STP With Procurve 2650
Jun 12, 2008Is there anyone configuring Procurve 2650 with Spanning Tree Protocol? I want to have redundant up links to different router ports, but whenever enable STP, it seems lead to loss packets too much

Dec 19, 2007I am going to setup new clustering system with 2 Procurve 2650. One of public access and one for private connections (most for database access, control panel connections, backup files transfering). Aiming using around 35-38 servers. All servers using SM board with 2x gigabit NICs
Is there any trouble I can face to with that kind of network? Or any better solution with the same budget? or should I use gigabit switch for private connection?
Poweredge 2650 Linux
Jul 23, 2008Who has linux on a dell poweredge 2650. i have debian on mine right now but havent been able to get the raid and embedded management and MIB's support working with linux
considering switching to redhat so i can use the packaged software from dell.
any one have any advise or experience getting the embedded hardware working with debian? if so how did you do it.
i want to be able to monitor the raid and the drives for defunt drives and such, and also be able to get into the embedded management card, and to be able to use mrtg with the MIB's for fan speed, cpu temp etc etc
Colocation Of A Dell Poweredge 2650
Aug 10, 2009I have a Dell Poweredge 2650
Specs:
Dual Xeon 2.4 GHz 400 MHz FSB
ServerWorks GC-LE Chipset supports five PCI buses: three PCI-X (1 x 64bit/133MHz,
2 x 64bit/100MHz), one 64bit/66MHz, one legacy bus (32bit/33MHz)
12 GB DDR PC 2700 ECC Registered
(X5) Maxtor Atlas 15k II 3.5 series Ultra320 SCA II 80 pin in RAID 5
PERC 3/DI RAID controller with 128MB or Cache with back-up battery
(X2) integrated Broadcom Gigabit BaseT with load balancing and failover support
INTEL PRO/1000 MF GIGABIT SERVER ADAPTER C2126 FIBER
J1679 DELL INTEL PRO1000MT DUAL CARD PCI-X
Dual 500 watt power-supplies
I have a few questions.
1) How many websites could a server like this handle on a 100 Mbps synchronous line?
2) Are there any colocation companies that would hook up to the fiber card for connection?
3) What is the best choice of action when dropping line to in in a colocation center? The dual on-board or the Dual Intel Pro/1000MT? I know that there is load balancing on the on-board Broadcom NICs but how do you use them for load balancing mode?? Then are seen as two separate NICs. I can drop as many lines as needed in the data center I am planing going into so number of lines is not an issue. let me know the best action on connectivity for my server with my specs provided.

SATA Drives For A Dell Poweredge 2650
Jul 24, 2008Is there any way to use SATA harddrives instead of SCSI harddrives with a Dell Poweredge 2650? I purchased the Dell on the cheap. It came with one 36GB SCSI drive. Four more hotswap slots. No sleds/caddies/trays for additional drives, so I need those as well.
Looking at the market (eBay mainly) for used SCSI harddrives, it's pretty pricey to get drives of a decent size (73gb+, $50+ each). I would like to use SATA drives instead (get them brand new vs. used SCSI). Problem is this server does not have an embedded SATA controller, just the SCSI Perc3/DI controller. So maybe get a 3ware 8000 series SATA controller + sata drives + trays? Is that possible? There are no molex connectors inside the server. Power to the harddrives comes from the SCSI backplane.
The server will be just for my personal stuff (personal web site, DNS, etc), nothing mission critical. Just trying to save a few bucks buying cheap large capacity SATA drives vs. used smaller capacity SCSI drives.
Addressing VLANs On Extreme Summit 48
Feb 13, 2007Having a slight problem working with one of our Extreme Summit 48 (ugh) switches - I've figured out most of the basics, but I can't seem to find any way to add a secondary IP address to a VLAN! This, I would have thought, would be a pretty basic feature to have. Typing "config vlan [vlanname] ipaddress 1.2.3.4/24" works for setting the primary IP, but I can't figure out how to add any more - and doing the command again just overwrites the first one.
So... does anyone have any tricks up their sleeve, or is this something that Extreme neglected to add to this model switch?
