HP have recently released their latest generation of the world’s best selling servers. Having corrected most of the errors in the product specifications – some of which were first reported by the eagle-eyed staff at EACS – we now know the fine detail of what these systems do.
The Gen8 release applies to the dual socket models – the DL360 and DL380 rack mount, the BL460 blade and the ML350 tower, the four most popular models in the range. The g7s will continue to be available for some time.
So why would you buy a Gen8 server?
Reason 1 – to save money.
The Gen8 models offer 4, 6 and 8 core processors and all bar the blade model will let you deploy up to 756GB ram, just 512GB in the BL460. Ideal if you have a really demanding application or, much more likely, you are trying to consolidate as many physical servers as possible onto as few hosts as possible for virtualisation purposes. If you had planned to consolidate onto 4 dual socket 6core servers on the old g7 model you can now achieve the consolidation onto 3 dual socket 8core servers with the Gen8s. Apart from saving space and power you will now reduce your costs of Vmware and/or Microsoft per socket licensing by 25% as you will only need 6 licences instead of 8.
Reason 2 – to deliver higher performance.
Apart from offering more than double the memory capacity of their predecessors, the Gen8 models offer 4 channels of memory against only 3 in the g7, so an extra concurrent pathway is provided to the installed memory to boost the performance. The 8core Gen8 offers faster memory too – 1600Mhz against a maximum of 1333Mhz in the g7. The Gen8 has also eliminated the performance hit if you have to use the second memory bank. In the g7, if you fitted 1333MHz ram into memory banks 1 and 2 all the memory dropped down to 1066MHz. This doesn’t happen in the Gen8, so up to 16 DIMM slots can operate at top speed against only 6 in the g7. If you used the third row of dim slots in the g7 all the memory would drop down to 800MHz. Gen8 only drops to 100MHz if you use the third row of DIMMs – slots 17-24.
Reason 3 – improve your management – ILO4.
HP’s Insight Lights Out (ILO) management built into each Proliant has evolved into its 4th generation providing more environmental and power management capabilities and delivering greater remote management capabilities – more details HERE.
Reason 4 – easier to handle, less easy to damage.
The Gen8 is apparently completely tool-less, so you should be able to strip it down and build it back up again without a solitary tool. More useful for the masses is a new design so that you should be able to install an additional processor without bending any of the pins which is an expensive mistake to make.
Reason 5 – improved raid performance and enhance data protection.
The Gen8 has the new Smart Array 420 raid controller which improves throughput on intensive applications, including when used with SSDs. It offers a chargeable option of RAID 1 Advanced Data Mirroring (ADM) – a three way mirroring so you can lose one drive in a RAID 1 or 1+0 configuration and not suffer degradation as the array is being rebuilt. Quite smart if you need this level of protection and want to contribute to the global shortage of disks!
Reason 6 – future-proofing your networking.
The Gen8 offers models with 10GbE (1/10 autosensing) on board so if you have plans to upgrade your networking core to 10Gbe this option is available delivering 1GbE today and 10GbE when you need it. On the BL460 Gen8 blade this is the only standard configuration available.
