2. Module 2 - Components of vSphere


2.1.1. .

2.1.2. GOALS .

2.2. Virtualization Concepts

2.2.1. What is a VM -Virtual Hardware is really Software -Replace and upgrade hardware on the fly! - Add new devices without reboots -Real OS -Dedicated virtual hardware -Real applicaitons

2.2.2. What they do Snapshots Image Backups Add Virtual hardware on the fly

2.2.3. QUESTIONS 1 . Answer....

2.3. VMware Data Center Software

2.3.1. Your host: The hypervisor Resource traffic cop Provide virtual hardware to virtual machines Bare Metal and Hosted Hypervisor Bare metal - physical device installed as OS Hosted - VMWare Workstation vCenter IF you have a lot of ESXi hosts - manage them! Works for 1 or 100 Hosts Web host Multi Tier organization Lots of features vMotion DRS DPM Storage vMotion Storage DRS vSphere Data Protection HA FT vSphere Replication

2.4. VMware vSphere Cluster Features

2.4.1. vMotion Essentially copies Memory between ESXi hosts If anything goes wrong, original host stays in control Can migrate running virtual machines without shared storage!

2.4.2. DRS Monitors CPU and Memory usage on hosts. If unevenly burdened - end up with hot spot Maintain rules that match business objectives Binding or separating of machines (example redundacny)

2.4.3. DPM Leverages DRS to consolidate VMs onto fewer hosts during non peak times. Power on requires

2.4.4. Storage vMotion Want to perform maintenance - but dont want downtime Move storage location in real time Move from host to local!

2.4.5. Storage DRS Monitor storage habits of VMs - keep them more evenly loaded Load balance - for storage hosts Monitors I/O Keeps things performing as smooth as possible

2.4.6. Storage I/O Control VMs that suck up storage array - large database/email servers - consume lots of disk I/O Slows down VMs Typically share same storage devices - disproportionate share Control Busy Virual VMs .

2.4.7. vSphere Data Protection (VDP) Can accidentally delete files still Backup and Restore! Backup Restore vSphere Web Client . Leverages Data Duplication

2.4.8. High Availability (HA) Each ESXI host participates in communication Restarts VM on a different Host Each VM has a special set of software & drivers Should connection fail - due to OS crash or instability HA will restart VM for you! What about a particular application stays online? HA Can monitor services AND applications!

2.4.9. Fault Tolerance (FT) Runs real time mirrored copy Easy to configure Requires room on secondary host

2.4.10. vSphere Replication (VR) Copy VMs to a remote site in organization Branch offices can replicate VMs to host office! . .

2.4.11. QUIZ Questions... Answers...

2.5. Data Storage Concepts

2.5.1. Overview Storage Networking

2.5.2. Shared Storage Multiple computers access the same storage If it were stored locally - and host crashed, couldn't move to another host! REQUIRED FOR: DRS (Distributed Resource Scheduler) DPM (Distributed Power Management) Storage DRS HA (High Availability) FT (Fault Tolerance)

2.5.3. Storage Types: . .

2.5.4. VSA vSphere Storage Appliance Allows shared storage in ESXI Hosts Shared Virtual Storage! Designate disks within ESXI Hosts Intelligent replicated data between Hosts Benefits .

2.5.5. vFlash Leverage internal SSD in ESXI hosts to accelerate read times! Operates as Read Cache Need at least 1 SSD Drive in ESXI Host Configure VM Host to use SSD .

2.5.6. DataStores VMs don't know about underlying storage devices Believe they are using SCSI devices Everything is stored in CONTAINERS called Datastores. . VMFS vs NFS VMFS NFS

2.6. Network Concepts

2.6.1. Virtual Networking ESXI Hosts use iSCSI, NFS, FCoE (IP Storage) Also, managed by vCenter vMotion HA DRS VM Traffic

2.6.2. Address, virtual network card, virtual ethernet switches, virtual cables

2.6.3. Just make hardware into software! .

2.6.4. Physical switch is now Virtual... Use Virtual switches, or isolated networks for testing/development

2.6.5. Virtual Switch Types Standard Virtual Switch . Distributed Virtual Switch .

2.6.6. Virtual Networking Features VLANS Logical separation of network traffic. Often used to isolate different subnetworks such as test or restore network Traffic Shaping Feature that allows restriction of inbound and outbound network bandwidth of a group of VMs Help reduce congestion Port Mirroring Gives ability to monitor VMs traffic for troubleshooting or intrusion prevention Allows capture all traffic to or from VM QoS, DSCP Networking Standards for prioritization EX - Voice traffic from Call manager server Netflow pulls in Comm data CDP / LLDP Discovery protocols used to identify neighboring network switches QUIZ Questions

2.7. VMware Data Center Products

2.7.1. Overview .

2.7.2. Types .

2.7.3. Additional Products vCenter Operations Manager How do you know when you're having a problem? Get notified before problem Trend/risk monitoring! Efficiency issues Works with vCenter to gather SuperMetrics Dynamically adjusting thresholds vCenter Configuration Manager "nothing has changed...we didn't do anything"... Change discovery AND correlation View changes before - notifications with changes Tied into vCenter - review and monitor changes in vCenter, ESXI hosts, and VMs Compared configuration analysis vs 3rd party specs - automated Automatically fix performance issues! Great for Regulatory Compliance Security tool - systematic hardening and auditing! vCenter Site Recovery Manager Test disaster recovery Very hard to coordinate real restore Perform frequent non-disruptive plan. Anyone can initiate failover process Choose between certain or ALL VMs Replicate select VMs Multiple points in time as well REVIEW .
