VCP-410

ESX/ESXi uses at least 50MB of system memory for the VMkernel. This is not configurable. It depends on the number and type of PCI devices. An ESXi host uses additional system memory for management agents. o The service console typically uses 272MB. o Memory activity is monitored to estimate the working set sizes for a default period of 60 seconds. o ESX/ESXi charges more for idle 220 701 memory than for memory that is in use. This is done to help prevent virtual machines from hoarding idle memory. o Hosts can reclaim memory from virtual machines using: o Memory balloon driver (vmmemctl) - collaborates with the server to reclaim pages that are considered least valuable by the guest operating system. Closely matches the behavior of a native system under similar memory constraints. Causes the guest to use its own native memory management algorithms. You must configure the guest operating system with sufficient swap space. o Swap Files - hosts use swapping to forcibly reclaim memory from a virtual machine when the vmmemctl driver is not available or is not responsive. You must reserve swap space for any unreserved virtual machine memory (the difference between the reservation and the configured memory size) on per-virtual machine swap files. o If you are overcommitting memory, to support the intra-guest swapping induced by ballooning, ensure that your guest operating systems also have sufficient swap space. This guest-level swap space must be greater than or equal to the difference between the virtual machine’s configured memory size and its Reservation. o Many workloads present opportunities for sharing memory across virtual machines. o To determine the effectiveness of memory sharing use resxtop or esxtop to observe the actual savings. The PSHARE field of the interactive mode in the Memory page. o You measure guest physical memory using the Memory Granted metric (for a virtual machine) or Memory Shared (for an ESX/ESXi host). To measure machine memory, however, 220 702 use Memory Consumed (for a virtual machine) or Memory Shared Common (for an ESX/ESXi host). o The VMkernel maps guest physical memory to machine memory. o Multiple regions of guest physical memory might be mapped to the same region of machine memory (in the case of memory sharing) or specific regions of guest physical memory might not be mapped to machine memory (when the VMkernel swaps out or balloons guest physical memory) o Resource Pool Hierarchy can have Parents, Children, and Siblings. o Resource Pool Admission Control - Before you power on a virtual machine or create a resource pool, check the CPU Unreserved and Memory Unreserved fields in the resource pool’s Resource Allocation tab to determine whether sufficient resources are available. o A group power on will power on multiple virtual machines at the same time. o VMotion does not support raw disks or migration of applications clustered using Microsoft Cluster Service (MSCS). o Other VMware products or features, such as VMware vApp and VMware Fault Tolerance, might override the automation levels of virtual machines in a DRS cluster. o An affinity rule specifies that two or more virtual machines be placed on the same host. An anti-affinity DRS rule is limited to two virtual machines, o If two rules conflict, the older one will take precedence, and the newer rule is disabled. o Disabled rules are ignored. DRS 220 701 gives higher precedence to preventing violations of anti-affinity rules than violations of affinity rules. o When a host machine is placed in standby mode, it is powered off. o Hosts are placed in standby mode by the VMware DPM feature o A cluster becomes overcommitted (yellow) when the cluster does not have the capacity to support all resources reserved by the child resource pools. Typically this happens when cluster capacity is suddenly reduced. o A cluster enabled for DRS becomes invalid (red) when the tree is no longer internally consistent, that is, resource constraints are not observed. o VMware DPM can use one of three power management protocols o IPMI - Intelligent Platform Management Interface o iLO - Hewlett-Packard Integrated Lights-Out o WOL - Wake-On-LAN o If a host supports multiple protocols, they are used in the following order: IPMI, iLO, WOL. o The VMotion NIC on each host must support WOL to use that protocol. o The DRS threshold and the VMware DPM threshold are essentially independent. You can differentiate the aggressiveness of the migration and host-power-state recommendations. o Verify that DPM is functioning properly by viewing each host’s Last Time Exited Standby information. o The most serious potential error you face when using VMware DPM is the failure of a host to exit standby mode when its capacity is needed by the DRS cluster. Use the preconfigured Exit Standby Error alarm for this error. o DRS Recommendations have 5 levels (1-5). Priority 1, the highest, indicates a mandatory move because of a host entering maintenance or standby mode or DRS rule violations. Other priority ratings denote how much the recommendation would improve the cluster’s performance; o Prior to ESX/ESXi 4.0, 220 702 recommendations received a star rating (1 to 5 stars) instead of a priority level. o Non-Uniform Memory Access (NUMA) systems are advanced server platforms with more than one system bus. o Some virtual machines are not managed by the ESX/ESXi NUMA scheduler: if you manually set the processor affinity for a virtual machine, or virtual machines that have more virtual processors than the number of physical processor cores available on a single hardware node. o When a virtual machine is powered on, ESX/ESXi assigns it a home node. This is initially assigned to home nodes in a round robin fashion.

