We posted a little while ago about upgrades we’ve been working on (infrastructure improvements). We have now completed a second round of upgrades, this time a rebuild of our core infrastructure.
This system is running the latest XenServer and has network IO of 64Gbits/s .
This server farm is homogenous which makes it possible to perform live migrations.
A major change is that we’re now using Juniper equipment and for iSCSI we’re using CISCO catalyst.
We have full power redundancy with 6 power supplies in a blade system which is m1000e and equipped with Intel SSD drives. We took photos before and after so you can get a real sense of how much things have changed.
Green: trunk, black: primary iscsi, red: secondary iscsi, blue: internal, yellow: external
What’s next? We will build one more core cluster and create pool redundancy … so stay tuned 🙂
