my knoleght about storage is low and i whould like your recommention for storage for 500 users network with low budget organization.

1.what do u recomment for low-end storage with low budge to give me the best cost/effective solution for network with 16 servers and 500 users?

2.what are the specefication i need to search for, what is MUST have and what i should have...

like... hardware based solution, snapshot abillity... what are the Criterias i need to search for the storage solution?

speed is importent , larg capacity, good brand, good snapshot abbilty and simplicity...

what do u reccomend?

ones again i know that to get all i need something exprencive but i tring to search for solution that can much my bught (up to 6000- 10000 $)

You've left out one CRUCIAL bit of information.  How much storage do you need?  "Large capacity" is VAGUE.  To me, that could mean a 2 TB and to someone else that could be 50 TB.

well...not that large...

up to 5 TB will be good enoght....

Dell's Equallogic line is pretty cost effective for the small to mid range, they come with snapshot and replication licensing (all license features are always included).  I don't know if the $30k range was what you were looking for but you have no mention of the throughput needed (a single 1g/s NIC vs. multiple 8g/s fibre channel connections for example).  You can go down in performance/features from there but will start missing things that others might call critical.  

Oh, wait, you told us the cap was $10k, I am not sure but if you call Dell and CDW you can talk it through with their storage folks and find an appropriate solution I am guessing.  Your setup sounds pretty big for pinching pennies though.  We are tiny in comparison and have 2 SANs, one Equallogic and an EMC CX4-120 so I am the wrong person to ask, lol.

a lot of people just get a quality late model used server (with ecc memory, and lots of it for read cache)...  then use solaris with zfs based raid.  
.this has iscsi dedup all the services you need.
hot snapshot and backup also..
you can even do online expansion of your shared volumes

It might be pushing your budget, but the HP P2000 offers everything you need --
- iSCSI controllers for inexpensive connectivity over gigabit Ethernet
- hardware-based snapshots
- a nice browser-based user interface for configuring and presenting LUNs
- one- or two-controller configurations (if budget's a real issue, maybe start with one controller and update to a second for redundancy next year?)
- very expandable -- start with a single shelf with SAS disks for performance and reliability, add additional shelves later as your capacity needs grow, including SATA disks that are cheaper (but not designed for 24x7 use)
- if it comes up later, you could add a second unit at a remote location and use the snapshot-based replication

See details at http://www.hp.com/go/p2000

One thing to be aware of -- snapshots are not backup.   You'll almost certainly still need some way to get the data offsite.  Physical tape is typically a great way to do this.   Snapshots won't get you back from all failures, such as certain corruption, fire, earthquake, flood, theft, malicious acts, ...   If your data is important, back it up!    (I've recently heard about some arrays that start to delete snapshots when the storage fills up... good luck if it's a virus or malware that's filling up your system with garbage writes!)

Another thing to remember about snapshots is that, by default, a SAN does not necessarily quiesce the VMs on the LUN.  

About how to 'properly' snapshot a VM

Info about why a SAN that does not interact with ESX can't always get a consistent snapshot

Not sure if you know this but imagine your PC had its system drive on a SAN and you could take a quick image of the drive...quick is ok but if your drive is doing something while the snapshot happens then you are not getting a state consistent backup...more of a crash consistent image (more like if you yank the power cord and do a disk duplication of the drive).  Windows will come back up but if you were writing any data to a file then it might not be in good shape when you are done.  
In a perfect world your SAN would tell ESX to quiesce the guests before snapping each VM.  I just want to make sure you are going down the right road because relying on a crash consistent backup of a server is not always the best plan IMO.

Split between all experts who responded.  The question was vague enough in that all expert responses were valid as they fit within the constraints required by the author.
