P4500G2 LH Cluster Showing Incorrect Storage Values
Good day everyone,
I have a P4500G2 cluster with 8 nodes running 12.5. When we added the 8th node to the cluster it suddenly went to 100% utilization, where if you look at the used space .vs. total space we should be a little less than 50% (see attached screen shot). Because it "thinks" the cluster is at 100% we can delete volumes, shrink volumes, or any other management functions.
Any thoughts on how we might get this cluster to recalulate space?

Fibre Optics SAN
Hi Friends,
What type of Fibre optics cables available(Single and Multi Mode)? I would like to understand the distance, speed limitations. I am very much new to SAN technology, hence wanted to understand how it works. Also how can we achieve a fibre optic cable connectivity between 2 Data Centers separated by 100-500KM?

What is Block Data?
Hi Friends,
I get the basic understanding of what a block data is, in the sense the blocks are the amount of data stored physically in a hard disk. Is my understanding correct? (I am referring to the context of SAN storage technology). How does it write the block into the disk? Whats the relation with file system and block?
↧
Re: What is Block Data?
Yes
"Block Storage" or "Block Data" means you create a Volume (LUN) on the Storage an present (export) it to one (or more) Server.
The Server sees the Volume a an local Volume format it in the Filesystem of the OS (NTFS, VMFS or whatever) and than wirte in Blocks (Cluster).
In "File Storage" the Storage present a Share (CIFS, NFS) to the Server(s) and the Server write the Data to the Share.
The Server did not know the Format of the Filesystem or where the Files reside.
↧
Re: Fibre Optics SAN
You can get both.
For Server and Storage "normal" is Multimode.
For the Switch you can use Multi- or Monomode.
Google for "SAN Design Reference Guide" on the HPE Sites, this should give you all the answers you need.

Factors that affect the timelife of a FC disk
Hi,
We have an array EVA P6500 with two controllers. This array was bought in october of 2011.
Recently, we have issues about several FC disk failed (15k rpm). We have five failed disk in the last two months, . This array is not in support contract.
I know that the age is a factor for probability of get a disk fail event, but, my question is:
What other factors can affect the timelife of a magnetic disk, specially in enviroment of EVA P6500 ?I have a similar array in other side with no problems.
Please provide me any clues according your experience.
Thanks in advance.
Roger

Re: What is Block Data?
Block storage can also have different RAID levels and be stored in multiple places (network raid) for resiliency.
It can also have snapshots.
↧
Re: Factors that affect the timelife of a FC disk
It also depends if these are all the same vendor model and if all manufactured at the same time.
If that's the same, it would also depend on the duty cycle and finally the environment.

HPE FC SN3000B firmware upgrades
Hi
I need to do dome firmare upgrades from v7.2.x to v8.0.x on a couple of SN3000B switches. Reading through the release notes I can either do this distruptively but in fewer steps or non-disruptively in more steps. To minimise risk I would rather do more steps that are non-disruptive but I want to know if this is truely non-disutptive using this approach. The environment is very simple with 2 x FC switches, a small number of hosts and single storage array. Whereas some hosts are multipathed there are a couple of hosts with only a single HBA port and therefore connected to just one switch. My interpretation of 'non-disrutpive' is that a single pathed host will not suffer any outage when the switch is upgraded - is this what 'non-disruptive' means in the HPE\Brocade world or do I need to **bleep**down any single pathed hosts first?
Thanks in advance

Re: HPE FC SN3000B firmware upgrades
Hi
you can do it non-disruptively it works fine
you should how ever do it in not in peak hours to keep
on the safe side. but non-disruptively meens the ports don't
go down only the interface restarts.
I have done it many times.
Regards

Re: HPE FC SN3000B firmware upgrades
Great - many thanks
And the interface restart doesn't impact IO down that path?

Re: HPE FC SN3000B firmware upgrades
Hi
managment interface restarts ports to host stay up
only equipment I saw that can sometimes notice
this are tape devices
