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.

How to Recover Deleted Files (rm -rf) or Accidentally click Empty Recycle Bin

So, sometimes “shit” can happen. Accidentally do rm -rf in linux OS, or click empty recycle bin in windows. Or, disk is corrupt, boot sector is broken, etc. This is a very useful tool to help you to “try” to fix it. Sometimes it works, and sometimes it doesn’t. At least you try… 😉 Err, wrong emoticon, it should be 🙁

TestDisk is OpenSource software and is licensed under the terms of the GNU General Public License (GPL v2+).

TestDisk is powerful free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software: certain types of viruses or human error (such asaccidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy.

TestDisk can

  • Fix partition table, recover deleted partition
  • Recover FAT32 boot sector from its backup
  • Rebuild FAT12/FAT16/FAT32 boot sector
  • Fix FAT tables
  • Rebuild NTFS boot sector
  • Recover NTFS boot sector from its backup
  • Fix MFT using MFT mirror
  • Locate ext2/ext3/ext4 Backup SuperBlock
  • Undelete files from FAT, exFAT, NTFS and ext2 filesystem
  • Copy files from deleted FAT, exFAT, NTFS and ext2/ext3/ext4 partitions.

Important Message from Pat Gelsinger (CEO of VMware Inc.)

Last week, Pat sent a twitter message. I felt really grateful that he is the CEO of VMware (http://www.vmware.com/company).

“Remember, we work to live, not live to work. Hope you all get extra time with family”.

Thanks Pat for reminding us again about this (read: me)!

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

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 🙂

How to do agile Software Development menggunakan Scrum?

Berikut ini saya lampirkan penjelasan mengenai cara software development dengan mengimplementasikan metode scrum. Dimana scrum ini adalah salah satu metode/practice untuk mengimplementasikan agile software development. Saya membuat slide ini beberapa tahun yang lalu, saya rasa masih sangat relevan untuk dunia saat ini. Bahkan, saya rasa lebih relevan untuk diimplementasikan saat ini daripada dulu!

Pada seri berikutnya, akan saya lampirkan juga tools apa yang saya gunakan waktu mengimplementasikan scrum ini di team saya.

 

Selamat menikmati 🙂

Bagaimana membuat agile Infrastructure untuk mendukung dunia Aplikasi yang agile

Berikut ini adalah beberapa slide presentasi lama yang saya buat (waktu saya masih kerja di IBM Indonesia), saya simpan di Slideshare (saat ini sudah diakusisisi oleh Linkedin sebesar US$119M!)

Materi dari presentasi ini adalah, untuk kebutuhan Software Development. Saat ini mekanisme untuk pembuatan aplikasi sudah menuju ke tahapan “Dev-Ops”, dimana kecepatan untuk melakukan release ke production dari tahapan development sudah sangat cepat. Sehingga dibutuhkan infrastruktur yang juga agile, tidak hanya metodologi development-nya saja yang agile.

Actually ada beberapa slide yang membutuhkan penjelasan via whiteboarding session, mungkin nanti kalau sempat akan saya jelaskan lebih lanjut di blog ini.

 

Selamat menikmati 🙂

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.
