"This script performs backups of virtual machines residing on ESX 3.5+ and ESXi servers using methodology similar to VMware's VCB tool. The script takes snapshots of live virtual machines, backs up the master VMDKs and then upon completion, deletes the snapshot until the next backup. The only caveat is that it utilizes resources available to the Service Console of the ESX server running the backups as opposed to following the traditional method of offloading virtual machine backups through a VCB proxy."

You can find more information about the script here.

Trilead VM Explorer is a management tool that eases management, backup and disaster recovery tasks in your VMware ESX Server environment. You get maximum flexibility: backups can be stored to ESX, Windows, Linux and FreeBSD based storage platforms or directly to a SAN.

Features:

  • Multi-Server Management: The graphical user interface of VM Explorer allows to connect to multiple ESX, Linux and FreeBSD servers at the same time in the same interface.

  • Server to Server fast copy: Allows you to copy files directly (drag&drop) between ESX, Linux and FreeBSD servers at full speed: throughput is only limited by the available network/storage system bandwidth.

  • ESX to ESX/Windows/Linux/FreeBSD/SAN Backup & Restore: Our unique ESX to any backup feature allows to backup virtual machines to other ESX Servers, Linux or FreeBSD servers. Of course, virtual machines can also be stored to a SAN (ISCSI or NFS) directly attached to an ESX. Furthermore, backups can also be saved on the Windows machine where the VM Explorer is running.

  • Support for ESX 3i: VMX version 1.5 includes beta support for the next generation of ESX servers.

  • File Browser: Browse instantly your ESX/Linux/FreeBSD servers' file system and copy files from one to the other just by drag & drop. Supports also up- and download to the management station.

  • Integrated SSH Client: The integrated SSH Terminal Client allows you to configure all your Unix/Linux based Servers trough SSH, all within one software.

  • Job Scheduler: The integrated job scheduler allows you to perform unattended, periodic backups of your virtual infrastructure.

  • Integrated ESX Snapshot Manager: Create and remove snapshots directly from within VMX.

  • Dynamic Compression: To make use of slow network links (e.g., for wide-area replication) or to save space on the target system, backups can be dynamically compressed.

Great post from Chad at Virtual Geek:

"Glad to see that people are having downloading and success with the Celerra VM on VMware Workstation based on this original post.  I wanted to provide a quick "HOWTO" to help customers Replicate between two VSAs, for many reasons - one of the most fun being VMware Site Recovery Manager.

Celerra Replicator (I hope the Celerra Product team doesn't read this) is a RIDICULOUSLY inexpensive (particularly when compared with the competition) but very sophisticated remote replication capability."

From Yellow Bricks (Duncan Epping):

I’ve been doing VMware Design Reviews lately and so are my colleagues of the PSO department. A Design Review is quick scan of your design documentation by a VMware consultant. The consultant will hold your docs against best practices and propose changes to the design.

One of the things we encounter on a regular base is that admins took the easy path for their Storage Design zoning. So what’s zoning? In short: a way to partition your fabric into smaller subsets. These small subsets provide you with a better security and less interference...

This is an interesting post Leo Raikhman wrote about the ESX / VC installation best practices:

I get asked this all the time: what is best practice installation procedure?

I don’t know that there is such a thing - every environment is slightly different but here’s my general outline for ESX 3.5 + VirtualCenter 2.5 attached to Fibre SANs.

Installing VirtualCenter 2.5:

  • Install SQL 2005 + SQL Native Client
  • Patch SQL 2005 to SP2 + associated updates
  • Enable SQL clustering if relevant.
  • Create SQL DB with SQL-authenticated user as db_owner for the msdb and newly created databases (for VMware VirtualCenter and VMware Update Manager)
  • Create an ODBC connection with above information on targeted VC server
  • Install VirtualCenter
  • Add VirtualCenter server IP to Exchange Relay Access rulesets
  • Configure VirtualCenter SMTP settings, alarm definitions and Message of the Day
  • Copy/install sysprep/deployment tools files
  • Create required customizations
  • Create a datacenter object
  • Create a cluster object
  • Configure HA + advanced HA with VM HA monitoring
  • Configure DRS + separation rules
  • Install Update Manager - sync ESX host updates with VMware downstream servers
  • Configure VirtualCenter certificates as per this article from the excellent VM/ETC

Back in February I wrote a post about the VMware Tools and Utilities I use to administer our VMware environment. Now, via vmware-land.com we get the following list:

1-Putty - Telnet and SSH client for remotely connecting to the ESX service console
2-WinSCP and Veeam FastSCP - SCP clients for browsing ESX server file systems and transferring files to/from ESX hosts
3-VI3 SnapHunter and SnapAlert - Utilities that can report all running snapshots on ESX hosts including name, size and date. Can also automatically email reports and optionally commit snapshots
4-VI Scripted Backup Utility - A backup utility that is run from the Service Console that provides VMDK level backups of any VM on storage accessible by the host
5-MCS StorageView - A utility that displays all the logical partitions, operating system, capacity, free space and percent free of all virtual machines on ESX 3.x or Virtual Center 2.x
6-SSH Plug-in - A VI client plug-in that integrates an SSH console directly into the client
7-Storage VMotion Plug-in - A VI client plug-in that extends the client’s functionality by providing an integrated, graphical tool that can be used to invoke storage VMotion (SVMotion) operations
8-VMotion Info - A program that will collect Vendor, Model, CPU Types and the CPU feature bits from all hosts to check for VMotion compatibility
9-VMCdConnected - Scans all Virtual Machines and shows if they have a CD connected to it. After scanning the VM’s you can disconnect all the CD’s with a click of a button
10-VMware Converter – (Performs hot and cold conversions of physical and virtual servers to virtual machines. Also converts image formats

Enjoy!

"The Xtravirt Virtual SAN (XVS) appliance for VMware ESX3 Server, is a free solution to provide the benefits of shared VMFS storage without the cost of a SAN – this allows the utilization of otherwise unused local storage in the ESX server to facilitate enterprise level features such as VMotion, DRS and HA normally only available through the use of a shared storage device. All volume data is synchronously replicated between hosts, providing full fail-over capability with data integrity in the event of host, disk or appliance failure. The appliance is menu driven and has been designed to be as easy to configure as possible, and full documentation is provided."

Its features include:

  1. XVS is a SAN and local Disaster Recovery all-in-one
  2. It provides enterprise level functionality such as VMotion, DRS, and HA, all using direct attached storage
  3. All volume data is synchronously replicated between hosts providing full failover capability with data integrity in the event of a host, disk or appliance failure
Download the Xtravirt Virtual SAN here.

"We know that ESX can handle a large number of IOPS, but we set out to see just how far we could push it. We went to EMC and got as many storage arrays as we could lay our hands on. We picked a realistic workload of 100% random with a 50/50 read/write mix and 8KB block size and then fired it up. We kept pushing more and more IOPS and managed to get up to 100,000 IOPS before running out of storage array bandwidth. And we still had plenty of headroom to spare with ESX!"

A while ago I wrote a post about the tools I use everyday to manage our VMware environment and about Veeam Backup. FastSCP was updated this week and now it includes the following new features:

  • Disk space pre-allocation
    When copying virtual machines, FastSCP will pre-allocate disk space for VMDK files, to prevent fragmentation.
  • Ability to edit file attributes
    FastSCP shows the properties for a file or folder, allowing users to set owner, group and permissions (the most common CHMOD commands) in a Windows GUI.
  • Scheduled copy
    Now you can schedule copy jobs to do VM migrations over night or to regularly backup ESX configuration files.
  • Integration with Veeam Backup
