At this capacity and performance point, even this modest 4-node cluster starts to overlap with traditional dual-controller storage arrays, while providing server on top. We're working on providing better guidance on the importance of queue depths when sizing performance requirements. Thanks in advance for a reply or a link answering thins question! The ratio here I mentioned is physical device number not capacity number. These steps are repeated for the remaining nodes. Over the past week we even got the latest Veeam patch going and backups were processing at twice the speed we had seen on the Equallogic units. Probably not in the very near future, but 10 years ago would you have predicted that more that 60% of all x86 workloads would be virtualized today? You still need to use fault Domain with Stretched Cluster, but simply as a way of grouping hosts on each site together.Next
Thank you again for the open communication. Thank you in advance for your time, if you choose to respond. Lots of documentation coming around this. So I have just not ever come accross it. We will keep you posted on the progress. Now I have a completely different view on Licensing the thing. .
I would strongly encourage you to have a look at this wonderful technology and realise these technical and business benefits for yourself. Oh wow, thanks for following up! We sincerely apologize for this issue. That was until yesterday and the product is now available to download for every customer. Will this one day replace the typical fiber channel shared storage? Management is simplified as well. Only commence work on the next host when you are sure that all objects are fully synced and active.Next
There are a lot of possibilities with these servers if an environment requires it. And it's more flexible to upgrade standard servers than filers. The expert's suggestion was to wait longer, as he believed that things would clear up soon, but wasn't sure what was happening. You definitely need to be careful with this approach. This is to cover the case where we lose the entire rack at Site A. While it might seem a bit confusing at first, you will hopefully see that the intent was to keep licensing as simple as possible while providing flexible, cost-effective options for a wide variety of implementation scenarios.Next
With legacy hardware, when an organization needs more capacity they must buy a new box, shelf or disks, which can be expensive not to mention the time it takes to install it and integrate it with existing architecture. There is also a PoC guide due to be released very soon which will provide you with further detail. It is specified as a percentage of the logical size of the virtual machine disk object. But from what i saw is that: 1. It is 9 days and counting until my evaluation licenses time out. The deduplication and compression overhead is 6.Next
I hear you shout, it is simple open up licensing and just put in your license key and you are away and running. This is again without a node failing in the cluster during these maintenance windows. This gives you a bit more lee-way, in case it take a bit longer to apply the fw and reboot the host. In my case, I used them as the caching tier and had all sorts of issues, even down to Permanent Disk Loss errors randomly appearing, requiring a host reboot. This feature is integrated in vSphere 5.
Maybe need to set up environment and collect some test data. Upgrade is easy, straightforward, and very fast even when upgrading the vSphere build which now only reboots once automatically thus causing less wait and disruption not to mention quick boot. A lot can be said for fiber attached storage via a storage area network, but it comes with a cost and complexity that some companies may not be able to swallow. Every write has to go through the write cache i presume? Martin May 10th, 2017 Hi Jeff, In vsphere essentials only three hosts are supported in vcenter. This makes sense as the hypervisor is increasingly becoming a commodity and the value-add now is in the Cloud Management Software suite that manage the Hypervisor as well as various other Public Cloud platforms. Now there may well be some changes that need to be synced once the host has rebooted. These workloads run in an ever-increasing number of environments: primary data centers, disaster recovery sites, remote offices, call centers, retail stores, commercial ships, and more.Next
There is no feature, capacity or scale limit. Thanks for the kind words on the book — always nice to hear feedback like that. Their guys have been great, and have really come through to try to find the cause of this issue. If administrators choose manual configuration they will have to create disk groups through the disk management tab. Appreciate Cormac, understand the ratio will determine the performance.Next
I love it when things work as planned! So a percentage of the logical size used storage. With an all-flash configuration users can see a 4. After the maintenance is completed the node is placed back into production and the administrator immediately moves onto the next node in the cluster to be patched. You might say that is not unexpected, but think about this for a minute and consider the implication. So we had done a lot of work over the 60 day evaluation period, and now we are facing the very possible action of having to redo it all. Are you using them as the caching tier or as the capacity drives? These statements are meant to reflect the same thing Stevin. I would have expected a more joined up licensing policy.
You need to wait for this to complete before starting maintenance on the next host. All may testing, Playing and enterprise experiance is with the Enterprise Plus level. A quick summary of the key changes are explained below. Now you may only use a portion of this, e. I slept much better knowing that I wouldn't have to worry about a controller fail-over causing an outage, or dying disks not being reported and eventually causing the unit to fail catastrophically as we had seen with one of other Equallogic units which luckily was used only as a replication target as it was out of warranty. This should be well documented in the stretched cluster guide. I understand this is not the preferred way of doing maintenance, but I was just curious what could happen and if there were any fail-safes when this occurs.Next
