1. The software provides infrastructure-wide storage virtualization functions that consolidate disk resources across incompatible devices without downtime. 2. It performs virtual disk pooling, auto-tiering of data to different performance tiers, thin provisioning to allocate just enough disk space, load balancing, caching, mirroring, and RAID functions. 3. The software centrally manages these resources from an intuitive interface and automates tasks like provisioning, monitoring, and failover to improve performance, utilization, and high availability.

Storage Virtualization Software Technical Feature Descriptions 1
Infrastructure-Wide Functions Across unlike & incompatible devices Without slowdowns or downtime Auto-Tiering
Intuitive, Self-Guided Workflow 3
Virtual Disk Pooling Consolidate like or unlike disk resources Split pool into tiers of different price/performance/capacity Create and assign virtual disks of desired sizes Define access rights Explicitly assign virtual disks to hosts or groups of hosts Expand capacity without downtime Eliminate stranded disk space 4
Remove Direct-Attached Drawbacks DAS Eliminate stranded storage W brand 6TB # P1 Make available capacity accessible to most needy applications Free W brand 8TB # G2 Choose disk characteristics based on program needs Defer additional purchase X brand until pool nears depletion 11TB # S3 Used 5
Manage Capacity as a Pool of Disk Space Tier Cost RAS Speed Density Disk Space (TBs) W brand W brand P1 model P3 model 1 Hi Hi Hi Lo 6TB Used W brand W brand G2 model G5 model 2 Med Hi Med Med 8TB Used SAN X brand Z brand S3 model Q7 model 3 Lo Med Lo Hi 11TB Used 6
SAN-wide Centralized Management Control / monitor all pooled resources from one console Intuitive to set up and operate Automates repetitive tasks Self-guided wizards for key workflows Comprehensive diagnostics & troubleshooting tips Configurable views of system behavior and performance Role-based, administrative permissions 7
Auto-Tiering Intelligent trade-offs between cost and performance No special disk hardware required You select which disks make up each tier Adapts to provide most demanding workloads with speediest response 8
Traditional: Virtual Disk Assigned to Tier Different pools satisfy different performance/capacity needs Best practice: Don't mix disks of different performance characteristics and/or sizes within one pool Tier 1 Fastest Performance Tier 2 Balanced performance/costs Tier 3 High capacity/Low Cost ERP Transactional workloads Databases File Email User home directory Archive Backup-to-disk Scratch files 9
Making Good Decisions on Your Behalf Monitor sustained I/O behavior across groups of disk blocks (chunks) Compare access frequency against average for each tier Promote or demote chunks to most suitable tier Tier 1 Tier 2 Tier 3 Chunks Above average Below average moves up a tier moves down a tier 11
Virtual Disk distribution within a pool Each Virtual Disk has a Storage Profile assigned Storage Profiles define tier preferences DISK POOL VD Tier 1 Tier 3 VD Storage Profile Storage Profile Tier 2 "High" "Low" VD Storage Profile "Normal" 12
Sensing Hot Spots within a Virtual Disk Heaviest hit blocks take advantage of Tier 1 performance Other blocks moved to Tier 2 & Tier 3 DISK POOL Frequently VIRTUAL DISK Accessed Tier 1 Tier 3 Moderately Accessed Infrequently Tier 2 Accessed 13
High-Speed Caching Speeds up performance Accelerates disk I/O response from existing storage Uses x86-64 CPUs and memory from DataCore nodes as powerful, inexpensive mega caches Anticipates next blocks to be read, and groups writes to avoid waiting on disks 14
Load Balancing Improve response and throughput Improve response and throughput Overcome typical storage- related bottlenecks Spread load on physical devices using different channels for different virtual disks Automatically bypasses failed or offline channels 15
Thin Provisioning Allocate just enough space, just-in-time Appears to computers as very large drives (e.g. 2 TB disks) Takes up only space actually being written to Dynamically allocates more disk space when required Reduces need to resize LUNs Reclaims zeroed out disk space 16
Guessing on Allocation Leads to Waste Disk 1 Disk 2 Disk 3 Free Few Blocks Actually Free Disk 1 Written To Free Disk 3 Free Free Disk 2 Disk 2 Capacity consumed whether used or not! 17

RAID Striping Better protection & performance Circumvents drive failures Spreads I/O across multiple spindles Offloads RAID 0 & 1 Supports popular RAID devices in pool 21
Synchronous Mirroring Real-time I/O replication for High-Availability Eliminates storage as a single point of failure Enhances survivability using physically separate nodes Updates two distributed copies simultaneously Mirrored virtual disks behave as one, multi-ported shared drive 22

Virtual Disk Migration Transparently move contents from one disk to another Allows non-disruptive hardware disk upgrades Clears & reclaims space occupied by original Provides pass-through access to drives previously used on other systems 28
Non-Disruptive Disk Upgrades Virtual disks remain active while contents are migrated to MPIO a different device Physical Storage Pool Old New Tier 1 Tier 2 Retain or discard Tier 3 older device 29
Online Snapshots Capture point-in-time images without tying up much disk space or make complete clones Recover quickly at disk speeds to known good state Eliminate back-up window Provide live environment for analysis, development & testing Save snapshots in lower tier, thin-provisioned disks without taking up space on premium storage devices 30
Low-impact, Point-in-time Snapshots Copy Empty when original contents Snapshot st write here on 1 enabled Active program If unchanged, read from Source 1 (Earlier point-in-time) 2 E p-i-t Source 3 Current image 4 Back-up Testing Analysis Recovery Only changed blocks Source disk take up space blocks 31
Continuous Data Protection & Recovery Return to any point-in-time without taking explicit backups Dial back to restore arbitrary point-in-time within a 48 hour time frame Logs and timestamps all I/Os to the selected virtual disks No need to quiesce or interrupt applications No host agents required Easy to turn on and revert from 32
Revert to Earlier Image Active CDP Time- Stamped Updates Cache Choose time before problem occurred 11:09am = 10:22am 9am 10am 11am 33
Remote Replication Update distant copies without impacting local performance Perfect for disaster recovery Only needs a basic IP connection to secondary site Bi-directional (sites can replicate to each other) Asynchronous Compressed, multi-stream transfers for fast performance & optimum use of bandwidth 34
Keep Remote Disaster Recovery Site Updated DR Site Recovery Destination Image Source Replicated Updates Cache Snapshot Queued Updates Active Cache Central IT site Asynchronous IP Copy 35
Advanced Site Recovery Expedite central site restoration Reverses direction of replication from the disaster recovery (DR) site to the primary datacenter Same automated process for virtual & physical systems 36
