Hi all,   to setup a supported version of Ontap Select I've found that there are a set of too much strict hardware prerequisites. But I can understand to avoid poor performance Select instances. But this I don't understand at all:   ONTAP Select is supported on VMware Vsphere Enterprise or Enterprise+ license only. ONTAP Select is a virtual storage appliance and requires certain capabilities from the underlying hypervisor. You would need either Vsphere Enterprise or Enterprise+ license   Why Enterprise or Enterprise+?  Imagine to use a Select on a branch office in my experience I've never met customer using such high license for their small vSphere cluster on a peripheral site.   Why to not let me the choice to install a single node (or a multinode also) version of Select on a simple ESXi free hypervisor? Or on a standard edition of vSphere?   Regards,       ... View more

Hi everybody,   starting from 7.x OCI release in documentation I cannot find any limit to the number of FC ports that can be inventoried. But in "setup" interface on GUI I can read: "License allows 12 ports per TB".   For which I know there's just a capacitive license based on TB raw of storage acquired by the DS a/o RAU. And that's all.   A big customer with thousands of FC ports on the territory and that has reached that limit reported me that they need some "special" license, is it? If license is TB based why there's this limit for FC ports?     Regards,     ... View more

Hi,   assuming that a customer has a ready architecture based on a VMware VSAN datastore (that's a common VMFS datastore). Is it possibile to deploy the OVA of Select on that?   Or does the NetApp software assumes to find a VMFS from a RAID on local disk? My opinion is that it should work, after all (see pic) the vmdk of Select have to stand on a VMFS. In case it works, is it also supported?  Regards,   ... View more

Hi all,   is there something in roadmap that will let use ADP in AFF systems used in a MetroCluster configurations? Thinking to a simple two node 8020 AFF i.e. with 24x3.8 TB SSD it's a real waste to let more that 7 TB (R4 option) of flash to a dedicate root aggregate.   Thanks ... View more

Is there somebody that has knowkedge about «virtual SAN» software that underlies sDOT in ONTAP Select? I don't think that NetApp has written something proprietary and the knowledge of a fine performing technology (i.e. StratoScale, IOScale, Starwind...) could be a strong point. Or maybe is VSAN from VMware? In the FAQ I've read that the RC1 support VMware as hypervisor. What they mean? That I can run VMware on Select or that VMware ESXi is the hypervisor where sDOT runs? Looking at this schema I should think that VSAN is below. ... View more

Coming back to the hardware universe I see that there aren't yet 4 ports adapter in the 10 GbE or the UTA2 families. The only 4 ports available cards are FCP/1 GbE/SAS.   This can  be a very big limit answering to public call for tender where maybe an 8020 is a good choice but they ask for a number of ports that is more than the configurable ones. A lot of storage vendors have on their portfolio expansion cards with 4 ports for 10 GbE or CNA. Is there a plan for NetApp to have these too?   Regards     ... View more

Hi all,   it there a way, an approximate one of course, that let us estimate the contribute of SSD on a FlashPool aggregate? Everywhere I read data that seems to be almost marketing one or the SPM contribute that could be not so easy to read in the real world. Very ofter we have to answer to customer requisite (public trial maybe) asking i.e. 600 IOPS for raw TB or 10 MB/s in sequential workloads...   Are there answers to simple questions like these? (just examples)   A 120 SAS hdd aggregate how much, nominal values of course, how much can increase in IOPS for a 70/30% r/w random workload if cached with a FlashPool? How much flash do you suggest, minimum value, as ratio of SAS/NL-SAS hdds? 10%, 20%...less? More?   Thank you in advance ... View more

Hi,   where I can find cabling schema e/o designs about available FMC MetroCluster in cDOT 8.3? Two nodes and four nodes? The TR3548 used for 7Mode was full of very good designs depicting the real deployment of cable to and from controller and switched. The TR4375 for cDOT instead contains only logical schema.   Regards, ... View more

I've just read the new 3548 TR about Metrocluster and its architecture and I'm quite sure to have well understood that concept. I know fabric metrocluster for in the past I've set up several of them and, every time I was sure that there was a "dark fibre" on the ISL, a dedicated media or something that "come out" from some carrier multimodal line spilled out by a DWDM.   Reading at the recommedations on that TR I have theoretically a confirmation. See image below.   But, several times, it happens that customer declare to have some "FC/IP" line between distant sites, Cisco MDS 9513 and/or MDS 9222i used for other ISL using this "FC/IP" (I know this last one switch is in the MC matrix but I also know that the 4 switches must be dedicated to the MC!). In this case I've often heard that this kind of line can be used for the ISL but at the same time that on those is not native FCP running but Ethernet at 10 Gbps that incapsulate FC frames...  I also know that this kind of line can be used by concurrent synchronous replication mechanisms, such as EMC VPLEX Metro...that uses Ethernet that incapsulates FC or, if any, can use native FC. So, this does not match with NetApp Fabric MC requirements. Is there some detailed document that can explain this? We're not wan communication experts so we can loose ourselves in this kind of analysis. Thank you very much in advance       ... View more
