Dell EMC's all-flash Isilon how to understand, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

In other words, EMC's Scale-out NAS Isilon is still very strong, although the growth momentum is not as good as XtremIO, but it is also very good. Although it is surpassed by Huawei's OceanStor 9000 in China, it is still absolutely the first in the world.

EMC has always used Isilon as the main product of Data Lake, and now EMC has packaged a concept called Data Lake 2.0. Compared to 1.0, it extends to edge and cloud support.

All-flash memory is very popular now. EMC defines 2016 as the year of flash memory, and the main support is that in 2016, the unit capacity cost of 15K high-speed HDD is basically the same as that of SSD. In fact, Huawei announced as early as 2015 in Flash Storm that 15K SAS disks could be replaced with SSD with equal capacity.

Although EMC XtremIO sells well now, it is also the number one AFA in the world. However, XtremIO is only SAN (it is said that NAS will be supported soon), and 80% of the data center is unstructured data, which can be stored on SAN, but it is a more natural choice to keep it on NAS, because this is a collaborative era, and sharing is a natural requirement.

Pure Storage, EMC's arch-rival, also saw this trend, releasing Scale-out NAS FlashBlade with all-flash memory ahead of time. As soon as EMC saw that he was lagging behind, he hurriedly said to the outside world, I also have such a product, that is, to develop something codenamed NITRO.

And, just last month on DELL EMC WORLD 2016, the product was hastily released, called ISILON ALL-FLASH. Onlookers asked that this product will be GA in mid-2017, and it will be more than half a year before it will be officially available.

With this thing, Isilon's product line is more complete.

The all-flash Isilon actually has only one hardware form, a 4U chassis with four nodes in it. Each node supports 15 SSD disks. The capacity of the disk can be selected, including 1.6TB, 3.2TB and 15.4TB.

The interconnect interface of the node must be IB or 400000 megabytes, which can be expanded to a maximum of 100 chassis, or 400 nodes.

The capacity can be supported to 100PB.

It is understood that the CPU of each node is 1 Broadwell-EP Xeon, supports 4 DDR4 DIMMs, and one chassis supports maximum 1TB RAM.

The new all-flash Isilon does not use NVRAM to keep logs, but directly uses flash memory, which is, of course, protected by images. The advantage of this is that general-purpose industrial components can be used.

After the Isilon all-flash node comes out, the original high-performance node S210 will continue to be sold. EMC says its IOPS is six times that of S210, while its aggregate bandwidth is eight times higher.

The key point, all-flash Isilon is the same as before, using the same unified software, that is, OneFS. Currently, the latest version of OneFS is 8.0.1, but this version does not support new all-flash nodes. EMC will release a new version to support it.

In other words, all-flash Isilon will inherit all the features of the original OneFS and can be integrated into the cluster of the original Islion system. In this way, we can use a hierarchical approach to take the all-flash node as the highest performance layer, which is higher than the original S210 performance. However, as we all know, Isilon only supports IB and 10GE for node interconnection, but all-flash nodes support 40GE and IB. In other words, only when the original Isilon uses IB for internal interconnection, can all-flash nodes be added to the cluster, which limits many scenarios that need to be upgraded. After all, the deployment should use more 10 gigabytes than IB.

Therefore, onlookers believe that all-flash Isilon mainly promotes new scenes, especially in electronic design automation, media high-definition editing, life science research and big data real-time analysis.

Because all-flash Isilon inherits all the enterprise features of OneFS, it is certainly much better in terms of features than Pure's new product, FlashBlade. From a comparative point of view, Pure has only one advantage of compression, and the others are not as good as Isilon.

Pure's FlashBlade doesn't have GA yet, but it should be faster than Isilon All-Flash, that is, at the end of this year or early next year. It seems that the battle for all-flash memory has gone from SAN to NAS. It is said that Huawei will also launch an all-flash OceanStor 9000 next year, which may also be called an all-flash FusionStorage 6.0. As Pure basically does not enter the Chinese market, therefore, the domestic all-flash scale-out NAS, it may be more EMC and Huawei in the competition.
