EMC NS20 / Switch For Testing / Prototyping 10Gbe Rollout?
Jun 15, 2011We have a 5 node VMWare cluster connected to an EMC NS20 using VMWare over NFS.Right now, our only bottleneck is network and even that is not limiting. We are considering updating our infrastructure and since networking seems to be the the only real issue, they want me to research that first.So I thought I would get a server, throw in a 10Gbe NIC, get a cheapo 10Gbe switch, get some cheapo NAS (or build one) that can do 10Gbe and start testing...Wrong. What a CF 10Gbe still is. At first I just assumed I'd go with 10Gbe over copper. How naive of me. So once I realized that the most "cheapo" 10GBase-T copper switch would run me about $9,000, I shrugged and starting looking at 10Gbe over optics...
IS there a cheapo (relatively) switch out there for someone wanting to test 10Gbe?? Like $5,000 or less?EDIT: BTW, before this goes off-topic into teaming 1Gbe connections being good enough and such, let me say that we are planning for the future here. As I said, we aren't currently limited in any area right now. However, we see that if there was an area we need to focus on, it would be network. So to that end, we'd like to start testing what the future has to offer. We've already tested and are using link aggregation and such at the 1Gbe level.
Cisco Switching/Routing :: SG500X-24 - Good Low Density (~24-port) 1 / 10GbE Switch?
Oct 22, 2012We're looking for Cisco switches with the following attributes to serve as the core switches in a production network:1U (or close), fixed config20 or more 1GbE copper ports4 or more 1/10GbE fiber ports (SFP+)Not ridiculously expensive So far the closest fit we've found for these requirements is the SG500X-24. However, since the SG500X-24 is a "small business" switch we're concerned that the reliability may not be up to the levels of Cisco's enterprise switches, the support level may not be sufficient, the 12MB packet buffer may not be enough to support wire-speed operation (or efficient communication between hosts on 1GbE and 10GbE ports), and so on. But in looking through Cisco's entire current switch line (a daunting task...) this seems to be the switch that best fits the specifications above. So, some more appropriate switch that fits the listed requirements?s why the SG500X-24 would be a poor choice for a production network? Have you had positive experiences with using the SG500X-24 as a mission-critical switch?

To be more specific, would the uplink port on the HP 3800 Switches connect directly to a file server that has the SFP+ card installed?

Jul 6, 2012Im now in charge of a medium/big size network (around 1200 machines).I found some connection pattern that im not shoure if it is correct.I migth be wrong, but i think this kind of connection would cause a continue RSTP change of topology (confusing about the 'direction' of the route to take), so having some latency period (this pattern of connection can be repeated several times in the whole network).BTW, there is no special configuration in switch A for saiyng that port 50 is not being used as a uplink port.
View 5 Replies View RelatedCisco Switches :: SG500-28P Slow Switch Uplink Connectivity
Feb 26, 2013At our office we have a weird performance problem with the following switches and connectivity:
Internet |
SG300-24 (L3) core switch (in our server room)
|SG300-10P (L2) access swtich (in our meeting room) |
SG500-28P (L3) switch (in our meeting room)
We are building a new computer infrastructure that is connected to the the SG500-28P. As you can see above the SG500-28P in our meeting room has an uplink to the SG300-10P in the same meeting room. And again the SG300-10P has and uplink to the SG300-24 in our server room. From the server room, there is connectivity to internet. The network uses a multiple VLAN's and routeing between them. Bootom line is, the internet VLAN ID 10 is tagged to trunk ports and available on the SG500-28P. So client get connected straight into the internet based VLAN.
The performance on the SG500-28P switch itself from VLAN to VLAN is very fast. But... the uplink connection tot the internet and other VLAN's on the core switch are very and very slow! At least 10 times slower than normal. So if I plug a laptop in the SG500-28P and go from uplink to uplink, it is slow! But... when I connect the same laptop to the SG300-10P the connection with only one uplink it is fast. As if three switches is to much. I can't figure out why.

I now have a reason to install with a 1Gb uplink to the Core. I am using a GLC-LH module at each end. I did configure the TE1/1/1 port for the uplink.

