In a previous post, I described how you can configure a virtual proxy to access an iSCSI storage, in order to test DirectSAN backups. Veeam has an additional functionality, called Storage Snapshots, that improves even more DirectSAN backups performances when you have a supported storage. I’m going to show you in this post how you can configure it in your lab.

Test DirectSAN backups without a physical Veeam server
One of the nice features of Veeam Backup & Replication, when it comes to backup speed, is the possibility to use DirectSAN as its backup method on vSphere environments. This option offers the best performances, but has some precise requirements at the hardware level. It could be easy to comply with them in a production environment, but what if you want to test it in your lab, where usually hardware options are limited? Don’t worry, there is a solution!

Check the file system of your USB drive before using it as a backup target
One of the new features introduced in Veeam Backup & Replication 7.0 is the new “Backup Copy” job type. With it, an administrator can create a secondary location for his backups, without having to clone large backup files from the primary backups using tools like rsync or robocopy.
If you plan to use an external USB drive as your target for this kind of jobs, be sure to check the file system in use, before runnng into problems.

PernixData in my Lab: some performance tests
Few weeks ago I published an article titled “My new “I/O Test Virtual Machine”, telling you about the VM I built to run my performance tests for virtualized environments. After a first post running those tests against my “plain” Lab and its enhanced version using another server-side caching solution, many of you asked me if I was planning to do the same tests with PernixData. So i did, and here are my findings.

A closer look at SanDisk FlashSoft 3.1 for vSphere
Ho scoperto per la prima volta FlashSoft in occasione di Storage Field Day 3 a Denver: FlashSoft era stata acquisita da SanDisk nel Febbraio 2012, ed è stata sinceramente una sopresa scoprire che il colosso delle memorie Flash possedeva una divisione Enterprise, fatta di soluzioni come appunto FlashSoft e altre. Penso che come me, molti di voi hanno sempre abbinato il nome SanDisk alle memorie per dispositivi o alle chiavette USB…
Ho finalmente potuto dedicare un pò di tempo a studiare questa soluzione. Questo primo articolo è una descrizione del prodotto e delle sue caratteristiche.
