HP gives QLogic, Emulex FCoE silicon a ride Hewlett-Packard is adopting new Fibre Channel over Ethernet chips from
Emulex and QLogic in its latest round of data center systems, giving a
much boost to the upcoming suppliers who face competition from
entrenched chip designers including Broadcom, Intel and Marvell. Hitachi Storage Update Aims To Cut Data-Center Costs Hitachi Data Systems is updating the capabilities for its Adaptable
Modular Storage 2000 (AMS) line of products to increase storage density,
configuration options, and protocol flexibility. The new features
include SAS disks for high-density trays and an expanded capacity for
rack mounting, enabling what the company called "extremely large
capacities" -- up to a full petabyte on a single floor tile. For the AMS 2100 and 2300, Hitachi is offering expanded host port options to allow for combined Fibre Channel and iSCSI ports on the same system, or to add more Fibre Channel host ports. The use of iSCSI and Fibre Channel multiprotocol solutions allows customers to protect their storage system investment, Hitachi said, while they might be evaluating a protocol switch. Reduce Costs, Increase Utilization The AMS 2000 family of products is a storage platform designed to provide what the company described as flexible, "cost-effective performance" through three models -- the 2100, 2300 and 2500, which differ in capacity, connectivity, performance and price. The company said the AMS 2500 can achieve better than 89,000 IOPS, a SPC-1 benchmark measurement from the Storage Performance Council. In its announcement, Hitachi pointed to flexible solutions in which customers can start small and then expand the number of host ports as data-center needs grow. Mike Walkey, senior vice president of Hitachi's Global Channels and Solutions, said that, by allowing companies to start small, "this new solution gives our partners the ability to achieve energy efficiency without compromising the reliability, availability or security of their customers' IT infrastructure." He added that the new capabilities continue to "empower channel partners to reduce their customer costs while increasing asset utilization" in the data center. The options to increase utilization include a SAS disk option for a high-density expansion tray, and host port expansion slots for AMS 2100 and 2300 controllers.... www.cio-today.com | 6/28/10 8:17 PM Brocade, HP unveil data center extensions Brocade this week unveiled data center products available from OEM HP that are designed to support next-generation Fibre Channel rollouts anchored to optimizing application performance and scaling virtual machines. www.topix.net | 6/24/10 10:30 AM Israeli start-up claims huge boost to SSD reliability Israeli start-up Anobit Technologies announced its first solid-state

SeaMicro Uses 512 Atom Processors for Internet Server A Silicon Valley startup is using a processor primarily found in mobile
devices for a new kind of cloud-computing server. On Monday, SeaMicro
unveiled its Internet-optimized x86 server, based on 512 Intel Atom
processors. The model, SM10000, is described by the Santa Clara, Calif.-based company as the "ultimate rethink of the volume server." It said the server is specifically designed for the workloads and traffic patterns on the Internet, and that its approach "dramatically reduces power draw and footprint without requiring any modifications to existing software." 'Fundamental Server Design Mismatch' The company said the SM10000's key benefits include using a quarter of the power and taking up a quarter of the space as an equivalent, best-in-class volume server. The new unit can run off-the-shelf operating systems and applications without modification, and has an architecture flexible enough to support any CPU. Other technology innovations include a patented new CPU I/O virtualization, elimination of 90 percent of the components ordinarily required for virtualization, and a supercomputer-style interconnect fabric linking the 512 mini-motherboards into a single system -- which results in a throughput of 1.28 terabits. The architecture supports any protocol, including Ethernet, fibre channel, or data-center Ethernet. The unit's 512 Atom processors run at 1.6 GHz, with one terabyte of DRAM. SeaMicro is especially promoting the power savings. The company cited reports from Google to the effect that, if current power requirements continue, the cost of energy for a server will, over its lifetime, surpass the initial purchase cost. SeaMicro said its approach deals with a "fundamental server design mismatch." Servers, it said, were initially designed to solve a "relatively small number of very hard problems," a situation that was changed by the Internet. Stealth Mode In a data center focused on the Internet, it said, the challenge is handling many relatively small, independent tasks -- searches, social networking,... www.cio-today.com | 6/14/10 8:35 PM Re: IXS Server Cards "Actually iSCSI is being phased out."

