Appliance functions • Fibre Channel-IP conversion • Replication • Data reduction and compression • Monitoring and management Local site Remote site Journal volume 8. Consistent data is distributed to the remote volumes
Components and Topology Application servers • Application servers • Accesses data that needs to be replicated • Heterogeneous storage • Source or target for replicated data • RecoverPoint appliance (RPA) • Connects to LAN and Fibre Channel (FC)/WAN for replication management and replicating data over FC/IP • Connects to Layer 2 FC SAN for storage access • RecoverPoint appliance cluster • A group of inter-linked RPAs, working together closely, to provide replication services • RPAs in a RecoverPoint cluster are called nodes • WAN bandwidth management • Reduce WAN bandwidth by up to 90% through deduplication, compression, and write-folding RecoverPoint appliances FibreChannel/WAN Layer 2 Fibre Channel SAN EMC IBM HDS LSI HP Heterogeneous storage
RecoverPoint Family Details • RecoverPoint/CL • Supports EMC and non-EMC storage environments • Heterogeneous storage array support • Multiple arrays per site, EMC and non-EMC • Supports up to 300 TB of production data RecoverPoint/EX EMC storage environments Multiple EMC arrays per site Array-based splitting only Supports up to 300 TB of production data RecoverPoint/SE Supports VNX and CLARiiON environments Single VNX, CLARiiON, or Celerra unified array per site Supports Microsoft Windows host-based and VNX, CLARiiON array-based splitting only Supports 300 TB of production data Common functionality • One solution for data protection, replication, and disaster recovery • Local replication for LUNs in one SAN • Remote replication between LUNs in two SANs • Concurrent local and remote data protection that combines local and remote replication • Heterogeneous operating system support • Disaster recovery for VNX series file systems • Wizards automate production rebuild/restart • DVR-like recovery and consolidation reduces RPO and RTO • Application integration for Microsoft Exchange and SQL, other applications and databases • Integrated consistency groups support federated servers and storage • Synchronous or asynchronous local and/or remote replication with optional dynamic selection policies
Microsoft Failover Cluster A high-availability restart solution Node or resource failure automatically restarts failed nodes on another node where resources are available Node fails Resource Group: Microsoft SQL Resource Group: Microsoft Exchange Resource Group: Oracle Microsoft failover cluster provides high availability; shared-nothing cluster model
RecoverPoint/Cluster Enabler for Microsoft Failover Cluster LAN/WAN Private Interconnect Site A Site B File Share Witness with RecoverPoint/CE installed RecoverPoint Cluster nodes with RecoverPoint/CE installed Failover cluster supports 16 nodes with Windows Server 2003/2008 using Majority Node Set with and without File Share Witness
RP/CE & Hyper-V Overview Cluster Enabler 4 supports Hyper-V with failover clusters • Failover of the virtual machine (VM) resource • RecoverPoint/CE is deployed in the Hyper-V parent partition • Cluster relocation is at the VM level • Hyper-V Live Migration and Quick Migration—between nodes at the same or different sites • Live Migration supported with RecoverPoint CRR/CLR synchronous replication • Quick Migration supported with synchronous and asynchronous replication • Use for planned maintenance, such as VM relocation for hardware upgrades and software upgrades • Use for VM workload redistribution—move VMs between physical hosts
Target 2 Target 1 Prod 1 Prod 2 Disaster Recovery for Hyper-V Automated failover operations for Hyper-V environments LAN/WAN Private Interconnect Site A Site B Majority Node Set with File Share Witness RecoverPoint Cluster nodes with RecoverPoint/CE installed Hyper-V with Failover Clusters supports 16 nodes with Windows 2008 R2
R2 R2 R1 R1 Hyper-V Live Migration Planned hardware maintenance on physical server requires moving virtual machine(s)to another physical server Site A Site B Majority Node Set with File Share Witness RecoverPoint CRR synchronous replication
RP/CE 4.1.2 (new release) • Supported with RP 3.4.2 code • Supports RecoverPoint CLR topology • Failover is still limited to CRR copy (can’t failover to CDP) • New CE Group Policy “Auto Failover” • Provides missing flexibility which was absence in previous “Restricted group” (see next table) • No need to perform “RecoverPoint manual failover” on specific use cases • Supports Windows Server and Server Core for Windows Server 2008 • Up to 8 nodes per site with Windows Server 2003 • Up to 16 nodes per site with Windows Server 2008 and Windows Server 2008 R2 • Up to 16 child partitions with Hyper-V
Using RecoverPoint/Cluster Enabler • Supports Windows 2003 Cluster Services • Supports Windows 2008 Failover Clusters • Supported with Hyper-V • Repurposing does not work • MSCS failover enforces that remote cluster nodes can’t be manipulated • All resources of those nodes are not available outside of nodes • No access, mounting, multi-masking of LUNS to non-clustered hosts • Cluster Enabler 4.1 supports CSV • Requires Windows Server 2008 R2 SP1 • Support Majority Node Set, other quorum modes not supported • Only supports CRR • Toleration of CLR will be added 2H’2011 (addresses repurposing issue)
Supported Hyper-V configurations • Clustered HyperV (each VM reside on its own replicated Cluster Disks) • ClusteredHyperV with CSV volume (multiple VMs reside on single replicated CSV volume) • Standalone HyperV host (since CSV is only supported in Cluster, then each VM reside on its own replicated volume)
DEMO #1: SQL VDI Backup/Restore using Kutils 1) Backup using RP Hot Backup command the entire production database 2) Select RecoverPoint Hot Backup bookmark 3) Mount this Bookmark 4) Restore entire database on DR SQL Server
DEMO #2: SQL VSS Backup/Restore using KVSS 1) Perform SQL VSS bookmark using KVSS utility on production Host 2) VSS bookmark created successfully 3) Mount this Bookmark
4) Online replica volumes 5) Remove Hidden/Read-Only disk attributes 6) Assign drive letters 7) Attach SQL database using SQL Mgmt. Studio
Dynamic Business Intelligence and DR with SQL Server 2012 AlwaysOn and EMC RecoverPoint • Local high availability is provided by SQL Server “Denali 2010” AlwaysOn Availability Groups • Local data accessibility for destructive data access to enable Dynamic BI is enabled by RecoverPoint • Remote site crash-consistent database copies are available over extended distances with WAN optimization and no SQL Server overhead with RecoverPoint • Dynamic Business Intelligence is enabled, whereby rapid copies of large OLTP production databases must be available to business intelligence teams; • Within minutes • Must have BI SQL Server Instances fully isolated from production environments and networks • Supports dynamic BI where databases copies need to be writeable to support dynamic BI lookup scenarios • Continue to ensure the production databases copies are intact
SQL Server AlwaysOn and EMC RecoverPoint - The Best of Both Worlds-
