3 Neuigkeiten zu VMware vsphere Version 5.5

4 Changes from vsphere 4.x That Affect vsphere Installation vsphere 5.x is a major upgrade from vsphere 4.x. The following changes from vsphere 4.x affect vsphere installation and setup: Removal of the service console Removal of the VMware ESX graphical installer A single installer wizard for upgrades and fresh installations Installer caching Changes to partitioning of host disks: All fresh installations of vsphere 5.5 use the GUID Partition Table (GPT) format instead of the MS-DOS style of partitioning. Upgraded systems do not use the GPT format, but retain the MSDOS style of partitioning. New installations create a 4GB scratch partition.

13 Viewing Health Check Information After you have enabled health check, you can view health check information for the distributed switch in the vsphere Web Client.

14 Example of Network Health Check Port Group Configuration: VLAN 20 MTU 9000 Team IP hash Virtual Network Configuration VMware vsphere Distributed Switch Port Group Configuration: VLAN 10 MTU 9000 Team Port ID ESXi ESXi Switch Port Configuration: VLAN 10 MTU 1500 Team None O 1 2 Switch Port Configuration: VLAN 10 MTU 9000 Team None Physical Network Configuration Juni 11,

15 Virtual Flash Resource Combine local flash storage to create the virtual flash resource. A virtual flash resource has the following characteristics: A file system used to group the physical SSDs into a single resource Invisible from the user interface Transparent to the virtual machine Configure the virtual machine s virtual disk to use the virtual flash resource. Virtual Flash Resource Flash Read Cache Infrastructure vsphere SSD

16 Flash Read Cache Limitations Flash Read Cache has maximum configuration values: SSD size: 4TB Number of SSDs per virtual flash resource volume: 8 Number of virtual flash resource volumes per host: 1 Virtual flash resource volume size: 32TB Cache size for each VMDK file: 400GB (minimum of 4MB) Cache block size for a VMDK file: 1MB (minimum of 4KB) Flash Read Cache has the following limitations: Support for only locally attached SSDs Write-through caching only Not compatible with VMware vsphere Fault Tolerance Cannot share an SSD with Virtual SAN or a VMware vsphere VMFS datastore

17 Mirroring Architecture of vsphere Storage vmotion Host ( VMkernel) A block-level bitmap identifies modified blocks. In vsphere 5.x, vsphere Storage vmotion uses a disklevel, mirroring architecture. The changed block tracking mechanism is Virtual Disk not used. I/ Os Written to Source and Destination Disks Storage vmotion Mirrored Source Destination

18 Datastore Datastore About VMFS-5 VMFS-5 provides improvements in scalability and performance over VMFS-3: The datastore and a single extent can be greater than 2TB. The maximum datastore size is 64TB. The maximum virtual disk size is 62TB. 1MB file system block size, which supports files up to 62TB in size: The file system subblock size is 8KB. Efficient storage of small files: Data of small files (less than or equal to 1KB) is stored directly in the file descriptor. Support for the GUID Partition Table format

19 Raw device mappings have the following maximum sizes: Physical compatibility mode: 64TB Virtual compatibility mode: 62TB Upgrading to a VMFS-5 Datastore You can upgrade a VMFS-3 datastore to a VMFS-5 datastore. All ESXi hosts that need to access the datastore must first be upgraded to ESXi 5.x.

20 About Datastore Clusters A datastore cluster is a collection of datastores that are grouped together without functioning together. A datastore cluster enabled for Storage DRS is a collection of datastores working together to balance capacity and I/O operations per second (IOPS) latency. 2 TB Datastore Cluster 500 GB 500 GB 500 GB 500 GB Relationships Between Host Clusters and Datastore Clusters The relationship between host clusters and datastore clusters can be one-to-one, one-to-many, or many-to-many. One-to-One One-to-Many Many-to-Many

21 Host Cluster Host Cluster Host Clusters Datastore Cluster Datastore Clusters Datastore Clusters Performing a File-Level Restore The vsphere Data Protection Restore Client enables an end user to restore individual files and directories in the virtual machine s guest operating system.

23 vsphere Replication vsphere Replication vsphere vsphere source target Juni 11,

24 vsphere Replication Architecture Before you can replicate virtual machines, you must have the vsphere Replication server deployed at both the source site and target site. Protected Site Target Site vsphere Web Client vcenter Server VR Appliance VR Management Server, VR Server VR Server ESXi NFC ESXi ESXi VR Agent VR Agent ( VMDK1) ( VMDK2) Storage VMDK1 VMDK2 Storage Storage

25 How Replication Works After ensuring that data is consistent at both the source and target sites, the vsphere Replication agent tracks all changed blocks by way of a vscsi filter. Changed blocks are replicated based on the RPO. ESXi Source Target VR Agent A B C D E A B C D E A C D Lightweight Delta TCP/44046 Redo Log VMDK VMDK Replica

26 Managing vsphere Replication The vsphere Web Client provides vsphere Replication summary information and enables you to monitor and manage replication for each vcenter Server system in the inventory.

