How to Execute External Guest OS Script from VRO and VRA

These two posts explain the mechanism really well to extend VRA (VMware vRealize Automation) with VRO (VMware vRealize Orchestrator) to execute external script that is located in the External Guest Operating System folders (either Windows or Linux).

It is really useful if you want to execute one of these use cases :
– Silent Installation of Database/Apps platform (ex: SQL Server, Oracle DB, MySQL, PostgreSQL  Apache, etc after the VM is deployed)
– Configure parameters in Apps, DB, Middleware, agents (ex: NetBackup agent, Oracle DB, Tomcat, Weblogic, etc) after the VM is deployed)
– Execute other external scripts that is located in Guest OS

Please note that you also can use it with VRO only, if you don’t want to automate the process from VRA.

Penjelasan mengenai my Computer Home Lab Facility untuk explore VMware Technology

Pada posting kali ini, saya ingin menampilkan home lab yang saya miliki untuk mengeksplorasi fitur2 VMware yang sangat banyak. Memiliki home lab yang “mumpuni” adalah penting bagi saya yang saat ini hidup dari dunia IT, lebih spesifiknya yaitu “IT Cloud” 😉

Ada tiga opsi yang saat  ini saya miliki untuk membuat Home Lab. Opsi pertama, yaitu menggunakan:
1). Public Cloud yang disediakan secara free oleh my company buat para employee-nya around the world. Cool!!!
2). Personal Home Lab yang disediakan oleh “kebaikan hati” istri saya yang mengijinkan saya untuk membeli ini
3). Portable Laptop yang disediakan kantor sebagai fasilitas resmi buat kerja dengan spesifikasi yang gahar! (beratnya juga gahar!!!)

Public cloud yang saya gunakan, tidak akan saya jelaskan lebih detail di posting ini. Tapi intinya fitur ini menggunakan produk dari VMware, yaitu VMware vCloud Director. Even though ada public cloud, tetapi personal home lab tetap saya gunakan karena koneksi internet di Indonesia (read, my home) is not stable enough untuk 100% relying on public cloud.

Berikut ini adalah deskripsi my home lab yang saya gunakan untuk “ngoprek” beberapa teknologi dari VMware, Oracle, Microsoft, RedHat, Quest, open source stuffs, dan beberapa produk lainnya yang menunjang hasrat hands-on-experience saya.

1. My Home Lab (PC Rakitan, baca: ngerakit berdua di toko komputer bareng kokoh mangga dua – what a memorable experience)

These are the Spec :

Wanna Upgrade my Home Lab!
Beberapa hari ini saya lagi “ngiler” dengan home-lab one of my best friend teman seperjuangan di VMware “Bayu Wibowo” yang baru saja purchase home lab-nya (kemarin baru datang) yang aduhai spec-nya dan yang penting murah biaya opex-nya (read, electricity consumption). Saatnya bikin proposal ke istri nih, kalau perlu pakai hitung2an TCO and ROI yang dipresentasikan secara formal 😀

Berikut ini adalah spec hardware yang dimiliki beliau:

3 buah SlimPC Shuttle DS81 (http://global.shuttle.com/news/productsDetail?productId=1767), dengan spesifikasi untuk tiap node sebagai berikut: –price list +/- Rp 8jt for each

Processor Intel® Core™ i3-4160 Processor 3.60 GHz
Hitachi 1TB SATA3 16MB 7200RPM
Plextor PCIe SSD M6M 128GB
Kingston SO-DIMM DDR3 16GB PC12800

atau sebenarnya bisa juga dengan pilihan menggunakan Intel-NUC (http://www.intel.com/content/www/us/en/nuc/overview.html) yang lebih “cantik” bentuknya (tapi agak lebih mahal).:

Finally…, Mamiii ada yang mau Papi omongin sebentar 🙂

VMware vSphere Replication – Bandwith and Overhead Explained (updated)

Bandwith yang dibutuhkan untuk vSphere Replication Technology

Berikut ini adalah cara menghitung Bandwidth untuk vSphere Replication for Teknologi Replikasi dari VMware :

Untuk lebih jelasnya, terdapat VMware Knowledge Based yang membahas mengenai hal ini, yaitu :

Summary dari artikel tersebut adalah :

Contoh kasus, jika ada 500 VMs, rata2 200GB disk (70% used), data change rate 5%-25%, RPO average 4 jam dibutuhkan bandwidth sebesar ~500Mbps. Tetapi jika data change ratenya diubah menjadi 10%-25% bandwidth yg dibutuhkan ~1Gbps, 2x-nya

Di vSphere Replication version 6.0 ada feature baru dengan compression untuk menghemat bandwidth https://blogs.vmware.com/vsphere/2015/03/vr-60-compression.html

For most replication workloads, you will likely see compression ratios of approximately 1.6:1 to 1.8:1.