Appendix B – Linux Commands Used with ESX Appendix C – Using vmkfstools o vmkfstools utility is used to create and 640-802 manipulate virtual disks, file systems, logical volumes, and physical storage devices. Fibre Channel SAN Configuration Guide o Zones define which HBAs can connect to which SPs. o Zoning is similar to LUN masking, which is commonly used for permission management. Usually, LUN masking is performed at the SP or server level. o WWPN (World Wide Port Name) is a globally unique identifier for a port. o Port ID (or port address) enables routing. FC switches assign the port ID when the device logs in to the fabric. o When N-Port ID Virtualization (NPIV) is used, a single FC HBA port (N-port) can register with the fabric by using several WWPNs. o active-active - access to the LUNs simultaneously through all the storage ports that are available, without significant performance degradation. o active-passive - one port is actively providing access to a given LUN. The other ports act as backup o Disk shares are relevant only within a given ESX/ESXi host. o Virtual machine I/O might be delayed for up to sixty seconds while path failover takes place. I/O delays might be longer on active-passive arrays. o On virtual machines running Microsoft Windows, increase the value of the SCSI TimeoutValue parameter to 60. o Only one VMFS volume per LUN. o Unless you are using diskless servers, do not set up the diagnostic partition on a SAN LUN. o ESX/ESXi does not support FC connected tape devices. o You cannot use virtual machine logical-volume manager software to mirror virtual disks. Dynamic disks on a Microsoft Windows virtual machine are an exception, but require special configuration. o You should not mix FC HBAs from different vendors in a single server. o Use a dedicated SCSI adapter for any tape drives that you are connecting to an ESX/ESXi system. o You should not use boot from SAN 640 802 braindumps in the following situations: o If you are using Microsoft Cluster Service. o If I/O contention might occur between the service console and VMkernel. o Proper LUN masking is critical in boot from SAN mode. o Runtime Name - the name of the first path to the device. Created by the host. Is not a reliable identifier for the device, and is not persistent. o vmhba#:C#:T#:L#, where: o vmhba# is the name of the storage adapter o C# is the storage channel number. o T# is the target number. o L# is the LUN number o If a target has only one LUN, the LUN number is always zero (0).

