Berapa Lama untuk melakukan migrasi dari server Physical to Virtual (P2V)?

Pada saat kita memutuskan untuk melakukan konversi ke vSphere Virtual Machine, akan ada proses untuk melakukan konversi dari physical machine atau virtual machine yang sebelumnya.
Kita biasa sebut sebagai Pyhysical to Virtual (P2V) atau Virtual to Virtual (V2V).

Ketika kita ingin menggunakan P2V/V2V, maka metode konversi ini akan melalui jaringan data. Biasanya paling rendah antara source dan destination menggunakan 1Gbps koneksi.
Tetapi jika environment network ini di-share dan tidak dedicated, kemungkinan throughput yaitu antara 20GB s/d 50GB data yang bisa ditransfer dalam 1 jam (perlu dianalisa langsung pada environment customer).
Proses konversi hanya akan mengirim data yang ter-utilisasi saja, misal jika disk besarnya adalah 300 GB tetapi hanya terisi 100 GB, maka data yang dikirim hanya 100 GB saja.

Berikut ini adalah rumus transfer:
Jumlah Data yang ditransfer = Jumlah VM atau Server x Jumlah Besar Disk x Utilisasi Disk

Waktu yang dibutuhkan = Jumlah Data yang ditransfer / Estimasi Throughput

Contoh:
Jika data yang ditransfer besarnya adalah 10 TB, dan throughput adalah 50 GB/hour. Maka waktu yang dibutuhkan adalah 200 jam (8 jam). Dengan asumsi kecepatan pengiriman data stabil.

Urutan dalam melakukan Backup untuk VMware vRealize Suite

Untuk sistem skala Enterprise, urutan backup adalah sesuatu yang penting untuk menjaga data consistency. Kita perlu menjamin bahwa dependency antara VM satu dengan yang lain selalu terjaga, sehingga pada saat recovery tidak ada data yang missing.

Jika anda mengimplementasikan backup secara otomatis, maka urutan backup ini dapat diatur di backup tools yang anda gunakan (ex: Symantec NetBackup)

Berikut ini adalah urutan backup yang direkomendasikan untuk dijalankan satu persatu pada saat  backup berlangsung:

  1. 1). vRealize Business
  2. 2). vRealize Log Insight
  3. 3). vRealize Operations Manager
  4. 4). vRealize Orchestrator
  5. 5). vRealize Automation (jika VRA arsitekturnya distributed, backup juga perlu berurutan)
    1. a). Proxy Agents
    2. b). DEM Workers
    3. c). DEM Orchestrator
    4. d). Manager Services (backup yang passive dulu, baru aktif)
    5. e). Websites (backup node1, node2, dst)
    6. f). vRealize Automation Appliance (backup secondary node, baru primary)
    7. g). SSO (Identity Appliance)
    8. h). PostgreSQL
    9. i). MS SQL
    10. j). Backup Load Balancers

Bagaimana? Cukup rumit bukan? Enggak ah, simple enough kok 🙂

Sekarang, setelah dibackup. Pasti akan direstore dan Power On the VM. Urutannya tinggal dibalik saja dari urutan backup keatas. Jadi tinggal dibaca dari bawah ke atas.

Oracle Real Application Cluster Pros-Cons Analysis on vSphere

There are several considerations, whether we want  to implement Oracle Real Application Cluster or not in vSphere environment. These are some simple writings of the Pros and Cons analysis.

 

Pros Analysis – Oracle RAC on vSphere Cons Analysis – Oracle RAC on vSphere
Availability perspective: It will create zero downtime of availability (but VMware already has VMware HA features) if customer thinks that the VMware HA feature is good enough (approximately 5 minutes RTO) then no need to consider RAC for availability option. Cost perspective: customer need to purchase additional licenses for Oracle RAC capabilities for each cores of the servers in the database cluster.
Performance perspective: it “might” help the database performance if needed. But, some DBs can have better performance with RAC, some don’t (ex: batch processing intensive application). It depends on the architecture of the application itself (need to be tested). Manageability perspective: It will create additional complex things to manage (such as oracle clusterware, ASM disks, and additional RAC processes).
Recoverability perspective: it will create zero downtime experience, if the failure is happening on the host. But, if the failure is happening on the shared storage connection then recovery process need to be conducted from backup or disaster recovery mechanism. Resource perspective: customer will need to create min 2 VMs for each DB in different ESXi hosts for full capability of RAC, anti-affinity should be configured so the VMs won’t start in the same host.

So, basically the decision will be on your hand. Whether you are willing to “pay the price” for the features that you “need”. Ask the question again: do you really need the features?

Key Factors to create Perfect Design for VMware vSphere Infrastructure

If you are doing vSphere Design right now. Please remember this AMPRS rule for your design document.

Always think your design decision based on these key factors. Availability, Manageability, Performance, Recoverability, and Security.

Especially if it is for Business Critical Application, then you MUST consider all these factors.

 

Design Quality Description
Availability Indicates the effect of a design choice on the ability of a technology and the related infrastructure to achieve highly available operation.

Key metrics: percent of uptime.

Manageability Indicates the effect of a design choice on the flexibility of an environment and the ease of operations in its management. Sub-qualities might include scalability and flexibility. Higher ratios are considered better indicators.

Key metrics:

·         Servers per administrator.

·         Clients per IT personnel.

·         Time to deploy new technology.

Performance Indicates the effect of a design choice on the performance of the environment. This does not necessarily reflect the impact on other technologies within the infrastructure.

·         Key metrics:

·         Response time.

·         Throughput.

Recoverability Indicates the effect of a design choice on the ability to recover from an unexpected incident which affects the availability of an environment.

Key metrics:

·         RTO – Recovery time objective.

·         RPO – Recovery point objective.

Security Indicates the ability of a design choice to have a positive or negative impact on overall infrastructure security. Can also indicate whether a quality has an impact on the ability of a business to demonstrate or achieve compliance with certain regulatory policies.

Key metrics:

·         Unauthorized access prevention.

·         Data integrity and confidentiality.

·         Forensic capabilities in case of a compromise.

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.

Can find the posts from these links :

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.

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

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