Performance Overhead untuk vSphere Replication

Pada vSphere Replication ada sedikit performance overhead impact ke VM dan ke ESXi. Impact ke VM seitar 2-6% dan pada ESXi hosts sangat minim, ini juga ada dokumentasinya di FAQ berikut vSphere Replication Frequently Asked Questions: https://communities.vmware.com/docs/DOC-27800

Q: What performance information is available about VMware vSphere Replication?

A: Impact on virtual CPU performance for a virtual machine that is protected by vSphere Replication is approximately 2 to 6 percent. In nearly all cases, this is not an issue because the vast majority of virtual machines are not CPU constrained.

Q: What performance overhead exists on the source hosts?

A: The replication scheduler built into VMware vSphere uses an insignificant amount of CPU and memory to compute the replication schedule of all the virtual machines on the host.

Q: What performance overhead exists on the target hosts?

A: VMware vSphere® Replication virtual appliances receive the replication traffic. They utilize compute and networking resources in a manner similar to any other virtual machine. Additional storage load is placed upon the VMware vSphere hosts as vSphere Replication transfers replicated data to storage using the Network File Copy (NFC) protocol. During a full-sync operation, checksum calculation operations are distributed across multiple hosts to minimize CPU impact on any one host. Several factors influence where contention might occur. For example, if there is much bandwidth – 1Gbps, for example – the amount of NFC traffic might tax the host or even the underlying storage system.

STP may cause temporary loss of network connectivity when a failover or failback event occurs (1003804)

Symptoms

In a switched network environment which uses Spanning Tree Protocol (STP), you experience these symptoms:

  • An ESXi or ESX host temporarily loses network connectivity when a failover or failback event occurs.
  • Virtual machines temporarily lose network connectivity when a failover or failback event occurs.
  • A VMware High Availability (HA) isolation event occurs after one of the teamed NICs of the COS is unplugged and plugged in to a different port.

Resolution

STP is used to accomplish a loop-free environment. Every time a port state goes up, STP calculation occurs. As the result of the calculation, the switch ports are either set to a forwarding or blocking state to prevent a traffic loop. STP topology convergence has four states:

  • Blocking
  • Listening
  • Learning
  • Forwarding

When STP convergence is initiated it forces all of the physical switches in the STP domain to dump their forwarding tables and relearn the STP topology and all MAC addresses. This process can take between 30-50 seconds. During this time, no user data passes through the port. Some user applications can time out during this period. Connectivity is restored when the STP domain completes this convergence.

To prevent the 30-50 second loss of connectivity during STP convergence, perform one of these options:

  • To set STP to Portfast on all switch ports that are connected to network adapters on an ESXi/ESX host
    Portfast allows the ports to immediately be set back to the forwarding state and prevents the link state changes that occur on ESX/ESXi hosts from affecting the STP topology. Setting STP to Portfast prevents the 30-50 second loss of network connectivity.
    The command to set STP to Portfast depends on the model of the switch. As the command is different from model to model and vendor to vendor, c ontact your physical switch vendor for more detailed information on how to configure the same.
    For example:
    To set STP to Portfast on a switch, run the below command based on the switch model:

    • CISCO-IOS
      spanning-tree portfast (for an access port)
      spanning-tree portfast trunk (for a trunk port)
    • NX-IOS
      spanning-tree port type edge (for an access port)
      spanning-tree port type edge trunk (for a trunk port)
    • To set STP to Portfast on a Dell switch, run the command:
      spanning-tree portfast
    • HP switches use a feature called admin-edge-port, which works the same way as Portfast or RSTP.
      To enable admin-edge-port, run the command:
      spanning-tree port-listadmin-edge-port
  • To disable STP
    VMware does not typically recommend that you disable STP. However, to prevent this issue from occurring, it may be necessary to disable STP. Before you disable STP, contact your switch vendor.
    The command to disable STP depends on the switch. Contact your switch vendor for more detailed information.
    For example:
    To disable STP on a Nortel switch, run the command:
    config ethernet stg stp disable

Kumpulan Knowledge Based penting untuk VMware vSphere 6.0

Saat ini sudah launch beberapa bulan yang lalu vSphere 6.0, tetapi saat ini masih banyak pengguna vSphere yang masih menggunakan versi 5.5. Jadi kumpulan knowledge based ini sangat berguna untuk me-recap apa saja yang KB yang penting untuk versi 5.5 ini.

