Dell EqualLogic is a well know name in iSCSI storage and it does not any presentation. But the “converged” version for the M1000e blade enclosure maybe need more information. I’ve see a prototype (Code name: Colossus) during the Dell Storage Forum at London and it was absolutely interesting and promising. The final product is called Dell EqualLogic PS-M4110 Blade Array and it’s fully compatible with the exiting PowerEdge M1000e enclosures (designed and realized several years ago) with the only requisite to have at least one 10Gbps fabric (and of course have an updated firmware).

Recently I’ve got a strange issue with an Dell EqualLogic environment and I’ve not found any useful info about the related error message: Subsystem: MgmtExec Event ID: 8.3.48 Schedule Replica oraria aborted because the group was too busy processing a max-keep value change to create the operation scheduled for time …

For the new SRM 5.1 a new EqualLogic SRA is required (version 2.2) and it’s available both on EqualLogic site (in the support section) and VMware site (in the SRM download page). The upgrade procedure is simple and it’s described in the previous post. You have simple to run the installation. But there is now a new interesting option on how storage replication (note that are used asynchronous replication) are handled:

There are several rumors about a virtual edition of EqualLogic, targeted especially for the SMB segment and/or the ROBO scenarios. Several storage vendors are proposing a virtual appliance version of some of their solutions (like HP with the virtual “LeftHand”) and actually Dell has nothing in this specific area. The virtual EqualLogic could be the most reasonable product, just because the Compellent series is target for the high end area and usually has a mapping tighten with the hardware (let’s consider how PCI-e slots must be populated). The PowerVault series is just a re-branded of […]

In the previous post I’ve describe how migrate volumes across two (or more) EqualLogic in the same group, using different storage pools. In the same way is also possible migrate the data on the disaster recovery site: in this case data are the remote volume replicas that are stored in a single container called delegated space. Each destination of a (asynchronous) replication must have a proper delegated space (and only one!), and a delegated space can be stored on a single storage pool.

During an array migration usually you can use application level trick to move your data between the old and the new array. For example with VMware vSphere you can use the Storage vMotion features (now added also in lower edition of vSphere 5.1) or with Microsoft Hyper-V 3 you can use the new Storage Live Migration feature. But in some case you may have also an option at storage level. For example to migrate across two Dell EqualLogic array (also different models) you can use the embedded function.

In the previous post, I’ve described how is possible integrate the Dell storage array management with the new Microsoft System Center VMM 2012. But of course it is possible to do the same (and from longer time) also using VMware. With VMware vSphere we could have two different approaches for the integration: One is simple add the storage interface (or part of it) in the tab and/or the menu of vSphere Client by using a vCenter Server plug-in. In this case the integration could be strong or weak, but usually differ from storage and storage. […]

As written in a previous post, with Microsoft System Center VMM 2012 is possible manage some (supported) storage array using a SMI-S provider. In the Dell storage portfoglio, the only solution that (one month ago) had the SMS-S support was the PowerVault MD3xxx series, and althoug not mentioned by Microsoft, was possible include them in the System Center fabric (as written in specific post).

Has written in the previous post, Dell EqualLogic Host Integration Tools for Linux 1.1 officially support only a few Linux OS, but it can work fine also on others. Actually the distributions is RPM based, so there is a bigger effor to port it to other distro, like Debian and Ubuntu. I’ve tried with a updated release of CentOS 6.2 and it works fine, but you will need some packages that may be not installed (and also dkms that is not included in the installation source): yum install iscsi-initiator-utils libpcap gcc make rpm -Uhv […]

After a beta period, the Dell EqualLogic Host Integration Tools for Linux V1.1 has achieved (some days ago) Early Production Access status and is available for download via the standard Dell EqualLogic download site. Note that Early Production Access software is fully supported for production use. As a reminder, HIT/Linux includes tools that provide tight integration of EqualLogic PS Series arrays with Linux environments for enhanced protection, performance and simplified configuration and administration of EqualLogic PS Series storage arrays. HIT/Linux 1.1  feature enhancements over the previous release of HIT/Linux 1.0 include the following: Auto-Snapshot Manager/Linux […]

Some days after the recent acquisition of AppAssure, Dell has announced new models of EqualLogic storage and the new generation of PowerEdge servers. For the EqualLogic the announce was “obvious”: after the new models with 1 Gbps connectivity (PS6100 and PS4100 storages), announced on August 2011, the 10 Gbps models (PS6110 and PS4110) were just the next step. For more information see the post on the The Register and on the Dell Community. More interesting the announce of the new PowerEdge generarion (a logical move after the HP announce of his new generation): the G12 […]
