VSP design is a tightly coupled two controller fully active-active design with communication between the two controllers being over PCIe.
See here for more detail. Note that you can filter for Host Already connected, but if you choose from hosts that are already connected you will remove the host from the current Storage Group and move it to the new one really, really dangerous idea, if you are not aware of that!
VSA — this is a virtual appliance. This interconnect must be very fast, high bandwidth with low latency. Are the block snaps finally without a huge write performance impact?
Even then, if excessive disks are lost it is possible that production data could be lost as well, requiring some form of recovery. But are they offering something materially closer to a unified architecture?
Anything beyond 4-way multiplexing on tape is not. It would fall into the traditional dual controller storage array category, and is an improvement on the existing VNX line. EMC shares user data and metadata on the same cache boards over the same interconnects.
Again, the Intel drives were able to maintain significantly lower latency than the PRO throughout the majority of this test, starting at Know what your boxes can push. What is the point of this? Click the Synchronization tab, and then click Filter.
It can also provide a surprising new twist: One initiator might be only in one Storage Group. It could make sense to use low end commodity hardware out in your DR site, maybe even just a single physical server and send your data to the VSA.
Some areas of NetApp leadership to answer a question in the comments: Too much and restores take forever. Object-based systems started shipping roughly fifteen years ago and perhaps the most remarkable characteristics of these types of systems were the extensive use of cryptography from the application layer down to the storage system.
Moving to sequential performance, we looked at our 64K benchmarks. This means doubling up on hardware, and double the hardware equals double the cost.
And as they are not as tightly aligned to Intel will they always be behind EMC in the exploitation of the Intel advances — how much coding on VSP will have to change when we see the likes of Sandy Bridge and Ivy Bridge processors arrive with their new memory controller architecture etc?
User error can also cause data loss if an operating system user removes database files with a command such as rm. Cabinets filled with disk drives and increasingly large amounts of raw block data flowed onto these systems.
Or is yet another, completely separate system Isilon needed to do that?
For example, a copy of a video stored in Los Angeles could be checksummed, encrypted, and stored in four different locations around the world.When a storage system provides new trust features, it is not uncommon for these features to perform quite poorly.
In a previous post, I looked back at the earlys introduction of RAID-5 as a new trust billsimas.comming a write to a RAID-5 storage system required four disk operations.
Dec 17, · *The software is the same across all machines. **The disks sited are those which host my Outlook OST (I am the Exchange Storage Program Manager; I have lots of disks in all of my computers).
HP needs weeks to ship additional TouchPads, according to a leaked email sent to customers. HP is prepping one last run for its defunct tablet. March 8th, by Lyle Smith Intel Optane P NVMe SSD Review.
The Optane P is Intel’s latest storage product for end users. This new M.2 NVMe SSD is equipped with 3D XPoint memory and storage controllers and is designed for fast application loading, RAID configurations, and fast boot for mobile and desktop platforms.
EMC World in Las Vegas just wrapped up a couple hours ago, and I thought I would share my thoughts on the Unity product line that was officially announced here. What it is: Unity is the next evolution of EMC’s midrange storage array.
It would fall into the traditional dual controller storage array category, [ ].
Enabling VASA against an EMC VNX is very simple. As of OE (Flare) for Blockthe VASA provider is embedded in the storage processors. The same is true for OE for File and Unified systems, where the VASA provider is embedded in the Control Station.Download
