Posted by on January 27, 2015 Now that we have all virtualized our compute processor and memory resources in the data center, the next logical step is storage. See below the storage performance stats during the provisioning cloning from template time. We will keep you posted on the progress. The ratio here I mentioned is physical device number not capacity number. Management is simplified as well. This is true, if you are using Enterprise Plus Licensing, however what happens if you are not using Enterprise Plus licensing? Since it is difficult to state which is the best for every customer, we have used a 10% rule-of-thumb to cover most virtualized application workloads.
The expert's suggestion was to wait longer, as he believed that things would clear up soon, but wasn't sure what was happening. Thanks for the kind words on the book — always nice to hear feedback like that. All may testing, Playing and enterprise experiance is with the Enterprise Plus level. That was until yesterday and the product is now available to download for every customer. 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. 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. You might say that is not unexpected, but think about this for a minute and consider the implication.
You need to wait for this to complete before starting maintenance on the next host. 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. We are also investigating options to provide better status visibility during rebuild operations. 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. Hope this information helps and please feel free to reach out to me through email if the issue is still pending. Now you may only use a portion of this, e.
At least three of the hosts need to have disk groups created. Is that the normal phenomenon after enable the feature? The transfer rate drops to zero for up to 7 seconds for periods during the transfer. Imagine what the performance would have been if this was on enterprise grade hardware in your datacentre? With an all-flash configuration users can see a 4. There are a lot of possibilities with these servers if an environment requires it. Are you using them as the caching tier or as the capacity drives? Thanks in advance for a reply or a link answering thins question! Its almost like its cache allocation has filled up and its waiting for destage to complete. A quick summary of the key changes are explained below. The deduplication and compression overhead is 6.
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. And it's more flexible to upgrade standard servers than filers. There is also a PoC guide due to be released very soon which will provide you with further detail. We're working on providing better guidance on the importance of queue depths when sizing performance requirements. 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.
Every write has to go through the write cache i presume? It is 9 days and counting until my evaluation licenses time out. This should be well documented in the stretched cluster guide. At 10:30am, all hell broke loose. 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. I explained that their own web site clearly stated differently. We sincerely apologize for this issue.
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. The path vendors take to achieve these quad-objectives is widely varied however. Thank you in advance for your time, if you choose to respond. And user configure it with their application case. You still need to use fault Domain with Stretched Cluster, but simply as a way of grouping hosts on each site together. Since the outage, we have had no issues.
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. Can you help me sort that out? Thanks again to everyone who posted and messaged me with advice and guidance. Is there a second swap object for it? Now I have a completely different view on Licensing the thing. This is again without a node failing in the cluster during these maintenance windows. So a percentage of the logical size used storage. Will definitely go for the 710 if I go that route.
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. I love it when things work as planned! Their guys have been great, and have really come through to try to find the cause of this issue. So I have just not ever come accross it. These statements are meant to reflect the same thing Stevin. I would strongly encourage you to have a look at this wonderful technology and realise these technical and business benefits for yourself.