You cannot use IDE/ATA drives to store virtual machines. o Use local SATA storage, internal and external, in unshared mode only. o Some SAS storage systems can offer shared access o You can have up to 256 VMFS datastores per system, with a minimum volume size of 1.2GB. o Grow the existing datastore extent if the storage device where your datastore resides has free space. You can vcp 4 grow the extent up to 2 TB. o You can connect up to 32 hosts to a single VMFS volume. (EDIT: Maximums document says 64) o Perform a rescan each time you: o Create new LUNs on a SAN. o Change the path masking on a host. o Reconnect a cable. o Make a change to a host in a cluster. o Do not rescan when a path is unavailable. o To rescan adapters on all hosts managed by vCenter by right-clicking a datacenter, cluster, or folder and selecting Rescan for Datastores. o ESX does not support the delegate user functionality that enables access to NFS volumes using non-root credentials o Disk format on a NAS device is dictated by the NFS server, typically a thin format that requires on-demand space allocation. o When your host accesses a virtual machine disk file on an NFS-based datastore, a .lck-XXX lock file is generated to prevent other hosts from accessing this file. o If the underlying NFS volume, is read-only, make sure that the volume is exported as a read-only share by the NFS server, or configure it as a read-only on the ESX host. o A diagnostic partition cannot be located on an iSCSI LUN accessed through a software iSCSI initiator. o You can query and scan the host’s diagnostic partition using the vicfg-dumppart -l command o You can group datastores into folders. o You can unmount: o NFS datastores o VMFS datastore copies mounted without resignaturing o You can have up to 32 extents. o You can grow an extent in an existing VMFS datastore. Only extents with free space immediately after them are expandable. o If a shared datastore has powered vmware vcp 4 on virtual machines and becomes 100% full, you can increase the datastore's capacity only from the host, with which the powered on virtual machines are registered. o You can mount a VMFS datastore only if it does not collide with an already mounted VMFS datastore that has the same UUID (signature). o When resignaturing a VMFS copy, ESX assigns a new UUID and a new label to the copy, and mounts the copy as a datastore distinct from the original. o The default format of the new label assigned to the datastore is snap--, where is an integer and is the label of the original datastore. o Datastore resignaturing is irreversible. o A spanned datastore can be resignatured only if all its extents are online. o Pluggable Storage Architecture (PSA) is an open modular framework that coordinates the simultaneous operation of multiple multipathing plugins (MPPs). The VMkernel multipathing plugin that ESX provides by default is the VMware Native Multipathing Plugin (NMP). Two types of NMP subplugins, Storage Array Type Plugins (SATPs), and Path Selection Plugins (PSPs). o The VMware NMP supports all storage arrays listed on the VMware storage HCL and provides a default path selection algorithm based on the array type. o ESX offers an SATP for every type of array that VMware supports. o By default, the VMware NMP supports the following PSPs: o Most Recently Used (MRU) o Fixed - with active-passive arrays that have a Fixed path policy, path thrashing might be a problem. o Round Robin (RR) - Uses a path selection algorithm that rotates through all available paths enabling load balancing across the paths. o Claim rules defined in the /etc/vmware/esx.conf file, the host determines which multipathing plugin (MPP) should claim the paths. o By default, the host performs a 640 802 periodic path evaluation every 5 minutes. o Active multiple working paths currently used for transferring data are marked as Active (I/O). In ESX 3.5 or earlier, the term active means the only path that the host is using to issue I/O to a LUN. o Standby path is operational and can be used for I/O if active paths fail. o If you created a virtual disk in the thin format, you can later inflate it to its full size. o RDM offers several benefits. User-Friendly Persistent Names, Dynamic Name Resolution, Distributed File Locking, File Permissions, File System Operations, Snapshots, vMotion, SAN Management Agents and N-Port ID Virtualization(NPIV). o Certain limitations exist when you use RDMs: o Not available for block devices or certain RAID devices. o Available with VMFS-2 and VMFS-3 volumes only. o No snapshots in physical compatibility mode. o No partition mapping. It requires a whole LUN.

