RAID is supported. However, you should ensure that your specific drive controller is included in the supported hardware.
Storage of virtual machines is currently not supported on IDE/ATA drives or RAIDs. Virtual machines must be stored on VMFS partitions configured on a SCSI drive, a SCSI RAID, or a SAN.
SCSI disk drives . SCSI disk drives are supported for installing ESX Server. They can also store virtual machines on VMFS partitions.
Storage area networks (SANs) . SANs are supported for installing ESX Server. They can also store virtual machines on VMFS partitions.

10. Enhanced Performance Recommendations for ESX Server
* Some recommendations for enhanced performance:

RAM : Having sufficient RAM for all your virtual machines is important to
achieving good performance. ESX Server hosts require more RAM than typical
Servers : An ESX Server host must be equipped with sufficient RAM to run
concurrent virtual machines, plus run the service console.

Dedicated fast Ethernet adapters for virtual machines : Dedicated Gigabit Ethernet cards for virtual machines, such as Intel PRO/1000 adapters,iimprove throughput to virtual machines with high network traffic.

Disk location . For best performance, all data used by your virtual machines should be on physical disks allocated to virtual machines. These physical disks should be large enough to hold disk images to be used by all the virtual machines.

VMFS3 partitioning . For best performance, use VI Client or VI Web Access to set up your VMFS3 partitions rather than the ESX Server installer. Using VI Client or VI Web Access ensures that the starting sectors of partitions are 64K aligned, which improves storage performance.

Processors . Faster processors improve ESX Server performance. For certain workloads, larger caches improve ESX Server performance.

Hardware compatibility . To ensure the best possible I/O performance and workload management, VMware ESX Server provides its own drivers for supported devices. Be sure that the devices you plan to use in your server are supported.

Fast Solution to Get a High Paying Job in the Best Technology Company

Is there a fast solution to get a Good job?

Can I somehow get a very good salary job fast?

What should I do to get that dream job soon ?

These are some of the questions many people email me with & people search frequently online. I am trying to list solutions,answers for these questions.

1.Best Time Management : Get to know Which company pays highest & Which profile does it pay a very good salary for.

2.Learn Fast Retain most : If you already suit above profile then you are lucky if not then you need to learn lots of stuff fast & also should retain a lot. More than anything a company wanna hire an experienced expert & not some one very good in theory. So u need to work fast, work smart & then learn from others experience. Internet helps u a lot in this. An example is this blog which has lots of interview questions highlighting what topics to stress more.Also videos which explain & show the things. In future I will write about tech topics along with their practical configuration etc which are practical.

3.Have a good Support System : Who can get you inside information or can help you get some advantage like who can teach you Server administration in a crash course, who can let you know which company is hiring in your nearby place, who can help you know how you can setup your own scaled down storage lab etc etc . You basically need someone who is more than a good friend.

4.Stick to the goal & be very positive : Results will not happen in a day. So you need to have consistency in your efforts. If I say read all 100+ posts on this blog & you will get a job for sure - how many of this blog's readers will try that. I am sure not even 1 person can have the patience to read all 100+ posts on this blog. But to my amazement a guy from Japan has gone through all the posts on this blog & taken print out made it as a small reference book. He emailed me yesterday saying that he got a nice job since he used this blog as his support system. Yes for him this blog served the purpose of being more than a friend. I am glad someone made a very positive use of the amount of knowledge available on this blog.

If you feel its tough to read all 100+ posts then read the important ones atleast the interview questions related blog posts , which I'm listing below :