High Availability MySQL Cookbook from Packt Publishing by Alex Davies.
Overall, I found the book to contain some good hidden Gems.The book is a
mixture of MySQL Cluster (NDB), Replication schemes, some performance
tuning, some minor kernel tweaking, and some more exotic approaches to
common High Availability problems. Overall, I found this book very
informative and a good read.Now the specifics, the book starts out on
NDB and stays focused on this fact for about 60% of the book. The next
20% is on mySQL replication then about 10% of the book is on tweaking
kernel, mysql, network settings to get the most out of the system. The
last 10% is a mixture of uses of exotic systems such as GFS, Conga,
ISCSI and how to use these shared storage techs with mySQL.High
Availability MySQL Cookbook, is a good read, and jogged my memory on NDB
(since I do not use it on a day-to-day basis). If you are looking for a
good reference on how to get an HA system up then this is a good book
for you. If you are looking for why to use NDB over mySQL multi-master
replication, this is not a book for you. The
“why-to-use-this-over-that” is not the scope of the book.
The drawbacks and concerns of what technology to use are not a focus of
this book, and should not be. It is assumed that the reader knows which
direction to go into for the most part or gives the reader enough
information to set up and environment to see which way to go.In
conclusion, I like this book. I think it is rather concise, and right to
the point, which either gets you started into building HA systems or
gives you a good reference for an existing HA environment.

Two years ago we read about how the magnetic disk drive would be dead in a couple of years at the hand of flash SSD. Guess what, it is a couple of years later and the magnetic disk drive is far from being dead. Granted high performance Fibre Channel disks will continue to be replaced by high performance, small form factor 2.5" SAS drives along with continued adoption of high capacity SAS and SATA devices. Likewise, SSD or flash drives continue to be deployed, however outside of iPhone, iPod and other consumer or low end devices, nowhere near the projected or perhaps hoped for level. Rest assured the trend Im seeing and hearing from IT customers is that some will continue to look for places to strategically deploy SSD where possible, practical and affordable, there will continue to be a roll for disk and even tape devices on a go forward basis. Also watch for more coverage and discussion around the emergence of the Hybrid Hard Disk Drive (HHDD) that was discussed about four to five years ago. The HHDD made an appearance and then quietly went away for some time, perhaps more R and D time in the labs while flash SSD garnered the spotlight. There could be a good opportunity for HHDD technology leveraging the best of both worlds that is continued pricing decreases for disk with larger capacity using smaller yet more affordable amounts of flash in a solution that is transparent to the server or storage controller making for easier integration.

RAID Controllers Cache Management ? Missing Features We all know how important hardware RAID controllers are in today’s
data storage performance especially when dealing with large data sets.
If we look at the trend from now to couple of years back; they really
evolved rapidly with lot of useful features and their usage also grown
as most of the new servers by default has one or two controllers
built-in (one for internal and another one for external storage array or
for redundancy). Few popular RAID controller vendors in the
market: PERC Controllers from DELL Adaptec RAID Controllers
3Ware RAID Controllers (now part of LSI) LSI RAID Controllers Smart
Array Controllers from HP Intel RAID Controllers More or less
everyone supports all common features and differs in number of ports,
protocol support (ISCSI, SATA, SAS, HBA/FB), transfer speed, RAID
levels, total disks support, cache size and its management. Controller
Cache – Database Workloads For database OLTP workloads (IO bound),
controller cache plays a crucial role for overall write or read
throughput, depending on how the cache is used. Most RAID controllers
are equipped with either 128MB or 256 MB or 512MB cache, and newer
controllers like HP Smart Array P812 supports 1GB. Write-back mode
improves the writes performance by magnitude as the write request is
returned as completed as soon as the data is in the controller cache
without actually writing to the disk (that’s why controller needs
a BBU, Battery Backup Module so that there is no data loss on power
failures) In case if you enable the read ahead from the controller
(sometimes good for OLAP workloads or ETL data warehouse, especially
adaptive read ahead due to heavy sequential access); then the same cache
is used to store the pre-fetched data that can be satisfied later from
the cache without hitting the disk. But in case if the database system
does read ahead (like InnoDB), then it is better to turn off read ahead
from controller to avoid page trashing. For some workloads, the
controller cache can also cause negative performance if the cache is not
properly utilized by the controller. Missing Cache Management Tools At
present, none of the controllers either supports any cache management
tools nor exposes how the cache has been actually used, so that one can
adjust the cache according to the workloads for improved performance.
Some of the missing features: A way to flush the data from cache to
disks, so that the systems can be taken for offline maintenance. Right
now there is no easy way to flush data from cache to disk; other than
some of the controllers will indicate through LED whether data is in the
cache or not Way to set the cache threshold in time or %, so that it
can start flushing to disk once it meets the threshold value. For
example; if you notice big spikes from RRD graphs for every few minutes,
then one can adjust the threshold to evenly distribute the load.
Cache usage statistics (writes data size, read ahead data size etc ), so
that workload can be adjusted to yield much better results Splitting
of cache between reads and writes either in size or by %; so that they
do not overlap and cause performance issues. For example; one prefers to
set 20% for read ahead data and 80% for writes. Only HP Smart Array
controller supports this feature at present. As you get more control
over the controller cache, the more you can tweak and adjust the
workloads to get improved performance. Hopefully one day all vendors
will expose more cache management options.
