Let´s talk about hardware/software. Tintri people don´t tell me what filesystem they use. According to them they invented(?) their own.
But when I watched their presentation with their 3 different appliances. So, what do we have: gigabytes of RAM, some gigabyte of SSD, two SAS controller, some SAS drives. And wow, that SSD drives are used for caching from begin on. Plus kind of plug and play i.e. easy management. NFS... some auto magic copying VMs based on some black boxed algorithm, some nice looking VM performance monitoring...
And of course you can mirror the content of one appliance to the other one. Of course, according to them Tintri is best for VDI, because of IOPS, IOPS, IOPS, ... "You can boot 400 virtual machines within 10 minutes on our boxes. Try this with other vendors", It´s about cost per IOPS and not cost per gigabyte, yada yada yada ...
While listening I thought. Stop, we already have those things: Solaris/FreeBSD and ZFS for equal or less costs with many many many other vendors doing the same thing.
According to HP, A5900 series are top of rack switches
So, no problems with long cables at all...
Price comparison is always a bad idea, isn´t it? So let´s look in one of my main webshops:
1x HP 5900AF-48XGT-4QSFP+ (JG336A) with 48x 10GBase-T, 4x 40GbE QSFP+: 5821,-€
1x HP HP X711 Front to Back Fan Tray(JG552A): 102,-€
2x HP 650W AC power supply (JC680A): 438,-€
1x HP carepack U6P29E: 5 years, next business day exchange, software 2 hours: 2298,-€
of course without VAT
sorry, how could I forget "the optics" ;-)
- 4x HP X140 40G QSFP+ SR4 (JG325A): 3750,-€
"iSCSI can be faster and just as reliable, but then it costs more than FC"
LOL, you don´t work for a company selling fibre channel switches with licensed ports and carepacks for the switch and the licensed ports, don´t you?
Please give me the software features of all your mentioned boxes on an 1 - 2 HU router with 1/10 Gbe ethernet slots...
Will there be a podcast for download afterwards?
- Openflow on a TOR switch? Oh please.
- If I want "cheap" 10GBase-T, I´d go for http://www.netgear.com/landing/10gigabit/
For me, openflow and SDN is not mature enough to get into my core network. MPLS Services with OpenFlow sounds interesting for me. But today there are only some case studies, some testbeds and presentations. Please give me a product number, I want to buy this now!
Talking about HP. I looked at thei release notes ans switches.
1. HP supports openflow 1.0 We are at 1.1, so version 1.2 will be there soon.
2. HP promoted its "A"-series to be put into the core. Well, those switches uses that former H3C OS, whereas the HP 3500/8200/3800 uses Procurve OS. The last-named should be placed on the edge but have openflow onboard. The H3C ones belong to the core, but do not have openflow. Somehow strange...