o MAC Address Changes - the guest OS changes the MAC address of the adapter to anything other than what is in the .vmx o Forged Transmits - Outbound frames with a source MAC address that is different from the one set on the adapter are dropped. o Traffic shaping o Traffic shaping policy is defined by three characteristics: average bandwidth, peak bandwidth, and burst size. o ESX shapes outbound network vcp-410 traffic on vSwitches and both inbound and outbound traffic on a vNetwork Distributed Switch. o Peak bandwidth cannot be less than the specified average bandwidth. o NIC Teaming (Load balancing and failover) o Load Balancing 1. Route based on the originating port ID — Choose an uplink based on the virtual port where the traffic entered the virtual switch. 2. Route based on ip hash — Choose an uplink based on a hash of the source and destination IP addresses of each packet. 3. Route based on source MAC hash — Choose an uplink based on a hash of the source Ethernet. 4. Use explicit failover order — Always use the highest order uplink from the list of Active adapters which passes failover detection criteria. o IP-based teaming requires that the physical switch be configured with etherchannel. For all other options, etherchannel should be disabled. o Incoming traffic is controlled by the load balancing policy on the physical switch o Network failover detection o Link Status only o Beacon probing - Do not use beacon probing with IP-hash load balancing. o Notify Switches - a notification is sent out over the network to update the lookup tables on physical switches. In almost all cases, this process is desirable for the lowest latency of failover occurrences and migrations with VMotion. Do not use this option when the virtual machines using the port group are using Microsoft Network Load Balancing in unicast mode. o Failback - determines how a physical adapter is returned to active duty after recovering from a failure. If failback is set to Yes (default), the adapter is returned vmware vcp 410 to active duty immediately upon recovery. o Failover Order 1. Active Uplinks 2. Standby Uplinks 3. Unused Uplinks o When using IP-hash load balancing, do not configure standby uplinks. o VLAN - The VLAN policy allows virtual networks to join physical VLANs - vNetwork Distributed Switch only (dvPorts). o Port blocking policies - vNetwork Distributed Switch only (dvPorts). o VMware uses the Organizationally Unique Identifier (OUI) 00:50:56 for manually generated addresses. You must set them in a virtual machine’s configuration file: ethernet.addressType="static" o Jumbo frames must be enabled at the host level using the command-line interface to configure the MTU size for each vSwitch. o TCP Segmentation Offload (TSO) is enabled on the VMkernel interface by default, but must be enabled at the virtual machine level. o To enable TSO at the virtual machine level, you must replace the existing vmxnet or flexible virtual network adapters with enhanced vmxnet virtual network adapters. This might result in a change in the MAC address of the virtual network adapter. o To check whether TSO is enabled on a particular VMkernel networking interface use the esxcfg-vmknic -l command. The list shows each TSO-enabled VMkernel interface with TSO MSS set to 65535. o If TSO is not enabled for a particular VMkernel interface, the only way to enable it is to delete the VMkernel interface and recreate the interface. o Jumbo frames up to 9kB (9000 bytes) are supported. o Use the vicfg-vswitch -m command to set the MTU size for the vSwitch. o Enabling jumbo frame support on a virtual machine requires an enhanced vmxnet adapter for that virtual machine. o NetQueue in ESX takes advantage of the capability of some network adapters to deliver network traffic to the system in multiple receive queues that can be processed separately. This allows processing to be scaled to multiple CPUs, improving receive-side networking performance. o NetQueue is enabled by default. o ESX supports a direct PCI vmware vcp 4 device connection for virtual machines running on Intel Nehalem platforms. Each virtual machine can connect to up to 2 passthrough devices. o The following features are unavailable for virtual machines configured with VMDirectPath: o VMotion o Hot adding and removing of virtual devices o Suspend and resume o Record and replay o Fault tolerance o High availability o DRS (limited availability; the virtual machine can be part of a cluster, but cannot migrate across hosts) o Software-initiated iSCSI is not available over 10GigE network adapters in ESX.

