[AusNOG] Cheapest half decent 10Gbps switch (for iSCSI only)

I'm not that familiar with vSphere as we don't use it for exactly those reasons (dear as po$ion).  But couldn't you configure MLAG on the Arista then use a bonding mode other than LACP on the ESXi hosts?

I can vouch for the Arista, we have them running in the core @ one of our clients, running multiple 10Gb LACP trunks (NFS not iSCSI) against a NetApp 3250 backend, and they don't miss a beat.. Mind you if you are using VMware and want to utilize LACP you must have Enterprise PLUS vSphere licenses which cost as much as a house block (nearly).

As per the Cumulus Linux and The Register you'll note that all three switches share the Broadcom "Trident+" merchant silicon.  The only difference is the Network OS.  In the case of Cumulus Linux its been around quite a while now so should be mature.

Tell us about your packet buffers.    

  

I'd (and we'd) actually like to know.

I can give you pricing and info on some Huawei switching options if you like (disclose: we are a disty). Nothing down near the netgear stuff however, but you'd be looking at 24x10GE @ wire speed well under half the cost of the cisco/juniper options you've mentioned. Contact me off list if you are interested.

Hi Guys,   

  

Not sure if this is the correct place to ask this question, so apologies in advance - but since most people here run high speed storage networks it is probably relevant. 

  

Can I have some recommendations for low end, cost effective, 10Gbps switches (for iSCSI use)? 

  

Only need around 8-10 ports per switch, and all the switches I'm looking at from the likes of Cisco and Juniper are around $20k-$30k a switch - seems pretty extreme really. I'm looking at deploying 2 x 10Gbps iSCSI switches for a client for a small VMware project, and am looking for suitable switches. 

  

Looking for suggestions for a half decent switch to use here - doesn't have to be top of the line with heaps of features, just something very basic, as long as it's 10Gbps and has at least 8 ports. 

  

Looking at the Netgear XS712T, these are around the $2k mark, which is in the ballpark of what I need. Looked at the Netgear XSM7224 and DELL N4032, but these are around the $5k mark per switch (but granted 24 ports with dual power supplies) 

  

Suggestions anyone? 

  

Thanks 

  

James