Opinions On Extreme Networks Switches
Mar 5, 2007I had the chance to work with the summit24 switches, and I personally liked them. It is straight-forward in my opinion for the Web Interface compared to others I have seen and the pricing seems to be reasonable.
I was wondering if anyone has had any experience with any of their switching devices.

Apache :: Web Server - Extreme Laggy Pages
Nov 21, 2013I work for a company with a highly trafficked site (about 100,000 unique daily visitors). We have our "MANAGED" hosting through Rackspace for quite the pretty penny per month. It includes a dedicated back end / DB server and cloud servers for the front end.
The setup has been functioning perfect for 10 months now; but this past Monday the speed of the site immediately dropped. Page load times fell from 1-2 seconds to between 10-20 seconds, and sometimes not at all. As far as we know (and as far as Rackspace says), no server setting were modified. No new code was introduced on our end. It's a mainly static site, with minimal user interaction with the backend at all.
We've monitored the traffic, checked IPs, etc. We've even tunes down several site features in the interest of reducing server load. Upon a server reboot, the active threads/processes running on it IMMEDIATELY jump back up to maxed out levels. It seems like once our daily traffic reaches 10MB/s, a type of queue forms and the delays begin. Rackspace assures us that we're not limited to that.
Versions:
OS: cent OS on cloud
OS: Redhat on Dedicated Server
Apache: 2.2
PHP: 5.3 / MySQL: 5.1.69
Some more background info: The site is typically busiest from 7am until 3pm EST. For the past few days, we've noticed that between 7am and 9-10pm the server has just lagged incredibly. However, at around that 9-10pm mark, something changes and the pages go back to loading almost instantly. (There is still decent traffic though.) Then at around 7am again it slows to a crawl.
Rackspace has offered solutions such as spinning up another server and incorporating their load balancing - they are in the process of this BUT they do NOT think the traffic is the issue. At one point they actually said there was potential packet loss somewhere in the network, but no progress has been made.
HP Procurve
Jul 27, 2009with a mini-hp VLAN problem I'm having. I currently have a HP 2626 that a local client had lying around, but I'm having issues understanding the VLAN setup.
What he wants to do is to setup 12 servers off the HP 2626 and use the routing & VLAN support. I was wondering what options are used in the VLAN config to get this to work, as well as how to route additional IPs that may be used later on to VLANs. My cisco training tells me to use Trunk ports, but I don't think HP uses that terminology.
Procurve Vs Catalyst
May 7, 2009We are currently looking making some switch changes in our rack as we are expanding.
We don't push a whole lot of traffic (currently 15MBPS) but would like to think ahead for growth.
We are looking at using either the Procurve 1800-24G which will provide web managed 24 10/100/1000 ports or the Cisco Catalyst Express 520-24TT which provide web managed 22 10/100 & 2 10/100/1000 Ports.
Connected to these switch would be our servers and then uplink to our firewalls.
HP is cheaper and provides faster ports, but would Cisco provide additional value over the HP because it's Cisco and their experienced technology?
HP Procurve 2610
Oct 13, 2009I have been really trying to learn all I can about layer-3 switches and have gotten good advice on my other post. I've never had to use them before, and in moving to a new datacenter network I'd like to take advantage of dual feeds that require a layer-3 switch.
I've been looking at switches that are across a broad spectrum of prices, between $500 and $2500 or so. I'm 95% decided on the HP procurve 2610 since we don't push a lot of traffic (under 5mbps) and I don't need anything too fancy. I considered a Cisco 3560 and 3750, as well as Juniper... but for this thread I'm really interested in hearing about any experiences with the hp 2610?
Essentially, two feeds from my DC will go into one VLAN, which will act as the gateway for a second VLAN, which has about 7 servers attached to it.
Since the layer-3 switch will be routing all traffic from one VLAN (7 servers) to the second VLAN (dual DC feeds), I'm curious to know if anyone has any experience with the hp 2610.
I don't need to give each server its own VLAN. Right now they are all under our own control, so they can all share the same VLAN. So one big VLAN for our servers routing to one tiny VLAN for the two uplinks is all I need.