With this in mind, we have created the following list of Knowledgebase articles that are brand new, or have been updated for vSphere 5.5 You’ll notice lots of best practices KBs here.

The first grouping contains absolute ‘must know’ information, the second grouping gets a bit more into details.

Also not to be missed:

High Level Best Practice Configuration yang perlu dicek untuk VMware vSphere Production Environment

Berikut ini ada beberapa konfigurasi best practice yang perlu dicek untuk mengetahui apakah environment VMware yang anda miliki saat ini sudah appropriate atau  tidak untuk production level. Ini adalah guidance secara high level saja. Untuk detailnya perlu dijelaskan lebih lanjut, mudah2an dapat saya teruskan untuk beberapa komponen dibawah ini.

Component Recommended Action Item
Compute Configure firewall rules and ports according to best practices.
Compute VMware vSphere ESXi Shell and SSH access should be configured per the customer security and manageability requirements.
Datacenter Use vCenter Server roles, groups, and permissions to provide appropriate access and authorization to the VMware virtual infrastructure. Avoid using Windows built-in groups (Administrators).
Datacenter Tasks and Events Retention Policy set in the environment.
Datacenter Size with HA host failure considerations.
Datacenter Set up redundancy for the management port (either using a separate vmnic or a separate uplink) and an alternate isolation response gateway address (if appropriate) for more reliability in HA isolation detection.
Datacenter Maintain compatible and homogeneous (CPU and memory) hosts within a cluster to support the required functionality for vMotion, vSphere DRS, VMware vSphere Distributed Power Management (DPM), VMware vSphere HA, and vSphere FT.
Network Verify that there is redundancy in networking paths and components to avoid single points of failure. For example, provide at least two paths to each network.
Network Configure networking consistently across all hosts in a cluster.
Network If jumbo frames are enabled, verify that jumbo frame support is enabled on all intermediate devices and that there is no MTU mismatch.
Network Minimize differences in the number of active NICs across hosts within a cluster.
Network Configure networks so that there is separation of traffic (physical or logical using VLANs).
Network Use DV Port Groups to apply policies to traffic flow types and to provide Rx bandwidth controls through the use of Traffic Shaping.
Network Use Load-Based Teaming (LBT) to balance virtual machine network traffic across multiple uplinks.
Network Use Network I/O Control (NetIOC) to prioritize traffic on 10GbE network uplinks.
Network Adjust load balancing settings from the default virtual port ID only if necessary.
Storage Minimize differences in datastores visible across hosts within the same cluster or vMotion scope.
Storage NFS and iSCSI storage traffic should be separated physically (for performance) and logically (for security).
Virtual Machines Limit use of snapshots, and when using snapshots limit them to short-term use.
Virtual Machines Verify that VMware Tools is installed, running, and up to date for running virtual machines.
Virtual Machines Verify that virtual machines meet the requirements for vSphere vMotion.
Compute Avoid unnecessary changes to advanced parameter settings.
Datacenter Enable bidirectional CHAP authentication for iSCSI traffic so that CHAP authentication secrets are unique.
Datacenter Disconnect vSphere Clients from the vCenter Server when they are no longer needed.
Datacenter Maintain compatible virtual hardware versions for virtual machines to support vMotion.
Licensing Verify that adequate licenses are available for vCenter Server instances.
Licensing Verify that adequate CPU licenses are available for ESXi hosts.
Network Distribute vmnics for a port group across different PCI buses for greater redundancy.
Network Change port group security default settings for Forged Transmits, Promiscuous Mode, and MAC Address Changes to Reject unless the application requires the defaults.
Storage Use shared storage for virtual machines instead of local storage.
Storage Size datastores appropriately.
Storage Allocate space on shared datastores for templates and media/ISOs separately from datastores for virtual machines.
Storage Use Storage I/O Control (SIOC) to prioritize high importance virtual machine traffic.
Virtual Machines As a security enhancement initiative, disable certain unexposed features.
Virtual Machines Limit sharing console connections if there are security concerns.
Virtual Machines Allocate only as much virtual hardware as required for each virtual machine. Disable any unused or unnecessary or unauthorized virtual hardware devices.
Virtual Machines Consider using the latest virtual hardware version to take advantage of additional capabilities.
Virtual Machines Use the latest version of VMXNET that is supported by the guest operating system.
Virtual Machines Use reservations and limits selectively on virtual machines that need it. Don’t set reservations too high or limits too low.
Virtual Machines Select the correct guest operating system type in the virtual machine configuration to match the guest operating system.
