FLASH Symmetrix VMAX 40K Array with Enginuity 5876 Operating Environment • High-end enterprise storage array with simple, intelligent, modular design that allows system to grow seamlessly and cost-effectively from entry-level configuration to world’s largest storage array • New dense configuration options with 2.5” Flash, FC, SAS drives • Up to 33% more drives in the same footprint • More performance per Watt • Virtual provisioning provides non-disruptive, on-demand thin provisioning • FAST VP provides automatic storage tiering at the sub-LUN level • FAST VP SRDF coordination ensures performance at Recovery Site • FAST VP allocate by Policy • Cascaded storage groups • Simplified configuration and management with Unisphere for VMAX • Capacity efficient snapshot capabilities with TimeFinder VP SNAP • Federated Tiered storage FC SATA
4 TB 3 TB 3 TB Physicalallocation EMC Virtual Provisioning Overview • Improves storage utilization • Reduces storage provisioning complexity and overhead • Automates processes to easily grow storage • Overprovision storage to last lifetime of application, without providing all the physical storage up front • Add capacity non-disruptively and on demand • Automatically rebalance thin pools to maintain performance • Simplifies storage management with Unisphere for VMAX ESXi 1 10 TB ESXi 210 TB ESXi 310 TB Common Storage Pool
EMC Symmetrix FAST VP – Overview • Automatic storage tiering for Virtual Provisioning thin pools • Analysis and data movement at sub-LUN level: • Spreads data from a single thin device across multiple pools • Places very active parts of a LUN on high-performing Flash Drives • Places less active parts of a LUN on higher-capacity, more cost-effective FC or SATA drives • Moves data at the extent group level (7,680 KB) • Moves data based on user-defined policies and application performance needs • Data movement is automatic and nondisruptive Flash FC SATA • Radically simplifies storage management • Optimizes performance • Increases storage efficiency • Symmetrix VMAX with FAST VP – Getting the right data, to the right place, at the right time
FAST VP SRDF Coordination • FAST VP continually monitors and adjusts data placement at production site • Performance stats captured at both sites and exchanged every hour • Decisions on data placement made on both sites using data from the active site • Symmetrix VMAX with FAST VP and SRDF Co-Ordination– Getting the right data, to the right place, at the right time at both Production and DR Sites
Cascaded Storage Groups • New feature with 5876 providing the ability to nest multiple storage groups in a single masking view • Simplifies FAST VP configurations in virtual environments • Multiple application within a single masking view managed with its own storage group and FAST policy • Simplified monitoring and management at application level made easier
Solution Architecture • Two ESXi servers configured at each site • Oracle, SAP, and SQL Server deployed on VMs • EMC VMAX 40K storage arrays optimized by FAST VP protected by SRDF/S • 8 GBs FC SAN running between hosts and sites • 1 GB Ethernet network connection between hosts
Key Technology Components • EMC components: • Symmetrix VMAX 40K with Enginuity 5876 • Unisphere for VMAX • Symmetrix Remote Data Facility (SRDF) • Symmetrix FAST VP with SRDF coordination • PowerPath/VE • VMware vSphere 5 • VMware Storage Integrator(VSI) • Applications • Oracle Database 11g R2 Enterprise Edition • Microsoft SQL Server 2012 • SAP ERP 6.0 EHP 4
Virtual Pool Use by Application • SAP, Oracle, and MS SQL OLTP share common Flash, FC, and SATA pools • MS SQL DSS application shares a common SATA pool with all applications but is bound to a separate FC pool
Configuring FAST VP • FAST VP is either enabled or disabled • Data Movement should be set to automatic • Relocation Rate controls aggressiveness of FAST • New Feature Allocate- by-Policy simplifies capacity management of thin Provisioned environments Time windows Create time windows to specify when data can be collected for performance analysis and when data movements can be executed. Recommend to have windows always open so FAST VP can use most recent analysis to optimize data placement.
Enable FAST VP Coordination on Storage Groups • With this feature enabled, FAST VP sends device usage statistics from R1 to R2 to ensure that the FAST engine at the standby/failover site has up-to-date metrics on which to base decisions. • Enabled under storage group management in Unisphere: • Check Box: Enable FAST VP RDF Coordination • Coordination should be enabled on storage groups at both source and target VMAX
VMware Configuration • Reduce HBA queuing for vSphere ESXi servers by changing the queue depth • esxcli system module parameters set -p bfa_lun_queue_depth=64 -m bfa • Virtual Machine boot LUNs configured to use LSI SAS adapter • VMware Paravirtual SCSI (PVSCSI) adapters are used to configure DATA LUNs for high performance vCenterscreenshots
FAST VP Policies The table below details the FAST VP Policies set for our baseline configuration: • Both MSSQL1 and MSSQL2 applications share the same FAST policy • Policies restrict Flash tier to prevent any single application from dominating Flash resources
Validation and Testing Application Performance Validation Online Policy Tuning SRDF Coordination Application Failover with Rapid Ramp-Up
FAST VP Responsiveness and Flexibility • At 7:40am SQL OLTP policy adjusted to add additional Flash capability • After 30 minutes performance improvements were seen • SQL txn/sec increased and latency dropped • After 2 hours the SQL performance stabilized • Zero impact observed by other running applications
Validating FAST VP SRDF Coordination • SRDF coordination • Balance at Source and target • Similar tier usage at both sites • Solid lines are source devices • Dotted lines are target devices
SRDF Coordination, continued Source Array • Device has been balanced across all tiers in a similar distribution on both R1 and R2 [root@solenabler1 ~]# symcfg list -tdev -range 426:426 -bound -detail -v -sid 541 Symmetrix ID: 000195700541 Enabled Capacity (Tracks) : 1826068704 Bound Capacity (Tracks) : 1048590 S Y M M E T R I X T H I N D E V I C E S ---------------------------------------------------------------------- Pool Pool Total Bound Flags Total Subs Allocated Written Sym Pool Name ESPT Tracks (%) Tracks (%) Tracks (%) ---- ------------ ----- ---------- ----- ---------- --- ---------- --- 0426 FC10K_RAID1 F..B 1048590 0 570996 54 1044492 100 FLASH_3RAID5 -.-- - - 352524 34 - - SATA_6RAID6 -.-- - - 120972 12 - - Total ---------- ----- ---------- --- ---------- --- Tracks 1048590 0 1045620 0 1044754 00 Disaster Recovery Array
Failover Test • Application loads were run for extended periods at R1 site and FAST VP balanced storage groups on both arrays • RDF links split to simulate failover • SAP and Oracle were brought up on remote ESXi Server • Performance was monitored before and after failover Oracle & SAP Running at R1 Oracle & SAP Failed over and running at R2
Failover Test, continued • Following failover performance at application levels were on par with production • Transactions per minute and response timesobserved were equal
Summary and Solution Benefits • VMAX 40K provides an ideal platform for virtualized critical database applications, running varied workloads. • Cascaded storage groups enable simplified management of ESX environments with FAST VP. • FAST VP is tunable and responsive. By adjusting FAST policies, performance can be tuned to meet changing business performance needs. Increased performance within 30 minutes with no negative impact to other running workloads. • End-to-end visibility with VMware Storage Integrator from EMC enables simplified management and identification of VMAX devices direct from vCenter • SRDF coordination with FAST VP ensures production level performance at the R2 site in FAST VP environment in the event of a failover when configurations are similar. This delivers the performance and cost benefits of FAST VP at both production and disaster recovery sites.