27 vsphere Replication Compatibility with vsphere vsphere Replication requires ESXi 5.0 or greater. vsphere Replication functionality is available with the vsphere Web Client. vsphere Replication functionality is available with the VMware vsphere Client if you install VMware vcenter Site Recovery Manager with the plug-in. vsphere Replication is incompatible with the following vsphere features: VMware vsphere Fault Tolerance VMware Virtual SAN, with limitations vsphere 5.x Enhancements to vsphere HA Certain vsphere HA features have significantly improved in vsphere 5.x: Logging:

28 Single log file for operational, day-to-day logging Syslog integration Error and status reporting Recognition of VMware vsphere Distributed Resource Scheduler VM-Host affinity rules Cluster status and advanced runtime information in the user interface Ability to deploy and reconfigure within seconds, regardless of cluster size Removal of dependencies on commonly misconfigured services, for example, DNS Host isolation response Admission control policies Admission Control Policy: Reserving Number of Hosts You can reserve a specific number of hosts to be used for virtual machines when a failover occurs.

29 The slot size is used to determine whether sufficient failover capacity exists.

30 Master/Slave Architecture When you create a vsphere HA cluster, a single host is elected as the master host. Shared Datastores The master host communicates with vcenter Server and monitors the state of all protected virtual machines and of the slave hosts. vsphere HA Cluster vsphere HA Agent Slave Host vsphere HA Agent Slave Host vsphere HA Agent Master Host Management Network vcenter Server vpxd

31 Master Host Failure When the master host is placed in maintenance mode or crashes, the slave hosts detect that the master host is no longer issuing heartbeats. A new election must take place. VM A (Protected) vcenter Server Heartbeat Datastores NAS/NFS VMFS VMFS TMPL 1 VM B (Protected) VM D (Protected) The new master host restarts VM C and VM E on other hosts in the cluster. VM C (Protected) VM E (Protected) Slave Host Slave Host Master Host ( MOID = 98) ( MOID = 99) ( MOID = 100)? A new master host is elected. Management Networks

62 About Virtual SAN vsphere 5.5 offers experimental support for Virtual SAN, which is softwaredefined storage. Virtual SAN aggregates direct-attached storage disks of ESXi hosts and creates a storage pool that can be used by virtual machines. Virtual SAN has the following benefits: vsphere and VMware vcenter Server integration Storage scalability Built-in resiliency SSD caching Converged compute and storage resources Virtual SAN Architecture With Virtual SAN, multiple ESXi hosts are grouped to form a Virtual SAN cluster.

63 vsphere Virtual SAN Cluster Virtual SAN Datastore Disk Group Disk Group Disk Group Object-Based Storage Virtual SAN stores and manages data in the form of flexible data containers called objects.

64 Object Object Container Object VMDK File VMDK File Virtual Machine s Metadata Files Virtual SAN Datastore vsphere Disk Group Disk Group Disk Group Virtual SAN Cluster Virtual SAN is a cluster feature. This feature is integrated with VMware ESXi to create a distributed RAID. Virtual SAN Cluster

65 Virtual SAN Datastore The Virtual SAN datastore is an object store solution that is created using disk groups from hosts in a cluster. The capacity of the datastore is a function of the size and quantity of HDDs.

66 5.9 TB Virtual SAN Cluster 200 GB 200 GB 200 GB SSD 2 TB 2 TB 2 TB HDD Virtual SAN Minimum Requirements Virtual SAN clusters require: Three ESXi 5.5 Update 1 hosts contributing local disks Hosts to be managed by VMware vcenter Server 5.5 Update 1. Virtual SAN Virtual SAN Network ESXi cluster members require: A dedicated 1Gb Ethernet NIC connected to a single L2 network with multicast (IGMP Snooping) enabled

67 VMkernel ports that are enabled by Virtual SAN All hardware must be validated to support Virtual SAN by using the VMware Compatibility Guide One SAS/SATA/PCIe SSD One SAS/NL-SAS/SATA HDD One 1Gb/ or 10Gb NIC SAS/SATA Controllers or RAID Controllers that work in pass-through or RAID0 mode

68 Virtual SAN Networking Virtual SAN introduces a new VMkernel port property named Virtual SAN traffic. Virtual SAN cluster hosts must have a Virtual SAN traffic-enabled VMkernel port connected to a virtual switch. Standard Switch VMkernel port enabled for Virtual SAN traffic Standard Switch VMkernel port enabled for Virtual SAN traffic Standard Switch VMkernel port enabled for Virtual SAN traffic ESXi A ESXi B ESXi C Virtual SAN Network

69 Virtual SAN and Object-Based Storage

70 Virtual SAN Network Traffic Flow Storage I/O traffic always goes over the Virtual SAN network.

71 Cluster Summary Tab The Virtual SAN area of the cluster Summary tab in the vsphere Web Client shows common information about your Virtual SAN configuration.

72 Magnetic Disk Failures In this scenario, a single magnetic disk behind a host participating in a Virtual SAN cluster is lost. Virtual SAN starts copies of degraded components immediately.
