Throughput 50 GBph 250 GBph 750 GBph 2 TBph 9

Chapter 2 Solution Architecture Overview Silver Peak also offers a full range of WAN optimization options that can be deployed as virtual or physical appliances. More information of Silver Peak s WAN optimization products is available at Silver-peak.com. Obtaining Silver Peak Software All of Silver Peak s software options are available on the Silver Peak marketplace with a 30 day free trial. When Should Silver Peak be Deployed with RecoverPoint Based on the testing and validation performed, we recommend that Silver Peak replication acceleration software be deployed with RecoverPoint in the following scenarios: The WAN has 40 ms or higher of latency, with packet loss of 0.1% or higher WAN latency is greater than 150 ms with less than 0.1% packet loss The WAN is shared with other data protection, or end user applications A vrpa is deployed on a server without sufficient resources to enable RecoverPoint deduplication and compression The RPA/vRPA consistently enters a high load state due to WAN problems, or high CPU utilization from deduplication and compression 10

Chapter 4 Installation and Configuration Silver Peak Best Practices Encryption Silver Peak can optionally encrypt all traffic sent between appliances using an AES 256 IPsec VPN. IPsec is configured on a per tunnel basis, allowing some sites to be IPsec-encrypted while others are not. To configure IPsec select the tunnel that is being used to send replication traffic by clicking on Configuration > Tunnels in the Silver Peak appliance manager. Click the name of the tunnel to open the Modify Tunnel screen. In the Modify Tunnel screen, select ipsec for the Mode, and enter an IPSec Preshare Key. The Key can be any text string, and must be the same on each end of the tunnel. Figure 14. Silver Peak Modify Tunnel Window Correcting Loss Forward Error Correction, FEC, is a tunnel option that is used to recover lost packets on the WAN in real time without requiring the data to be resent. Realtime packet loss can be measured in the Silver Peak appliance manager, Figure 14. Figure 15. Silver Peak WAN Loss % Chart When there is evidence of consistent packet loss on the WAN, a FEC setting of enable with a ratio of 1:5 is recommended. By using a FEC setting of enable 17

Chapter 4 Installation and Configuration with a ratio of 1:5, packet loss across the WAN will be corrected, increasing overall replication throughput. When packet loss is rare or intermittent, FEC should be set to auto with a ratio of 1:5. Auto will allow VXOA to dynamically control the amount of parity packets that are injected into the data stream, with the upper limit capped by the chosen Ratio value (1:5). For WANs that have zero packet loss, FEC can be set to auto or off. Off should only be used when there is no chance for bandwidth contention or dropped packets. When a setting of off is used, packet loss should be carefully monitored in the VXOA GUI. FEC is configured per tunnel, like IPsec. To configure FEC, open the Modify Tunnel window by clicking on Configuration > Tunnels in the Silver Peak appliance manager. Change FEC to enable or auto, and change Ratio depending on the amount of loss present. Table 3. Recommended FEC Settings WAN Loss FEC Setting FEC Ratio 0.1% or less Auto 1:10 Greater than 0.1% enable 1:5 RecoverPoint Configuration Add a New Default Gateway To redirect RecoverPoint replication traffic to the Silver Peak replication acceleration software we will be adding a static route, or gateway, to each RPA or vrpa that is replicating to the remote site. In a traditional deployment, the WAN router is the default gateway for all traffic leaving the local network. For this deployment the Silver Peak IP address, configured in the previous steps, will be used. By using the Silver Peak IP address, we can eliminate changes to the network router or switches.

