Hi folks, Do you guys have ever think about the question. I read some guides and confused now. 1) node memory number: It seems every type of node has different supported memory number configuration: For NX-1064-G4, It shows only support 16x dimm ! What happens if I install any number， i.g 1, 2, 3,4,5,6 or any number 2) node memory installed slot location: It also says there`s an fixed slot order for different number dimm scenario. what happens if I install dimm not according to the guide ? 3) memory type: LR or R DIMM it also says there`s two type dimm, How to confirm which type is supported by specific type of node ? P.S my environment I have a node NX-1065-G4 with default 64g(4x16g installed in 1a,1b,1e,1f) and now I add two additional 16g dimm into slot 1g,1h. It work fine till now. but my memory number confuration is not supported by the guide ! the guide says NX-1065-G4 only support full slot (16x) dimm configuration ! so the guide has no tips about the slot order too while numb
Hello everyone, my environment: 6 * 3060-G4 NODE per node : 2*ssd 480G， 4* HDD（how to find out if it`s sas or sata drive ?）1TB RF=2 --------------------------------------------------------------------------------------------------------- how to calculate? I see prism report 22.18TiB MaxCapacity(Physical)。but I think physical should be 1T*4*6+480G*2*6=24T+5760G if RF2 need two complete copy(like RAID1) ?, the usable capacity is just half of 24T+5760G, and if after one node failure, for N+1 , I should also reserve another extra node capacity(4T+480G*2) ? also I have a basic question and guess, if I have three NODE in all(assume not 6 node ), and one node failed, lost data will be replicate to another any node of remaining two, because of RF. so I have two copy again. but if the second node also fails later(now I have only one node), will the cluster be down ? data lost ? I think data shouldn`t be lost because one of the two copy exists(3 node ,2copy-> 2 node 2copy-> 1node 1copy)
Hello, I`m not new to nutanix, but have a long time not focusing on nutanix installation step. while I installed nutanix with foundation+Phonex(NOS location selection)+Hypervisor image one year ago, I think Phonix is just exactly NOS at that time. I find it seems to have new method to image node: Foundation+AOS(NOS location selection)+Hypervisor image, or even having an JAVA applete+Foundation+AOS(NOS location selection)+Hypervisor image I`d like to confirm detailed difference between NOS , AOS, and Phoenix. I have asked guys, no one can explain this clearly to me. also what make me confused is there are varous statement about it in different guide(it is self-contradictory) , also Which phonex package should I use ? shows you need manually make/generate phonix ISO with AOS , but sees you shoud use the Phonix ISO downloaded from nutanix portal site ! look at these slices : "Phoenix is a tool used to install the Nutanix Controller VM and provision a hypervisor on a new or rep
Hello Folks, I`m busy installing a 6 node cluster, some errors or doubt comes out along. my environment : 3 block, 6 nodes (2 nodes/block) AOS 4.6.2 一. When I create a new container, make the Enable Erasure coding button checked, error pops up"enable EC-X will break the current block awareness !" seems mean ECX will disable block level awareness ? 二. As many of us know, if need locate the physical slot location of a disk, you can simply led on that drive. but there is possibility led on function inaccurate or disabled, in this scenario, you must locate the disk by disk id rule, e.g shelf id.slot/bay ID, but the DISK ID in prism hardware section seems ramdom/ruleless number, I can`t locate physical location for a disk. 三. When I do the test about removing a node from nutanix cluster, A doubt appears: Do I need or is it the best practice to execute storage vmotion(other then only vmotion vm`s ) before removing the node ? I think the diffecrence of two methods is who is the data mov
Hello friends, 1）Have somebody upgraded hypervisor(ESXI specially) using prism successfully ? can share some key steps or caution about it ? Because I have no test equipment on hand to verify this. 2）if using prism, and encounter ESXI update failure, Will Nutanix support for ESXI problem ? 3) can upgrade be done via VUM/ESX-CLI（traditional method）only without PRISM ? thanks.
Hi Folks, For Nutanix product, Is it a best practice to have the latest software version (e.g AOS,NCC) installed, No matter first-time installation, or upgrade. Some venders may advise just install the slightly lower version then the newest. My real user case: we installed NX 2 months ago, and plan to put it into produciton these days, but two new AOS version has been available on Portal.nutanix.com, So Can I update AOS to the newest one ?
Hello Folks, NX-1065 has only two 10G port, and two 1G port. and I have only one pair of 10G switch, and one pair of 1G switch. In my opinion, I`d like to make ESXI port(mgmt, vmotion,nfs vmkernel), and CVM port(prism mgmt, cluster mirror ) run on 10G switch, and configure 10g switch uplink to other network which I can connect to ESXI MGMT and prism. make vm data port connect to separate 1g vswitch. but network guy told me the 10g switch can`t uplink to externel network, so I`d like to know Can I move the ESXI port (mgmt) and CVM mgmt(VIP) to 1G vswtich， and create addtional vmotion,nfs kernel port connected to 10G vswtich, also leave CVM cluster mirror interface connected to 10G vswtich. networking design is the key things.
Hi Folks, I`m installing a new also my first AHV(latest version installer-el6.nutanix.20160601.20,with latest AOS4.7.1). I`m new to KVM,as well as AHV. So some problems met, tough time these days. Any help would be highly appreciated, thanks in advance. 4) centos 4.7 guest vm also the guide 《AMF_Guide-AOS_v4_7》 says only support CentOS 6.4, 6.5, 6.6, 7.0, 7.1, 7.2 Is there a support matrix for all the vm guest type ? 7) kvm vm mgmt via Prism there`s too little function for manaing ahv hypervisor and guest vm via prism(it seems only basic vm life-cycle mgmt). Can I add usb device, make an ovf template like vmware vcenter ? I`m not such familiar with virsh, ovs cli tool
Hi guys， two basic questions: 1)can cvm cluster and ESXI data use the same 10g switch with no performance penelty ? (I have only one pair of 10g switch, and NX1065 one dual port card. As we know, cvm cluster must use 10g network, but I`d like also to use 10g for ESXI data network. ) 2) generally ESXI mgmt(usually,vmkernel port for NFS access) is on the same 10g link with cvm cluster(also CVM prism mgmt), If the user`d like to have a separate uplink or subnet for ESXI MGMT, is it ok ? I`m worried about the performance problem. thanks in advance !
Hi everyone, I imaged a nutanix cluster these days, and found strange phenomena. I found many error key words in foundation node log, but imaging showed successful finally. I clicked "retry imaging failed nodes with last config" many times, after some node failed, and it succeed. I`d like to know why it failed and succeed after just retry. also the foundation process tab showed 3 node failed at 78%, and the node log showed it`s finished ! and after retry, it`s 100%. I`m very worried about if it`s truly successful and there`s potential risks. p.s my environment: Foundation 3.1.1, AOS 4.6.1, ESXI5.5U3D，NX-1065-G4
Dears, I found I can`t find ESXI 6.0U2 and AOS184.108.40.206 release in Nutanix compatibility online tool. but I can find ESXI6.0U2 in the iso whitelist json. So It make me confused Which release exactly can be supported by nutanix ？ Finally, I install ESXI6.0U2 and AOS4.6.1. I·m not sure if Compatibility tool is just a best practise or not up to date timely. Can I simply always install newest ESXI version and NOS ?