SFP's For Hp Procurve 2810-24g
Oct 8, 2007I know a lot of people here on the boards have a good amount of experience with the HP switches. I am going to be ordering a 2810-24g this week and will need a 1000BaseSX sfp to throw in it. Are the HP's brand specific? IE do I absolutely need to purchase an HP sfp and not say, a foundry or cisco one? I need to figure out which one I will be ordering, hopefully one I can source locally quickly, so that I know if its connecting via lc or sc and make the call for the cross connect. I am in the bay area, maybe someone will know where I could pick one up too.

Oct 11, 2009I've been reading and searching on here as much as I can to try to help me in making a decision, unfortunately when I think I know what to do, I read something else and get confused again.
We are in the process of moving networks within our datacenter and will have 2 drops coming into our half-cabinet. We have about 7 servers in there, some for our own use and some for clients. In all cases, we manage the servers and are the only ones with root access (no need for VLANs for the purpose of protecting IPs etc).
We currently have a single drop and use an HP procurve 2524 layer2 switch that has been in there for over 6 years and never had a single hiccup. We also don't push much traffic at all though. Under 5mbps combined.
My question though is this: moving to the new network we will have 2 drops that are set up as HSRP on their end (upstream of me, I don't have to worry about having two switches). In order to use the dual feeds, we will need a Layer3 switch. One feed will be active, the other is not, both are connected to the switch via a VLAN and provide a gateway for VLAN2 to use. I have never used a layer3 switch, though I'm not *too* concerned since I don't expect we'll be doing anything too complex. My understanding is that one VLAN (VLAN1) will be set up with an IP address assigned to each drop and that VLAN1 will create a gateway for VLAN2. The second VLAN (VLAN2) will be all our "inside" client IPs that will then route through VLAN1.
I was briefly checking out the cisco 3750, but I think it's overkill...? I don't want to spend too much money, since I don't think we need any complex setups, at the same time, I don't want to waste money by buying something that won't work efficiently down the road.
My immediate short-list is now an HP procurve 2610, an HP procurve 3500 J9470A (not the YL), and a Cisco 3560 24-TS.
Of course, then someone mentioned Juniper (whom I have zero experience with either) and hence the title to my thread... I'm thoroughly confused. I was looking at the EX3200-24T.
Ok, so if I have to boil this down to some simple requirements/thoughts... here goes:
1. I only need 24 ports for now.
2. I use SNMP currently to monitor usage for clients (and overall)
3. I like HPs and have used them for layer2, I like their lifetime warranty and software availability
4. I don't have direct experience with Cisco at all.
5. Aside from routing from one VLAN (provider side) to another VLAN (my side), I don't think I need any other special features (hence the hp 2610 being ok I think, since it offers "lite layer3")
6. Some people say HP is great for layer2 but not for layer3? Now I dont' know what to think.
7. Currently use about 2mbps and might jump to 3 or 4mbps, but don't have major needs. I'd like for this switch to be able to last me a while though... so maybe 20~40mbps+? (but still not the hundreds of mbps that others here push
8. If possible, I'd LIKE to limit some servers to 1mbps or 2mbps on a per-port basis... but this is not a hard requirement. (I think this takes the 2610 out).
Budget: I like the $500 price tag of the 2610, but can spend the $1500~$2000 for the HP 3500, Cisco 3560, or Juniper. I would just rather not, if the price/features are not justifiable.
Hopefully I've provided enough information for someone to offer their insight? I think a few strategic key points or questions from someone with more experience might be what I need to help me bust through the "too many choices" fog and end up with the best switch for my situation...
Procurve 2848 Price
Dec 28, 2007I am looking for a Procurve 2848 switch. It's listed on ebay with different prices (from 650 to 3000usd). I wonder what price I should consider as a fair price? Dont want to pay much, but dont want to buy broken unit at cheap price either. An used one is fine whenever it's still working at all ports

View 7 Replies View RelatedProCurve 2626 Console Access
Jan 21, 2008What type of cable/settings are needed to access the console port of a ProCurve 2626 J4900A? the recent one I ordered wasnt working with the regular way I access these switches.
