Although a chunk of the marketing focuses on it being easier to use for administrators who aren't experts in the full virtualisation/storage/networking stack, I would definitely recommend that anyone buying it for those reasons should probably have a support contract in place for when it goes wrong and they suddenly need an expert in everything to fix it.

Hello, sir, your video is so interesting, I don't know if someone had asked this or no, but if an organization has a data center with HCI configuration and want to have a DRC with 3 tiers arch configuration, is that possible? what's plus and minus from doing it or using same infrastructure as the current data center? thank you before.

Provided the DR solution is compatible with both, then yes; although you'd probably want to at least keep the hypervisor the same on both ends. In terms of downsides... many vendors provide built-in replication options that require the same vendor to be used on both ends, so you may find that you need to use something else - particularly if the storage vendors don't match as many replication methods occur at the storage layer.

I have listened to various videos on this topic and I still have a hard time understanding what these are. I actually work on Cisco Hyper converged as a smart hands. Often the customer complains about how much he hates these devices and how expensive they are. Now I don't get sent to folks whose systems are running, only the customers who are having troubles so I don't have a true sample of how well these do or don't work. Ty for your video I will re-watch this again and maybe again.

Great video, except for one thing. I can tell you as an admin for hyper-converged infrastructure that your negative was Ill-informed. Upgrading storage is surprisingly easy with technologies like CEPH. Networking is where the real headache comes in.. Literally at every level. It was not expensive.. It's just a headache

@salvatorecampolo2032

Жыл бұрын

it's true, but Ceph is designed to handle whole disks on it’s own, and so it handles data object redundancy and multiple parallel writes to disks (OSDs). Hardware RAID controllers are not designed for the Ceph workload, them don’t improve performance or availability and sometimes even reduce performance, at most Host Base Adapter can be used. That's said, It's recommended that you use fast storage SSDs instead of HDDs, and this will greatly increase the overall expense. :-)

@@salvatorecampolo2032 enterprise ssds are an added expense, yes. However, the right tool for the right job. Broadly speaking CEPH for workloads (docker, VMs) AND virtualized zfs NAS solution like truenas scale for long term large storage. Meaning spinning rust still has a place here. For the most part doing that means you can have your cake and eat it too. Providing you use the 3 2 1 rule of backing up your data. Also, I wouldn't use hardware raid anymore. It's dead.

As far as I'm concerned, some announcements like the one that hardware raid is dead, they are just personal interpretations or they are mere propaganda, like those that have been wanting hard drives to die for last decades. After all, if one were to give credit to the various proclamations, following the indications of the maximus expert of Linux, Linus Torvalds, who absolutely advised against the use of ZFS, then those who think like you on ZFS, they would already be out of the game. :-)

iSCSI is slower, because the TCP/IP stack slows it down. And the data must pass via CPU, e.g. CPU is tasked to do I/O where it was offloaded by the DMA controllers of normal SCSI. The SAN works faster and greener when it is built with RDMA (remote direct memory access) devices like Infiniband and the underlying protocol is SRP - SCSI RDMA Protocol

7:05 Same performance - HCI is usually faster due to local reads Same resilience - HCI usually has faster rebuild time with less impact on performance as it is handled in a distributed manner

@ProTechShow

3 жыл бұрын

Saying it's the "same" was a generalisation that there isn't a major performance or resilience compromise by going HCI, but in practice it depends on your design and application requirements. In some scenarios your statements about HCI being faster would be true. In other scenarios a 3-tier infrastructure would outperform HCI. Some examples that spring to mind... Shared storage allows for more drives working together, which means more IOPS. A dedicated storage tier allows for more high-speed RAM caching than HCI where the RAM is primarily allocated to running virtual machines. Most host failures in a 3-tier infrastructure wouldn't actually incur a storage rebuild as compute nodes aren't shared with storage nodes and tend to outnumber them - so the rebuild time is more likely to be zero. IMO it really depends on the application requirements, budget, and design used as to which topology would come out on top in a particular situation.

If we are setting up our own Private Cloud using a software like Cloudstack, which architecture would be best? The Traditional 3 Tier Architecture? Or Hyperconverged? We need to be able to provision VMs and ensure automatic failover to other nodes should any hardware fail at any time. Theres also the cost element but the architecture is more important at this point.

@ProTechShow

Жыл бұрын

There isn't really a single answer to that. It depends on how flexible you need each part to be, how you anticipate each component will need to scale, your mix of skills, financing, etc.

Like the video but I would beg to differ about some of the points regarding linear scaleability. Not all hyper-converged vendors are the same. Some allow non-linear expansion. ie, very compute heavy for VDI say and some storage heavy or even storage only nodes (enough compute for the virtual controller) used for files / object based workloads. Also Hyper-converged solutions are normally based on webscale technology which are designed to fail and have multiple points of resilience and self healing. (full disclosure I work for one such company. )

I heard Nutanix doesn't support/allow hardware after 5 years, is that true?

With NetApp it’s easy to buy extra DS(Disk Storage) when you already have a FAS.

Can you talk about dHCI which claims to solve HCI drawbacks

What exactly is meant by linear and nonlinear when it comes to infrastructure?

@ProTechShow

2 жыл бұрын

In this context it's referring to the way the infrastructure's resources scale in relation to the number of people using it. If you take the example of virtual desktop infrastructure - each virtual desktop would have a set amount CPU, RAM, and storage allocated. If you double the number of people you need to double the number of desktops so you double the amount of CPU, RAM, and storage required from the infrastructure. We'd call that linear, and it's easy to scale with HCI - double the number of people, double the requirements for each resource, so double the number of HCI nodes. Now consider a file server that holds documents. If you were to double the number of people it would probably have little impact initially as the storage tends to grow over time, although it would increase the rate of growth. Chances are the effect on the server's CPU and RAM would be negligible unless it was already struggling. In this case the relationship between the number of people and the resources being consumed is not linear and if you just doubled the number of HCI nodes it wouldn’t match your storage growth and you'd end up with a load of excess CPU and RAM.

I’ve specialised in VMware, but this “hyper converged” infrastructure is truly doing my head in. Too complex. And it’s kind of stupid. Like you said, if I just want to buy more storage, I don’t want the whole damn node - just disks where I can store my data. Sorry, not a fan.

The typical reasons are cost and compliance. Cloud is great for flexibility and if you can refactor applications for cloud-native technology the cost can be reasonable, but most organisations aren't writing their own apps - they're using off-the-shelf ones and if you simply lift & shift them to the cloud it can get very expensive very quickly. Most I come across are running some kind of hybrid mixture at the moment.

Looking like a different hardware model wouldn't change its use in the video and would always become outdated in time. What matters more for the purpose of this video is having a licence that allows me to actually use it in the video.
