Increasing VMware VMFS Volume April 17, 2011gunnalagLeave a comment With vSphere-4, you have option to increase the VMFS Volume similar to the way you expand the disk using Snap Drive/DiskPart on Window servers. Here are the steps for doing this:1. Increase the LUN (and Volume if applicable) size to new size on Neap Side.2. Select a particular host that has access to this Shared VMFS Volume -> Configuration -> Storage -> Properties3. Verify that the „Device Capacity‟ and „Primary Partitions Capacity‟ shows the difference in size that‟s increased above.4. Choose „Increase‟ -> select the desired Volume to be expanded and ensure its showing that free space will be added to expand the disk.5. Perform Storage Refresh on other hosts in the Cluster to get the new disk size reflected (can use Get-VMHostStorage –Refresh cmdlet to do this task) These steps can only be done by directly connecting to any of the hosts in the cluster.

G Categories:VMware Software vs. hardware iSCSI for VMware ESX January 1, 2011gunnalagLeave a comment 1. Hardware iSCSI Features and Limitations Below are some items to consider if you are planning to use the iSCSI hardware intitiator.1. ESX Server host booting from iSCSI SAN is possible only with hardware iSCSI initiator2. Multipathing support for failover only, no load-balancing by using multiple QLA4010s3. Support for VMotion, VMware HA, and VMware DRS4. Support for RDMs5. No support for Microsoft Cluster Server6. No VMware Consolidated Backup over iSCSI 2. Software iSCSI Features and Limitations Below are some items to consider if you are planning to use the iSCSI software intitiator.1. No support for booting ESX Server from software iSCSI2. Software initiator supports only a single storage interface (vmhba40)3. Multipathing support for failover only, no load balancing by using multiple physical network adapters (NIC teaming)4. Support for VMotion, VMware HA, and VMware DRS5. Support for RDMs6. No support for Microsoft Cluster Server7. No VMware Consolidated Backup over iSCSI 3. Step to enable MultiPath failover for iSCSI storage If you plan to use NIC teaming to increase the availability of your network access to the iSCSI storage
8. array, you must turn off port security on the switch for the two ports on which the virtual IP address is shared. The purpose of this port security setting is to prevent spoofing of IP addresses. Thus many network administrators enable this setting. However, if you do not change it, the port security setting prevents failover of the virtual IP from one switch port to another and NIC teaming cannot fail over from one path to another. For most LAN switches, the port security is enabled on a port level and thus can be set on or off for each port. Categories:VMware iSCSI SAN Design Considerations January 1, 2011gunnalagLeave a comment1. A basic difference between iSCSI and Fibre Channel is that when an iSCSI path is overloaded, the TCP/IP protocol drops packets and requires them to be resent. Fibre Channel communications over a dedicated path are not at risk of being overloaded. When a network path carrying iSCSI storage traffic is oversubscribed, a bad situation quickly grows worse and performance further degrades as dropped packets must be resent.2. Another potential disadvantage with implementing software-initiator iSCSI (but not hardware- initiator iSCSI) is that standard 10/100 Ethernet interfaces do not have enough throughput for practical iSCSI work. Gigabit Ethernet interfaces are required, and those interfaces tend to consume large amounts of CPU time. One way of overcoming this demand for CPU resources is to use TOEs (TCP/IP offload engines).3. TCP/IP offload engines shift TCP packet processing tasks from the server CPU to specialized TCP processors on the network adapter or storage device. The QLA4050 hardware initiator, which is supported on ESX Server 3.0, uses a TOE.4. iSCSI does not work well over most shared wide area networks. one should consider iSCSI a local-area technology, not a wide-area technology, because of latency issues and security concerns.5. One should also segregate iSCSI traffic from general traffic. Layer 2 VLANs are a particularly good way to implement this segregation.6. Best practice is to have a dedicated LAN for iSCSI traffic and not share the network with other network traffic. It is also best practice not to oversubscribe the dedicated LAN.7. f Categories:VMware VMware HA December 31, 2010gunnalagLeave a comment HA stands for one of the critical enterprise cluster feature of VMware called “High Availability”. It can be configured on a VMware cluster to auto recover VM‟s from a ESX host failure.1. When you configure HA via vCenter Server on VMware cluster, it1. installs Automated Availability Manager (AAM) (VMware HA agent) on individual ESX host
9. 2. The HA agent (AAM) runs a heartbeat mechanism on each host in a cluster to signal that the host is running and is a part of the cluster.3.4.5. g126.96.36.199. gf Categories:VMware KickStart automated ESX install December 31, 2010gunnalagLeave a comment1. Extract the ESX media from the bootable ISO/DVD received from VMware2. Copy them to a network location and make them accessible3. Create the ks.cfg (kickstart configuration file) answer file with custom values to installation options. The main sections of the ks.cfg file are as below1. accepteula or vmaccepteula (required)2. autopart (required)3. clearpart (optional)4. dryrun (optional)5. install (required)6. keyboard (optional)7. serialnum or vmserialnum (optional)8. network (optional)9. paranoid (optional)10. part or partition (optional)11. rootpw (required)12. %include or include13. %pre (optional)14. %post (optional)15. %firstboot4. The previous version to 4.0 of ESX server used to support incomplete ks.cfg file by which it uses the defined values for settings in the ks.cfg and prompt user for configuring the rest. This is now changed from ESX[i] 4.0 where you should have all the responses specified in ks.cfg or don‟t have the ks.cfg at all. So ESXi only allows a zero-touch builds via ks.cfg.5.

Types of Virtualization:1. Server : Where you use Virtual machines to separate hardware from virtual operating systems, allowing you to run the multiple operating systems on a single machine, all at the same time.2. Storage: Removing physical mapping of storage and moving storage into logical objects, which can be easily managed3. Network: process of combining hardware and software network resources and network functionality into a single, software-based administrative entity, a virtual network. There two types of N/W Virtualizations1. Internal: Network functionality provided by software2. External: combining multiple network functions into one unit4. Application: Process of encapsulating applications to be able to run on another system without actually installing them, allowing applications to run without conflicts5. Desktop: consolidation of desktop computers into virtualized server systems6. d2. How server virtualization can help?….1. Consolidate data center servers, desktops,2. efficient h/W resources utilization,3. less energy and cooling,4. less IT staff to maintain and increased IT productivity5. respond faster to business needs by faster server deployments6.