I use a null modem (crossover) female-female serial console cable and connect it to my laptop serial port w/9600-8-1-None to access my ProCurve 2900 48G series.
But I tried using a straight/null/rollover(cisco's) and none of them worked. I also tried 9800-8-1-xoff/xon. All of them are giving me weird text when I press [ENTER] numerous times. I can access my 2900 series switches fine, no problem, just these 2626 ones I cant. My laptop can definitely detect the port cause when I disable it, I get a message on my terminal window which says "disconnected". So I am messing up somewhere.
By the way, I actually returned the switch when it came the first time because I thought they gave me a faulty one and I got another one, but it behaves the same way. But the actual switch functionality has no issues as I can assign my servers IPs and be able to access them remotely. I just cant configure the switch itself without the console port.
Procurve 2810 Versus 2848?
Sep 1, 2007I'm having a tough time finding a discernible difference between the 2810 and the 2848, beyond the $1k price premium on the 2848. Can anybody speak to the benefits of the 2848 over the 2810?
View 5 Replies View RelatedProcurve 2800 Vs. 2600 ~ Public Vs. Private
Dec 14, 2007The only main difference I see between 2848 (48 ports) and 2650 (48 ports) is the vast difference in thoroughput and switching capacity, 2848 (Throughput: Up to 69.8 mpps; Switching capacity: 96 Gbps) having a higher capacity and 2650 (Throughput: 10.1 million pps; Routing/switching capacity: 13.6 Gbps).
So now, if there is a public switch for http/ftp/ssh and private switch for backups and there are about 35 servers connected to each switch, does it make sense if I go with 2800 for the private switch and 2600 for the public?
The basis of my conclusion is that on a public port with limited bandwidth, a user cannot continuously push close to 100mbps for long before running out of bandwidth. But on a private switch where the user has unlimited bandwidth and can push 100mbps continuously for longer periods and some of the users on the private switch might also have 1gbps port access.
Web Managed Procurve Sufficient For Important Edge Switch
Jul 3, 2007I've been tasked with buying a "good" edge switch for my company's datacenter presence. After a full day of searching around and reading, I think I have decided on a procurve. The question now is what is sufficient for our needs.
We currently have 8 machines and will possibly add another 3 or 4 before the end of the year. We're running gigabit everywhere at the moment, and at bare minimum would need gigabit to 3 of our servers currently. Hopefully we will need gigabit to 4 or 5 servers by the end of the year.
Our website is of very high value to us, but we're also very much in the startup mentality of pinching pennies.
My question is if a web managed switch like the procurve 1800-24g has some performance/reliability downsides compared to like a 2810-24g managed switch. Looks like the 1800-24g can be had for about $400, and the 2810-24g for about $1300.
Searching around this forum, I saw a few references to the 1800-24g where the comment was that it would be great for a lower throughput need. Can anyone tell me why this would be insufficient for higher demands?
Our peak sustained throughput on the uplink to the hosting provider's router so far has been about 120mbps, and we hope to double this by end of year (and grow beyond).
If possible, I would like to be forward looking to the point where we will want to spend more money and have redundant switches in place to protect uptime. I do see that the 2810-24g is listed as stackable, but reading /rnd/pdfs/ProCurve_Stacking_Technology.pdf on HP's website (newbie not allowed to link in posts) seems to me to say that I wouldn't have any options for automatic failover to a slave switch with it. Does anyone know if this is correct?
Having a failover hot switch ready is not a deal breaker since we're only looking at switches that will give us high confidence in the first place.
How about comments on the wisdom of buying something like this used? My gut instinct is that I should avoid used since this is a high performance single point of failure for our entire internet presence. But I don't know how rock solid I should expect a used procurve to be.
In case you are wondering, our technical needs from the switch our modest. I will probably set up a vlan for each of our load balancing clusters to contain multicasting, but the only other feature I know of so far that I desire is the snmp reporting data.
I guess the root question is - would a web managed procurve leave me at a disadvantage for row performance or reliability compared to a full managed procurve?