Chapter 5 Validating Silver Peak Operation Chapter 5 Validating Silver Peak Operation To determine if the Silver Peak software is accelerating RecoverPoint, the Silver Peak element manager will be used to view RecoverPoint replication traffic. Measuring Performance with Silver Peak Silver Peak Performance Log in to the Silver Peak appliance manager and select Application View. For each RecoverPoint appliance that is sending replication traffic, there will be an entry that lists the IP address for the sending and receiving appliances, as well as the port numbers in use across the network. The status of the flow is also listed, and should be OPTIMIZED. The amount of data sent and received is listed as Outbound and Inbound, along with the reduction % that the Silver Peak software is able to achieve. Finally the Up Time for the flow is displayed, this value helps to determine how active the replication is and how long it has been sending data. Figure 21. Silver Peak Flow Performance Additional information is available for the amount of data that has been sent across the WAN by looking to the Outbound Data section of the Application View. Outbound data displays the top 5 applications that have been accelerated over the last 60 minutes, 24 hours, or 10 days. This data is useful to determine if something has changed in the environment and RecoverPoint is sending more or less data than is typically sent. Figure 22. Silver Peak Throughput Chart The Network View is also useful to determine the health of the WAN. The Network View displays the bandwidth usage across the WAN, The Top Applications accelerated, the minimum, average and peak latency and also the pre and post FEC loss. 20

Chapter 6 Testing and Validation Chapter 6 Testing and Validation This appendix details the testing and validation process that was used for Silver Peak and RecoverPoint. Silver Peak Testing and Validation with RecoverPoint Test Methodology A dedicated test environment was deployed to test deployment scenarios across several WAN configurations with varying latency and loss. Testing was performed with physical RecoverPoint Appliances (RPA) and virtual RecoverPoint Appliances (vrpa). For physical RPA testing, Silver Peak VRX-8 software running on VMware vsphere was used for acceleration Figure 2. While testing with the vrpa, Silver Peak VRX-4 software was used for acceleration. Using the VRX-4 allowed the vrpa and VRX-4 to run on the same VMware vsphere instance, providing a single server solution for data protection. Test Suite Overview The following components were used for RecoverPoint RPA and vrpa testing with Silver Peak. Table 4. Test Suite Details Device/Tool Name Version RecoverPoint SE RPA, vrpa 4.0.SP1 (k.137) Source Array VNX 5800 CLARiiON Splitter Target Array VNX 7600 Version 5.33.000.5.015 Silver Peak Appliances VRX-8, VRX-4 VXOA 6.2.0.0_46411 WAN Emulator KWANEM 52909 During testing, the following bandwidth, latency, and loss parameters were used. Table 5. Bandwidths Tested Bandwidth Tested Latencies Tested Loss Percent Tested RPA 1 Gbps 0, 20, 40, 60, 80, 120, 160, 200, 300 ms 0, 0.1, 1% vrpa 100 Mbps 0, 40, 80 120 ms 0, 0.1, 1% vrpa Test Results All vrpa testing was performed using a single server to host the vrpa and the VRX-4 software. Performance across latencies, with packet loss of 0.1% and 1%, is consistent when Silver Peak is used to accelerate the replication traffic. Without Silver Peak, RecoverPoint throughput is reduced by the combination 21

Chapter 6 Testing and Validation of packet loss and latency. Figure 24 shows replication throughput from the vrpa with 0.1% packet loss, while Figure 25 shows vrpa throughput with 1% packet loss. In both charts, Silver Peak helps RecoverPoint maintain a consistent throughput for replication, even with packet loss and latency.

Chapter 6 Testing and Validation RPA Test Results Physical RPA testing shows similar results to vrpa testing. RecoverPoint replication throughput is reduced on WAN connections that have latency and packet loss present. As latency increases, throughput decreases. With high levels of packet loss (1%), and high latency (greater than 80 ms), the RPA enters a high load state and is unable to maintain replication. Default configuration options were used for this testing, however tuning options are available to reduce high load states albeit at a reduced throughput. When Silver Peak software is deployed with RecoverPoint, replication throughput is maintained even when high levels of packet loss and latency are present on the WAN. Figure 27 shows replication throughput with 0.1% packet loss, typical of an MPLS network, with varying latency. Figure 28 shows replication throughput with 1% packet loss, typical of an Internet connection, with varying levels of latency.