By default, statistics are stored in the vCenter Server database for one year. You can increase this to three years. o You cannot view datastore metrics in the advanced charts. They are only available in the overview charts. o CPU Performance Enhancement Advice 1. Verify that VMware Tools is Passed VCP410 installed on every VM on the host. 2. Compare the CPU usage value of a VM with the CPU usage of other VMs on the host or in the resource pool. The stacked bar chart on the host's Virtual Machine view shows the CPU usage for all VMs on the host. 3. Determine whether the high ready time for the VM resulted from its CPU usage time reaching the CPU limit setting. If so, increase the CPU limit on the VM. 4. Increase the CPU shares to give the VM more opportunities to run. The total ready time on the host might remain at the same level if the host system is constrained by CPU. If the host ready time doesn't decrease, set the CPU reservations for high-priority VMs to guarantee that they receive the required CPU cycles. 5. Increase the amount of memory allocated to the VM. This decreases disk and or network activity for applications that cache. This might lower disk I/O and reduce the need for the ESX/ESXi host to virtualize the hardware. Virtual machines with smaller resource allocations generally accumulate more CPU ready time. 6. Reduce the number of virtual CPUs on a VM to only the number required to execute the workload. For example, a single-threaded application on a four-way VM only benefits from a single vCPU. But the hypervisor's maintenance of the three idle vCPUs takes CPU cycles that could be used for other work. 7. If the host is not already in a DRS cluster, add it to one. If the host is in a DRS cluster, increase the number of hosts and migrate one or more VMs onto the new host. 8. Upgrade the physical CPUs or cores on the host if necessary. 9. Use the newest version of ESX/ESXi, and enable CPU-saving features such as TCP Segmentation Offload, large memory pages, and jumbo frames. o Memory Performance Enhancement Advice 1. Verify that VMware Tools is installed on each VM. The balloon driver is installed with VMware Tools and is critical to performance. 2. Verify that the balloon driver is enabled. The VMkernel regularly reclaims unused VM memory by ballooning and swapping. Generally, this does not impact VM Passed VCP 4 performance. 3. Reduce the memory space on the VM, and correct the cache size if it is too large. This frees up memory for other VMs. 4. If the memory reservation of the VM is set to a value much higher than its active memory, decrease the reservation setting so that the VMkernel can reclaim the idle memory for other VMs on the host. 5. Migrate one or more VMs to a host in a DRS cluster. 6. Add physical memory to the host. o Disk I/O Performance Enhancement Advice 1. Increase the VM memory. This should allow for more operating system caching, which can reduce I/O activity. Note that this may require you to also increase the host memory. Increasing memory might reduce the need to store data because databases can utilize system memory to cache data and avoid disk access. To verify that VMs have adequate memory, check swap statistics in the guest operating system. Increase the guest memory, but not to an extent that leads to excessive host memory swapping. Install VMware Tools so that memory ballooning can occur. 2. Defragment the file systems on all guests. 3. Disable antivirus on-demand scans on the VMDK and VMEM (backup of the VM’s paging file) files. 4. Use the vendor's array tools to determine the array performance statistics. When too many servers simultaneously access common elements on an array, the disks might have trouble keeping up. Consider array-side improvements to increase throughput. 5. Use Storage VMotion to migrate I/O-intensive VMs across multiple ESX/ESXi hosts. 6. Balance the disk load across all physical resources available. Spread heavily used storage across LUNs that are accessed by different adapters. Use separate queues for each adapter to improve disk efficiency. 7. Configure the HBAs and RAID controllers for optimal use. Verify that the queue depths and cache settings on the RAID controllers are adequate. If not, increase the number of outstanding disk requests for the VM by adjusting the Disk.SchedNumReqOutstanding parameter. For more information, see the Fibre Channel SAN Configuration Guide. 8. For resource-intensive VMs, separate the VM's physical disk drive from the drive with the system page vcp 410 file. This alleviates disk spindle contention during periods of high use. 9. On systems with sizable RAM, disable memory trimming by adding the line MemTrimRate=0 to the VM's .VMX file. 10. If the combined disk I/O is higher than a single HBA capacity, use multipathing or multiple links. 11. For ESXi hosts, create virtual disks as preallocated. When you create a virtual disk for a guest operating system, select Allocate all disk space now. The performance degradation associated with reassigning additional disk space does not occur, and the disk is less likely to become fragmented. 12. Use the most current ESX/ESXi host hardware. o Networking Performance Enhancement Advice 1. Verify that VMware Tools is installed on each VM. 2. If possible, use vmxnet3 NIC drivers, which are available with VMware Tools. They are optimized for high performance. 3. If VMs running on the same ESX/ESXi host communicate with each other, connect them to the same vSwitch to avoid the cost of transferring packets over the physical network.
