Switch crashes

[dvazart]

Hello,

I have an HP ProCurve Switch 1810-24G that crashes every Friday since 30 December.

Our Switch is hosted in a Datacenter in which it has air conditioning and regulated power.

Currently we use it for 3 virtualization servers running OpenVZ with about 100 virtual machines (VPS) over Internet.

Events:
Friday 30 Dec. 18H *CRASHED* - Firmware updated to V.2.2
Friday 6 Dec. 14H *CRASHED* - Enabled options: flow control, Storm control, Auto DoS.
Friday 13 Dec. 18H *CRASHED* - ?

Problem Description:
All Switch ports begin to make flashing lights.
To solve the problem we just have to disconnect and reconnect it.
(I attach a screenshot of the network traffic until time of the crash.)

Anyone have an idea of ​​the cause of these chrash?
May you recommend a reference of an good Switch that fits my needs? (to replace this one)

Thanks in advance!

Have you updated the switch's firmware to the latest version? Have you contacted HP's technical support? FWIW: ProCurve switches come with a lifetime warranty.

BTW: If you're really going to run 100 VM's on three hosts, you should really consider building a redundant network architecture so that, when one segment of the network "crashes", the hosts can use the second segment. FWIW: ProCurve switches are inexpensive and readily available (e.g., eBay).

Just my $0.02,
