Re: Starwind and Freenas

Hi!

That sound complex and provides a lot of space for problems, where nobody can help you.

I would avoid to combine the two products.

Re: Max Cache Size

Hi!

So, if I have 30 TB, I would create 5 volumes with 6 TB and each one with 6GB L1-Cache --> 30GB L1-Cache?

Re: Max Cache Size

Hi Oleg!

Thats quite vague...

In case of a HA-system, the loss of the cache should not be critical. What is the maximum size, you recommend?

Re: VMware Linux VSA

Hi!

Are there any news about the performance of the Linux-VSA on writes? Are you able to get > 100.000 IOPS on 8k-writes?

Regards

Max Cache Size

Hi!

In the past, there have been some limitations in the L1-cache size of a HA-cluster.
Are there any improvements? Whats the maximum size, you recommend?

Re: Starwind and VMWare - Delayed Ack

Hi Oleg, thank you for your answer. Its not possible to define "Delayed Ack" per volume, as I have to configure it for the whole initiator (and there is only one software-iscsi-initiator). Does Starwind have any problems with Delayed-Ack=yes? I can only use Starwind, if it does not interfe...

Starwind and VMWare - Delayed Ack

Hi!

Is it safe to use "Delayed Ack = Off" with Starwind?

I need to disable it for another storage, but both share the iSCSI-software-initiator...

Thank you for your help!

Re: LSFS - Snapshot and async replication - all flash

Hi! My workload is a vSphere infrastructure. I am using 4 procudtion-hosts and a DR-vSphere-node. My goal is to replicate the data to the DR-location to be able to bring the VMs up, there, if needed. I am testing some different solutions, but I hope to be able to stay with starwind (as I really like...

Re: LSFS - Snapshot and async replication - all flash

Hi anton! At the moment, there is no replication solution except zerto (which I know). Veeam-replication 9.5 leads to an outage on every replication... Everytime, Veeam is doing a snapshot or deleting the snapshot, 1-2 pings of the VM is lost and every UDP-packet, that is sent to the VM is lost. -->...

Re: LSFS - Snapshot and async replication - all flash

Hi!

I did some performance-tests with LSFS and full-flash / NVMe, but results are not very good on random write.
It's sad, that there is no oterh snapshot/replication-possibility with starwind.

Re: LSFS - Snapshot and async replication - all flash

Hi! It would be great, if you could give me some input on: - Can there be "nearly" unlimited snapshots? - Is there any possibility to see the space, that is consumed by every snapshot? - Do you have retention-policies like: Keep 1 hourly snapshot for 24 hours, 1 daily snapshot for 30 days?...

Re: LSFS - Snapshot and async replication - all flash

Hi Michael!

Thank you for your answer!
Can LSFS provide a good performance on flash? I did not find any informations about this?

Another question: does LSFS provide any "system" to do integrity checks like zfs or refs?

Re: LSFS - Snapshot and async replication - all flash

Hi!

So, there is no "starwind-solution" for All-Flash, if snapshots and aynchronous replication are needed - right?
