Going Tapeless in Enterprise

by dave on January 28, 2009


I was asked the other day about the potential for finally going tapeless in Commercial and Enterprise spaces.  Truth be told, this is becoming a more common occurence as those mechanical beasts hit the tail-end of their maintenance windows.  With that in mind, what are some (not all) of the business drivers that move enterprises from tape to disk (or other mediums)?

Part of the beauty of ESX 3.x from a hardware support standpoint was the addition of SATA as a viable install media for the hypervisor and service console.  However, opening up support for SATA also included a few hiccups along the way, most related to the SATA controllers officially supported by VMware.  For folks like myself who spent a lot of time with AMD-based platforms, the only real choices for SATA controllers (onboard the motherboard, not discrete) were offerings from Broadcom and nVidia.  This post will highlight how to configure your ESX 3.x host to use nVidia SATA controllers.

Anyhow, let’s get straight to the point here: the NX4 is here. It has arrived in all of its SAS/SATA disk goodness. It brings with it CIFS/NFS capabilities, iSCSI for IP-based block level access, and 4Gb/s Fibre Channel for those moments where massive bandwidth and low latency are priorities. Sounds good, huh? Let’s toss in IP-based and Fibre replication facilities, auto volume management (for thin provisioning), and writable Celerra snaps and you’ve rounded out the solution completely. Did I mention that you’re going to layer this on top of the category-busting (sales-wise) AX4-5? [click to continue…]

June 17, 2008

Having missed last weeks Search Term post (which actually was a good thing), I decided to delve deeper into the search term logs and see what the top reoccurring searches were for this week. Imagaine my suprise (or not) when I found that RAID and RAID group expandability was a consistent theme. To […]
