3 Heterogenous Multi-Pathing for VMware ESX 3

4 Virtualization puts increased pressure on storage performance and availability Performance & Resiliency Storage Heterogeneity Visibility & Reporting RAID10, SRDF, Thin, SSD drive SAN aware load balancing key for high VM density Proactive failover of storage connectivity during disaster Flexibility to choose ANY cost effective storage Optimized handling of ANY tier of storage Visibility into storage characteristics needed Data center wide I/O bottlenecks critical to isolate I/O bottlenecks to storage arrays! Getting locked-in by single array vendor Lack visibility into performance bottlenecks! Device naming complicated in ESX! Am I using the right tier of Storage? 4

5 Veritas Dynamic Multi-Pathing (DMP) for VMware: Improved storage I/O performance and availability Any X86 Server Guest Guest Guest Guest MPP VMware ESX Hypervisor DMP ESX PSA Framework Improve performance SAN & workload aware load balancing Real-time I/O performance graphs Increase availability Proactive path failover Automated path recovery Improve storage visibility Enhanced device naming Extended attribute discovery & reporting Data center storage reporting via vcenter Utilize a single multi-pathing solution across physical and virtual with heterogeneous storage 5

6 VxDMP Components and Architecture vsphere / ESX Components Dynamic Multi-Pathing Core MPP components ASL / APM packages Management Interfaces vcenter integration for operations, visibility and reporting ESX Servers vcenter Server VxDMP plug-in in vsphere client LAN CLI Server for remote administration vcenter Functionality I/O policy management SAN VxDMP Remote CLI Path management (enable/disable) Performance graphs and tables Storage DMP deployment statistics 6

7 Exploiting ANY Storage: Modular Architecture to Optimize to Any Storage Any Storage Array Support Library (ASL) ASL Module for each Array (Ex: VMAX, NTAP) Discovers Array Mode Types (A/A, A/P, ALUA) Discover array specific attributes (Tier, RAID, Repl) VMware ESX Guest Guest Guest Guest Array Policy Module (APM) HW specific plug in to DMP Dynamically loadable module ASL2 Understands Array specific failover behavior Allows Non Disruptive Upgrades for Controllers ESX Hypervisor ASL1 DMP APM2 APM1 Allows DMP to support 50+ array families & array models Dynamic Multi-Pathing for VMware SYMANTEC VISION

8 Improve operational efficiency and reduce complexity by using a single multi-pathing solution Dynamic Multi-Pathing Enables Storage Flexibility on all Platforms Veritas Cluster Server Veritas Cluster Server Veritas Application HA Veritas Storage Foundation File System Volume Manger Guest MPP Guest Guest Guest VMware ESX DMP for VMware DMP DMP ESX PSA Framework Reduce operational costs using a single multi-pathing solution Leverage extensive array support Standardize on single multi-pathing across storage management stacks Seamless migration from native multi-pathing to Dynamic Multi-Pathing Choose storage based on price / performance needs, avoiding lock-in 8

9 Advanced Usability, Visibility & Management 9

10 Centralize operations by managing in vcenter Plugin provides Dynamic Multi-Pathing storage and performance visibility Enables active management and infrastructure insight 10

11 Respond quickly with active path management Perform active path and policy management inside vcenter Change load-balancing algorithm on the fly Enable / disable individual path components 11

12 Improve performance with insight into storage performance and I/O statistics Granular performance metrics Visibility at infrastructure component level Tabular or graphical I/O Statistics 12

13 Get deeper visibility into your storage and make better decisions Deep visibility of the storage for your VMware environment Easily identify storage load by array or LUN Correlate I/O load from individual virtual machines 13

14 Bridging the Storage & System Information Gap Mapping OS Devices to SAN Devices Manageability naa c3d21800d8e0e88396d4e011 EMC0_19 EMC0_19 EMC0_0AF4 EMC0_0AF4 LUN LUN LUN WITHOUT DMP LSN: D600172E015B AVID: 0AF4 Challenges Native storage device names overly complex Native naming lack detailed array vendor or LUN information LSN sorting algorithm Consistent names across servers Intermediate for arrays that lack AVID naming Array Volume ID (AVID) naming Exposes LUN details to server admins Meaningful names for storage teams Dynamic Multi-Pathing for VMware SYMANTEC VISION

15 Improve visibility and bridge storage & server team information gap App Team Server Team Storage Team My application is on tier 1 servers, what tier of storage is it using? SSD, SATA, SAS, FC? My mission critical file system is being protected or not? RAID5, RAID10? Is my critical data being replicated underneath or not? Discover Device Characteristics from vendor list is replicated where raid level is 5 where LUN type is where Media type is Raid Levels RAID5, RAID10 Replication Attributes & Snapshots Thin Or Standard Devices Tier Information SSD, SATA, FC, SAS Enables AVID naming to make names meaningful for server and storage teams 15

16 Visibility DMP Remote CLI Interface Uncompromised visibility into VMware s storage infrastructure Enable / disable paths Select I/O balancing policies, on the fly Display DMP configuration (ASL/APM, tunables) Granular I/O statistics (enclosure, path, LUN, port) 16

17 Effective Load Balancing & Proactive Path Management 17

18 Optimize I/O throughput for greater performance Choose between seven I/O policies to achieve greatest performance for particular workload or storage array (for example): Minimum Queue (MinQ) I/O Policy Adaptive I/O Policy Adaptive-MinQ Balanced Round-Robin, Single-Active, Priority 18

19 Proactive Path Management: Smarter & Faster I/O Error Analysis Maximize Availability Regular IO ESX Hypervisor DMP inside ESX VMware PSA OS SCSI Drivers HBA Drivers Error Analysis Fast device discovery ASL s for optimized discovery APMs for handling ALUA, A/P & A/A arrays DMP Device Driver (VxDMP) Multi-threaded core processes Parallel handling of cascaded failures Automated & Reliable failback Leverage SCSI probes to test path status Load balancing of paths across controllers 19

20 Maximize Availability Improve data path availability Pro-active path management and failure detection Tunable monitoring to probe devices to ensure resiliency Automated path recovery after failure Added LUNs default to active I/O policy for enclosure Supports SAN boot devices Enables non-disruptive upgrade (NDU) of array firmware A B 20

21 Veritas Dynamic Multi-Pathing: Storage I/O performance and availability for your data center One solution for all OS, storage & architecture Enables multi-vendor environment & standardization Industry s broadest hardware compatibility list Utilize DMP to enable array and platform choice Enterprise grade performance Best in class throughput Proactive path management Utilize faster failover & effective load balancing Bridges storage & server boundaries Enables informed decision making Utilize vcenter & DMP for deep visibility Integrates with VMware vcenter Utilize vcenter for DMP administration Large financial automated all previously manual I/O tuning US Health provider achieved increased guest I/O visibility Dynamic Multi-Pathing for VMware SYMANTEC VISION
