Cisco Catalyst 3560 vs Dell PowerConnect 6224

im looking to upgrade all my routers to GbE switch's but im debating between Cisco Catalyst 3560 or  Dell PowerConnect 6224.
my main requirements im trying to achive are:
stability and realibility  under heavy network traffic (70 workstation)
Qos realibility
Redundancy ?

what makes the cisco 3560 a better solution than the dell 6224? is the extra money worth?

All I will tell you, I bought 2 PowerConnect 5224 24 port gigabit switches for our server farm.  Things were OK for a while, until I started implementing Link Aggregation for servers.  First there was the limitation that I could only create 6 groups, which meant I couldn't actually build redundant links for all servers.  Then there was the fact that occasionally, the lacp(link aggregation control protocol) ports would simply stop passing traffic, and I would need to pop the server to a few other ports, tear down the lacp settings on the horked ports, reboot the switch and all would be OK.  When I would go to dell to check for updates, there were only two images to choose from despite the switch being released 2 years prior.  Neither addressed my issue.

I finally replaced the 5224s with 3560G's and haven't touched them since.  Dell buys whatever hardware some manufacturer churns out based on their sales needs.  Cisco develops hardware and software that works well, then they continue to support it and update the software to fix problems.  If your switching is mission critical, get Cisco.  If you don't mind having to bounce a switch in the middle of the workday every couple months, get the Dell.

I still use the 5224s for client gigabit switching.  Would let them anywhere near the servers though.

I've had too many clients buy Dell switches because they were so much cheaper. Then ended up throwing them in the dumpster within just a few months at most and replacing with Cisco.
Bottom line - you get what you pay for. You get the stability, performance, support and reliability that you are looking for with Cisco.

what feature does the cisco offer for redudancy, i will have 3 switchs

You have to be a little more detailed about your requirements. Cisco switches can support dual/hot swappable power supplies, dual/hot swappable CPU's, dual/hot swappable line cards, etc. You can get as $illy redundant as you want, or can afford, or just take low-end switches and keep a spare on hand.
How much down time can you afford?
Other features for redundancy include Etherchanneling, HSRP and Layer 3 dynamic routing. How far apart are your 3 switches going to be? How many ports required on each switch? Do you have fiber infrastructure to connect them together?

thank for the answer, here is more details
downtime during bussines hours absolute 0 ( can not afford a switch to freeze or whatever)
so i can have redundat power supply great.
what it a switch freezes how can i have a second switch take over the traffic or something similar is that what HSRP does?
all 4 switchs will be in the same buliding and same rack.

what solution do you recomend to use for high level of redundancy, (ex: 4 cisco 3560 with fiber uplink one to the other, HSRP enabled..etc..etc im newbie when comes to cisco switchs and technology acvaliable today)

One big CAT6500 chassis with dual power supplies, dual supervisor engines, dual data backplanes. Switch blades with enough 10/100/1000 + PoE if you need it so support your needs.
This is the only solution that is really designed for this type of 5-9's reliability.
What we typically put into situations where downtime is not an option is dual 6500's. Each 6500 has dual power supplies, but single supervisor. Every critical server is dual-homed one to each switch. Switches dual cross-connected with fiber not copper at either 1G each link or 10G with multiple 1G as backup. The switch is only as reliable as the power supply. UPS's, room UPS, generator, backup generator, etc. If you don't have the reliable power, there is no sense in spending money for redundant hardware.
If downtime is not an option, then you have to spend the buck$ to get there.
If the buck$ aren't there, the budget is too tight, then you have to decide where to compromise and how much will 1 hour of downtime cost vs the up front cost of preventing that 1 hour of downtime.

how about the CAT 4500 what are your toughts on that guy?
thank for all the answers i will distribuit the points

lrmooreCommented:
Cat 4500 is a good compromise between high availability and price.
Redundant power supplies and redundant supervisor modules supported in the 4507R.
You can always start with the chassis, one power supply and one supervisor module and add a 2nd of each later on.

There is no such thing as zero downtime.  As lrmoore suggests, trying to get to the 5-9's (99.99999% uptime) is an expensive endeavor.  To me it is only appropriate when lives, or $millions are at stake.  You could do a pretty decent redundant setup by dual homing all of your systems to different 3560G's.  It really boils down to a cost benefit analysis.  Is downtime going to lose money, if so how much per hour.  If downtime risks lives, then money should not be a consideration.  A 6500 would probably blow your budget before you populated it, a 4500 may do the same.

A 3560G catalyst switch is a hell of a stable piece of equipment.  We have about 22 cisco switches in service(3524XL, 3550, 3560PS, 3560G, Catalyst 6009).  In the 5 years I have been here, I've power cycled 1 switch one time due to software failure, and it was a documented bug with a documented fix(About 12 of the 22 have been in service more than 5 years).  I've had 0 hardware failures with switches.

Knock on wood.
