Could VSAN replace VSA?

29 May 2014

Reading Time: 3 minutes

VMware vSphere Storage Appliance was a software-based shared storage solution that enables high availability and automation in vSphere without shared storage hardware (for more information see this post). VMware has announced the End of Availability of all vSphere Storage Appliance versions, effective April 1, 2014. After this date you will no longer be able to purchase this product.

All support and maintenance for vSphere Storage Appliance 5.5 will be unaffected and will continue to follow the Enterprise Infrastructure Support Policy. The End of General Support life date for customers with vSphere Storage Appliance 5.5 remains September 19, 2018.

According to the related FAQ, there isn’t a direct replacement for vSphere Storage Appliance, customers who meet the hardware requirements can choose to upgrade to VMware Virtual VSAN. A vSphere Storage Appliance to Virtual SAN upgrade SKU will be available.

VMware Virtual SAN Observer

VMware Virtual SAN (or sometimes called also VSAN) is a powerful solution to implement an hyperconverged storage solution available, as a separated product, for vSphere 5.5 U1 environments.

Actually, although it is a 1.0 version, is almost promising, but some UI pieces is (in my opinion) still missing: the vSphere Web Client is the management tool, but the VSAN dashboard is really limited an several other information (most could be obtained from the performance monitor) could be added to provide, for example detailed usage information.

To be honest there is an experimental feature called VSAN Observer that could give you most of those data in a dashboard oriented way. I suppose also that there could be a future version of VMware vCenter Operations Manager with detailed VSAN information.

Using Linux in a vSphere Console

Reading Time: 3 minutes

Using Linux as a guest OS in a VMware vSphere environment it’s, of course, well supported and more distributions are officially supported in vSphere 5 making more easy deploy Linux VM or Linux based virtual appliances.

For the remote management a good option it’s usually use the SSH protocol, for the initial installation (or other special cases) you will need to use vSphere Console.

Using the client from a Linux box could be difficult but with the new vSphere Web Client not so much, for more information see the KB 1006095 (Availability of vSphere Client for Linux systems) or see also Access VM Consoles From Linux.

Then there are a couple of notes if you need a GUI or a text console.

Installing System Center VMM 2012 R2

Reading Time: 5 minutes

Microsoft System Center Virtual Machine Manager (VMM) is the management tool for virtual environment based on Microsoft Hyper-V (but note that it can also manage XenServer and vSphere infrastructures). It provide also management functionality for other “fabric” components (like storage or network).

It’s not mandatory (compared to VMware vCenter that is needed to implement most of the cluster features, you can manage an Hyper-V environment with the Windows MMC snap-in or via PowerShell), but could be useful to manage the entire infrastructure from a single pane. And also it provide some new features, like library management (in order to use template), P2V and V2V functionalities, cloud (IaaS) abstraction, self-provisioning, …

Configure SSD on Dell PowerEdge with PERC

Reading Time: 3 minutes

If you use SSD disks connected to a RAID controller like the Dell PERC (common in most Dell PowerEdge server), is common that the disks may be not recognized as SSD on the upper level. Because this type of RAID card cannot have a pass-thought feature (or VSAN friendly in VMware world) and is threated as a common virtual disk.

If the purpose is just add the SSD as a cache system, you can use the integrated (in most recentrly PERC) feature: CacheCade is used to improve random read performance of the Hard Disk Drive (HDD) based Virtual Disks. A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. SSDs significantly increase the I/O performance (IOPS) and/or write speed in Mbps from a storage device. With Dell Storage Controllers, you can create a CacheCade using SSDs. The CacheCade is then used for better performance of the storage I/O operations. Use either Serial Attached SCSI (SAS) or Serial Advanced Technology Attachment (SATA) SSDs to create a CacheCade.