Jul 5, 2012I was trying to uplink a switch today on a 1500m run of SMF. I have a 6509 core switch with a 16 port GBIC module. On that end I have a WS-G5486-LX with a 3m SC to LC patch cable.On the other end I have a 3750G with a GLC-LH-SM SFP. I have checked my fiber path and it seems good, (by sight, did not have an OTDR avialable).I can't get the link up at all. Tried swapping Tx Rx at one end, Tried different transceivers. Tried different patch cables. Nothing worked. At about the mid-point of my fiber run the cable passes through another network closet with a core switch for a separate network. If I break my fiber path there and try to connect in either direction it works. The only differences are the length of the fiber run and that the core switch on the other network has a CLC-LX-SM SFP.Is it the distance? Or is there some issue connecting a GLC-LH-SM to a WS-G5486-LX?

When I type the IP in on the web, it accesses the talkswitch phone system.I have set the internal IP to the server as fixed.I have port 21 open for FTP.When I run a test, the internet sees port 21 open. However, I cannot seem to cal lup the server over the internet. Could the talkswitch system somehow be interfereing with the logon?What would the proper syntax be to access the server?

Cisco Switching/Routing :: 3750E - 10Gbe / Slow Read Speed From NAS?
Nov 7, 20129x3750E stacked switch (WS-C3750E-48PD-SF0) (15.0(1)SE2
C3750E-UNIVERSALK9-M)
2x10Gbe uplinks from EMC NAS
At a basic level, we have found that the 10Gbe uplinks have slow read performance with or without a port-channel configured (2-3 minutes for a 700MB file to desktop from the NAS) We switched back to testing a 1Gbe and the read speed is normal. Another anomaly is Win7 / 2008 machines read speed is fine from the NAS while the 10Gbe uplinks are in production?!
Write speed is great on 10Gbe. Only read speed is affected!! the switch is not reporting anything abnormal. We looked at SMB/SMB2 as another possible cause...
mls qos is enabled on the switch but not sure if this is affecting performance.
Is the ANY config that I need to carry out on the interfaces to get the read speed working as it should for both Win7 and WinXP. (MTU is 1500 throughout the enterprise, NAS included).

Cisco LAN :: SA 500 - DMZ Over Single Uplink And Switches
Feb 7, 2013I have an SA 500 with the optional port configured as the DMZ. The LAN ports are running the 192 range and the DMZ is the 172 range.
I have seperate offices (A few hundred feet apart) that have been connected with 2 un managed switches up linked with a single wire. The 192 range stuff runs over this. I need to get the DMZ out to the second room and was asking about how to do this over the single up link and switches. (Trying not to run a second wire)
My lack of understanding had me draw up this diagram attached as a picture, to ask about. What it shows is me trying to get the DMZ through the up linked switches to the other room. I thought of using 2 routers, one on each end. I've been told this is incorrect and wont work.
Maybe a purchase of a second hardware and eliminate the switches? (up link the SA 500 to another device?) What should that device be?
Routers / Switches :: Uplink Ports Used For ISCSI?

Cisco Switching/Routing :: 4510R - SUP V-10GE Uplink
Jan 28, 2013I have a two Cisco 4510R each with two sup V-10GE redundant. The code on these sup modules are 12.2(31r)SG3. I need some assistance in getting this setup worked out. I have all four of the 10GE populated with appropriate optics. I setup a link from one 4510R to the other using these interfaces. From the documentation I found I had to use Tengi1/1 and Tengi2/2 as the redundant pair. I plugged the up link into these ports. The Tengi1/1 (active supervisor) links up and works fine. But when I look at the ports port Tengi2/2 it isn't showing link or active. Now port 2/1 (nothing plugged into it) is showing as active.
Now is the redundancy supposed to be 1/1 and 2/1? If so, the switch is in production, when I move the connection over from 2/2 to 2/1 will it cause a outage? The reason for this is I now have a system with a 10G port and would like to utilize one of the other 10G ports. Is that possible? Or does it have to be a lag/redundant up link to work (say to another switch)?
