Removed from DSS v7 Lite or all v7 versions?
Actually, PCIe SSD have considerably better performance that the SATA or SAS SSDs. The use of the PCIe provides much higher bandwidth and lower latencies -> fast throughput, more IOs.
As for the...
The availability of PCIe SSD adapters has exploded in the last 12 months. I don't, though, see any of these devices list on the HCL.
Are there any plans in this area, or is it a case that as...
I don't know if defragmenting would actually accomplish anything.
Since iSCSI LUNs are virtual block IO devices, the seek time optimization which a defragmenter provides would be of little value,...
Roel,
Although Open-E support for TRIM is important, the larger problem is that Adaptec/LSIU and Areca do not support TRIM in their RAID disk controllers.
There are some SSDs which support...
@Al-S,
As far as I can see the graph/stats are the same as V6, and are equally as criptic. So, the answer for dagar is: No, there are no changes in the graphs/statistics.
It would be helpful...
Todd,
To be clear, I am not looking for the DR to be part of the cluster. I am looking for the DR to simply be a backup of some cluster volumes.
Am wondering about the new Active/Active functionality as it relates to how the systems would be configured.
Some other active/active solutions have two servers/heads/controllers which are...
I haven't had a chance to download the new version, so forgive the question.
Does the Active/Active failover pairing also support having a replication task to an additional/third (DR) location?
I think you will also find that Windows Server 2012 has had improvements in failover tolerance.
The price list is not clear on this.
Curious, what type of HDDs and disk controllers are you running in your config? Separately, how are you measuring throughput?
In future, I would suggest that a more "direct" answer would be appropriate.
By "direct answer" I mean:
"We discovered some issues in ESX functionality when updating from older DSS V6 versions,...
We ran into a similar problem with our hardware, so we install open-e on a 'plain old' flash drive...
Define/clarify what you mean by "work in the cluster".
Do you mean, the VM can run as part of a VMWare HA cluster? Yes.
Do you mean, the open-e Lite can host storage in open-e active/passive...
I just re-reviewed the performance number from the site and I can't find any matching details for the config which provided the 917MB/s numbers.
In general, I have to say that unless you run the...
It is not surprising for a vendor to try to dismiss another vendor's products.
One thing to consider... does the AvroRAID product support the same feature set as Open-e? Volume Snapshots?
...
For myself, "LAN speed" doesn't refer to the connection speed but rather the connection latency. A 10Mb/s connection with a <1ms latency would be worth a lot more than 1 Gb/s connection with a 10ms...
But how would the OCZ device driver be installed?

Butler 1.5??? Huh?
In order to be used as a read cache data must be written to the SSD.
The card/software decides what blocks are used most often and writes those to disk first, then to the cache. (So, if the SSD...
Wikipedia says yes, so it must be true! ;)
I think you have confused:
1 - physical PCIe hot-plug features with the ability for an OS to recognize new PCIe added via hot-plug.
2 - the...
Where are your questions??
Have you tried use one of the MGE Pulsar entries? (i.e. lie to setup)
I would wonder if "dd" does a random IO test and "iozone" does a sequential IO test.
There is a significant difference in the performance of the 2 methodologies.
